Configuring & Running Specific Methods in Maven Projects in NetBeans IDE

In yesterday's blog entry, you saw that a specific test method, i.e., the currently focused test method, can be run, instead of all the test methods, i.e., you have fine-grained control over specifically which test method is executed. However, is it possible to configure that test method, passing in JVM arguments for that specific test method, for example?

Right-click the application and choose Properties, or choose Properties from the File menu, and assuming you're working on a Maven-based application, you'll see the tab below in the Project Properties dialog:

Above, you see the definition of the action that is run when "Test File" is called on a file, which can be done via a menu item or via the keyboard, i.e., by default, Ctrl-6.

Here you can see that I have customized it so that a specific test method is invoked, instead of all the methods in the class:

In the above example, a test method named "testPrintMessage" is run when the "Test File" action, e.g., via Ctrl-6, is performed.

That's because, as my colleague Theofanis told me today, these are Maven commands one can run on the command line, and the above is the equivalents of the below:

mvn -Dtest=a.b.c.MyTest surefire:test would run all tests in MyTest test class

mvn -Dtest=a.b.c.MyTest#testMethodName surefire:test would only run testMethodName in MyTest test class

When you click the Add button above, you are helped in different ways in seeing the options available that can be added:

However, instead of overriding the "Test File" action, you can create custom actions for each method you want to have control over, after you click "Add Custom" below:


After you add a custom action, like above, you can invoke it by right-clicking the file on which you want to run it:


Now, in the Output window, I can see that this is part of the command that NetBeans runs for me when I click the above menu item:

-Dtest=com.mycompany.hello.MainTest#testPrintMessage -Dvertx.timeout=9999

Hope this answers Martijn Verburg's question on Twitter:

https://twitter.com/karianna/status/524521480621531136

Handily, you can also run the custom action directly in the editor, after right-clicking it:


One nice improvement would be if you could map a keyboard shortcut to your custom actions, so you wouldn't have to right-click on a file or in the editor but just press some keys on the keyboard. But simply right-clicking in the editor and then clicking the menu item, as shown above, is not bad at all, pretty handy that you can extend the NetBeans Java Editor with your own custom Maven actions, isn't it? :-)

Once you've created one custom action, like the above, all the next ones are simply a matter of writing in the XML file that is created the first time you create a custom action:

The above "nbactions.xml" file looks as follows, after the steps I took above:

<?xml version="1.0" encoding="UTF-8"?>
<actions>
    <action>
        <actionName>CUSTOM-"testPrintMessage" method</actionName>
        <displayName>"testPrintMessage" method</displayName>
        <goals>
            <goal>test-compile</goal>
            <goal>surefire:test</goal>
        </goals>
        <properties>
            <test>${packageClassName}#testPrintMessage</test>
            <vertx.timeout>9999</vertx.timeout>
        </properties>
    </action>
</actions>

So, you want to give yourself the option of running each test method separately? Just copy the action elements above, customize them, and automatically when you right-click the file or in the editor, you'll see a new menu item that connects to the related action in the file above.

Lazy Injection with javax.inject.Provider

javax.inject.Provider is the minimalistic version of the javax.enterprise.inject.Instance interface. In fact Instance inherits from Provider

For on-demand injection of components / resources inject them as Provider:


@Model
public class Index {

    @Inject
    Provider<Boundary> boundary;

    public String getMessage() {
        return boundary.get().message();
    }

}

The injected component is unaware about the laziness:


@Stateless
public class Boundary {

    public String message() {
        return "Good morning";
    }
}

Instance comes with additional functionality: see also Interfaces on Demand with CDI and EJB 3.1

[See also an in-depth discussion in the "Real World Java EE Patterns--Rethinking Best Practices" book (Second Iteration, "Green Book"), page 235 in, chapter "Plugin"]

NetBeans Translation Tip #2: Do Not Translate USE_MNEMONICS

So you're working on the NetBeans Translators project and you run the application, with its translated bundles, and then you see this error message:

WARNING [org.openide.awt.Toolbar]: Error in AWT task
java.lang.AssertionError
	at org.openide.awt.Actions.setMenuText(Actions.java:290)
	at org.openide.awt.Actions$MenuBridge.updateState(Actions.java:1266)
	at org.openide.awt.Actions$Bridge.prepare(Actions.java:902)
	at org.openide.awt.Actions$MenuBridge.prepare(Actions.java:1221)
	at org.openide.awt.Actions.connect(Actions.java:201)
	at org.openide.awt.Actions$MenuItem.(Actions.java:1571)
	at org.openide.awt.DynaMenuModel.loadSubmenu(DynaMenuModel.java:138)

You also, assuming you're translating into French and have already translated the text in the error dialog below, see this dialog, once the application has started:

And you're unable to access any of the menu items in the menubar.

