Netbeans module development with JRebel

In [project]\nbproject\platform.properties add the following line

run.args.extra=-J-noverify -J-javaagent:e:/tools/jrebel/jrebel.jar -J-Drebel.log=true

Note:

• This requires a proper installation of jrebel in the path e:/tools/jrebel/
• Do not forget to generate a rebel.xml into the root of your classpath
• You have to compile the changed java source manually by Menu->Run->Compile file(“Compile-on-save” is not yet available for netbeans modules)
• There will be some OSGI-exceptions when running/debugging the application, but class reloading works properly.

Tested with NetBeans IDE 7.1 RC2 (Build 201111302200)+7.1, JRebel 4.5.3

Update: You can also have a look at Javeleon

Update 2: In maven-based nbms you can run modules the following way

• enable “compile on save”
• generate rebel.xml to /src/main using the context menu of jrebel (this way it will be copied to target/classes)
• alter the properties-section of the pom.xml like this
  

      <properties>
          <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
          <netbeans.run.params.ide/>
          <netbeans.run.params>-J-noverify -J-javaagent:e:/tools/jrebel/jrebel.jar -J-Drebel.log=true ${netbeans.run.params.ide}</netbeans.run.params>
      </properties>
  

• run the module the normal way – you will accounter some osgi-exception as mentioned above
• make changes to your classes and jrebel will pick it up like [207230] JRebel: Reloading class 'b2s.compare.clipboard.TextDiffer'.
• small issue: the jrebel-messages do not appear on the output-window – but in jrebel.log