An error message that contains "setMenuText(Actions.java:290)" is one that can be figured out by thinking about where menus are defined, in the NetBeans Platform source code. This is done in the UI Utilities API module, which is org-openide-awt.jar.

When I went there, in "LocalizedNetBeans", I found that there are two translated bundle files there, both in French:

Notice the one in blue above. Through a process of trial and error, I discovered that the key "USE_MNEMONICS" should NOT be translated. If you translate USE_MNEMONICS, the error described above occurs. Simply do not include it in the bundle file shown in blue above, in the 'branding/modules/org-openide-awt.jar' folder. Delete it from there, as I did (which is why the file is shown in blue) if you have it there.

And then the problem is solved: the error message above is not shown and menu items can be accessed again, as normal.

PS: Also see tip #1.

Fixing the Ribbon Bar Integration Tutorial

The NetBeans Platform Ribbon Bar Integration Tutorial has an Installer class that needs to be rewritten if you're using it with NetBeans Platform 8.0 and 8.0.1.

In the Flamingo Integration module, delete the content of the Installer class, in the modules.flamingo package, and replace it with the code shown below:

https://netbeans.org/projects/platform/lists/dev/archive/2014-10/message/107

The problem with the original Installer class in the repo is that it is a little bit hacked together, i.e., it uses the ModuleInstall class, registered in the Manifest, but then delays loading via SwingUtilities.invokeLater. So, when the loading sequence in the NetBeans Platform changes, even slightly, as it does from release to release, with performance enhancements and so on, the hacked code stops working correctly... and the rewritten components, i.e., the ribbon, is loaded incorrectly.

UIDefaults.getUI() failed: no ComponentUI class for: org.pushingpixels.flamingo.internal.ui.ribbon.appmenu.JRibbonApplicationMenuButton[,0,0,0x0,invalid,alignmentX=0.0,alignmentY=0.0,border=,flags=16777216,maximumSize=,minimumSize=,preferredSize=]
java.lang.Error
    at javax.swing.UIDefaults.getUIError(UIDefaults.java:732)
    at javax.swing.MultiUIDefaults.getUIError(MultiUIDefaults.java:130)
    at javax.swing.UIDefaults.getUI(UIDefaults.java:762)
    at javax.swing.UIManager.getUI(UIManager.java:1016)
    at org.pushingpixels.flamingo.internal.ui.ribbon.appmenu.JRibbonApplicationMenuButton.updateUI(JRibbonApplicationMenuButton.java:124)
    at org.pushingpixels.flamingo.api.common.JCommandButton.<init>(JCommandButton.java:433)
    at org.pushingpixels.flamingo.internal.ui.ribbon.appmenu.JRibbonApplicationMenuButton.<init>(JRibbonApplicationMenuButton.java:110)

Until you do the rewrite described in the link above, you'll see the error above when running the application and find the icon in the top left missing, as shown below.

The changed code in the link above fixes the problem.

If you feel the Ribbon application menu button, the big one top left above, is taking up too much space, you can take a look at the com.pinkmatter.modules.flamingo.LAFConfiguration class, and replace one statement with two statements, to use Bruce Schubert's rewritten application menu:

Setting The Classpath For Nashorn Script in jjs / Java 8

The Java 8 jjs interpreter accepts the -cp / -classpath argument. After setting the classpath, all the classes become available from within the executable script.

A utility class com.airhacks.naslib.Inspector in the naslib.jar (this is an sample jar) becomes available for Nashorn after setting the jjs classpath:


#!/usr/bin/jjs -cp ./naslib/target/naslib.jar -fv
//built-in variable
var args = $ARG;

var Inspector = com.airhacks.naslib.Inspector;
//class from jar, calling a static method
Inspector.inspect(args);

In case this post looks a bit crazy to you, you should join the Java 8 / Java EE 7 "More Power with Less Code" workshop :-).

YouTube: Profile That PiDrone!

Forget all the small command line tools you typically need to access a remote device, such as a Raspberry Pi. NetBeans IDE connects to the Pi for you and lets you run your application. But... you can also debug the application within NetBeans, while the application is running on the Pi. And, even more impressively, you can use the NetBeans Profiler together with your Pi.

Below, Mark Heckler shows this feature in action with his PiDrone!

Tips: NetBeans on Ubuntu

Ubuntu Linux is a very nice software development platform and NetBeans fit very well in it.

Nevertheless few tips can make our developer life easier. These tips can be applied to other Linux distributions.

1. Do not use apt-get

Apt-get is the Ubuntu/Debian tool to download and install programs from the repositories.

It should not be used to install the tools you need for development, NetBeans included.

Reasons:

  • Repositories contains old versions
  • Dependencies force you to install not needed or incompatible software

Get installation files from the main sources and install them manually in a common dir like /opt.

2. Install NetBeans on a user writable dir

NetBeans needs to update files in its own installation directory during software updates. I suggest to use /opt as the main installation dir.

If /opt is now user writable, execute the following command

sudo chmod 777 /opt

3. Watch the /tmp size

NetBeans use /tmp for temporary operations like, for example, updating Central Maven repository information. While doing this update, NetBeans saves big temporary dirs under /tmp and the update fails if /tmp has no space available.

The /tmp dir is usually small when it is mounted on a dedicated partition.

Reserve at least 1.5GByte free space on the /tmp.

See Bug 162313 for more details.

4. Save NetBeans cache in RAM

NetBeans saves configuration, user preferences and project files status in the NetBeans user dir which is located in $HOME/.netbeans/<version>.

Part of this information, mainly related to projects is considered to be a cache (= it can be recreated if deleted); the cache can be located in a separated dir with the command line –cachedir.

With at least 4 GByte RAM, we can map the cache dir to a temporary RAM on disk using Ubuntu native ram filesystem.

My preferred approach is to

- mount the /tmp to a tmpfs type filesystem, by adding the following line in the /etc/fstab

tmpfs /tmp tmpfs defaults,noatime,nosuid,nodev,noexec,mode=1777,size=2048M 0 0

This will “map” the /tmp dir into RAM up to 2GByte (see tip #3).

- map the cachedir to a /tmp/ subdir, by creating a NetBeans invocation script as the following:

#!/bin/sh
export VERSION=netbeans-8.0.1
export RAMDISK=/tmp/$VERSION
export OPTIONS=" --cachedir $RAMDISK --laf Nimbus "
/opt/$VERSION/bin/netbeans $OPTIONS &

The script will invoke NetBeans with the appropriate options.

Note: I like Nimbus on Ubuntu Unity user interface.

5. Use a SSD drive

SSD drives are an impressive speed improvement. Software development requires reading and writing hundred of files. Speed is essential to have quick feedback during our test and compilations cycles.

The SSD drive can be your main hard drive or an external one (possibly on a fast USB connections). Just place both NetBeans installation dir and your projects files on the SSD unit.

Remember to add noatime option on the mount instructions (see /etc/fstab) to avoid useless write access to the disk.

Oracle Labs to Sponsor R Plugin in NetBeans IDE

Oracle Labs have recently posted a new master thesis description for R support for NetBeans.

http://ssw.jku.at/Teaching/MasterTheses/Graal/NetbeansR.pdf

If you happen to be or to know a talented student that could do the job, please respond. Either drop a response in the comments to this blog entry, reach me some other way, or contact the initiator of this thesis, Thomas Wuerthinger (thomas dot wuerthinger at oracle dot com) directly.

However, note that you really need to be a very talented and self-motivated programmer. You're not going to focus on simple tasks and you shouldn't be someone who needs constant support and guidance. The bar is pretty high. You should be more or less an expert in R and you should be able to figure out how to provide deep NetBeans features for R, such as syntax highlighting, compilation and running of R code, error reporting, as well as code completion and debugger integration.

Oracle Labs will pay 20h/week for the student working on the master thesis outlined above.

Great news! Looking forward to seeing R take off in NetBeans IDE.

Named Parameters in Java 8

With Java 8 and the compiler flag: javac -parameters method parameter names are available via reflection. For example: the parameter names of the method hello:


public class Boundary {

    public void hello(String name, int age) {

    }
}

become accessible to the following code:


    public static void main(String[] args) {
        Method[] methods = Boundary.class.getMethods();
        for (Method method : methods) {
            System.out.print(method.getName() + "(");
            Parameter[] parameters = method.getParameters();
            for (Parameter parameter : parameters) {
                System.out.print(parameter.getType().getName() + " " + parameter.getName() + " ");
            }
            System.out.println(")");
        }
    }
}

Compilation with javac -parameters produces the following output:


hello(java.lang.String name int age )

Without the -parameters flag the names are not available:


hello(java.lang.String arg0 int arg1 )

Exercise 3 of "Exercises in Porting to the NetBeans Platform"

Pretty awesome! The long-awaited third exercise of "Exercises in Porting to the NetBeans Platform" has been published. The authors start off with the Stocks Monitor application found here and then, step by step, with a lot of explanations and code and screenshots, migrate it to a NetBeans Platform application with all the same functionality as the original application. 

At the end of the exercise, you have an application that looks like this, which monitors financial data from Yahoo Finance.

As always, the authors are looking for your feedback and interaction. The stocks monitoring application will be the basis of subsequent exercises. Right now, it consists of a single module in the application. Subsequent exercises will focus on breaking the application into multiple modules, as well as the integration of the Nodes API and the Explorer & Property Sheet API, among other topics.

I imagine JavaFX charts, and other cool looking JavaFX components, will be integrated into this application in future exercises too! 

You're very highly recommended to get the book, if you're interested in the NetBeans Platform in any way at all:

https://leanpub.com/migrating2nbp

Required reading for getting started with the above is "NetBeans Platform for Beginners":

YouTube: From Alice 3 to NetBeans IDE

Alice is a really cool tool to use as a teaching device, comparable to BlueJ and GreenFoot. Here you're shown how to map an Alice project to a NetBeans project, i.e., Java objects are generated from your Alice objects, and the flow of the Alice project is mapped to a Java class, all of which is packed into a Java project in NetBeans IDE. A handy plugin created by the Alice team makes all this possible:

JavaOne 2014 Afterglow and Feedback

This year JavaOne officially started with a technical keynote in the Moscone center. There were no great, breaking news, but in an open ecosystem it is hard to keep anything secret.The keynote was a bit too formal and the most interesting part was postponed to the community keynote at Thursday.

Unofficially JavaOne started with the NetBeans Party at Saturday which was crowded and a perfect place to ask NetBeans questions or give feedback to the engineers.

The technical content was excellent. I spent 14h at the first both days (8 A.M - 10 P.M.) and really enjoyed all sessions. There was appreciation event at Wednesday (which I did not attended and preferred hacking in hotel). No BOFs were delivered at Wednesday or Thursday.

The community keynote at Thursday was excellent:

  1. James Weaver @JavaFXpert was a great moderator. Professional, funny and engaging.
  2. Intel joins OpenJDK
  3. @johanvos ports JavaFX on android and wins Duke Choice Award
  4. RoboVM presents JavaFX on iOS
  5. Johan Vos and RoboVM will join forces and deliver Java 8 (JavaFX) with Lambdas on both platforms. http://javafxports.org
  6. http://dukescript.com (a Java -> JavaScript bridge) also wins the Duke Choice awards
  7. James Gosling explains the early days of Java.
  8. There was a twitter Q&A with top engineers. #1qa was top 7 trending hashtag in USA.
  9. The JavaOne video is nice.

Also the JavaFX related sessions were very popular. The session Productive JavaFX was very well attended. I got lots of specific questions from the project, so JavaFX seems to gain momentum on desktop. I got the same feedback from other speakers.

JavaOne was really good, there was no dead time, content was compressed and the attendees very passionated. There were also more attendees than last year. I got lots of questions between the sessions. The organization was good, the food was better than last and in Parc 55 there was always enough coffee. Only the Starbucks at Hilton was constantly overloaded...

Check my twitter account for pictures: https://twitter.com/AdamBien.

The only suggestion: BoFs at Wednesday would be nice as an option for the appreciation event. Also I missed more sessions delivered by Oracle speakers--I would like to hear more from the core Java / JavaEE committers.

In case my sessions get accepted -- see you next year!

Reflections on JavaOne 2014 by the NetBeans Community

NetBeans Day 2014 was even more spectacular than in previous years. Demo-driven lightning talks on key features, in particular the native integration of Maven, and the seamless deployment, debugging, and profiling of IoT embedded devices via Java and NetBeans, to packed out rooms, defined the day, with a lot of chatter in the corridors in between the sessions.
