This post is mostly obsolete: See http://wp.me/pIpWO-n0 for an updated version.
Based on a previous post https://benkiew.wordpress.com/2011/12/28/netbeans-module-development-with-jrebel/ i made a small video screencast to show how to use JRebel to improve your productivity when developing NetBeans modules.
1. Preconditions and setup
- NetBeans 7.1.2/7.2.x installed (should work also with other version, but only these two were tested)
- a valid installation of JRebel > 4.5.x (tested with 4.5.x, 4.6, 4.6.2, 5.0.0)
- a valid license for JRebel – can also be the free social one – has to be configured in the JRebel configuration wizard
- JRebel Netbeans Plugin 1.2 installed (use the update center) – required for debugging JRebel-instrumented code and generating rebel.xml
- Change shortcut for “compile” to CTRL-S (Compile includes saving) – the equivalent to eclipse “Build automatically” or NetBeans “Compile on save” (Because “compile on save” is not yet available for module development projects)
2. Step by step
- Follow the instructions to generate a sample project @ http://platform.netbeans.org/tutorials/nbm-code-generator.html
- Select “
Generate rebel.xml” in the context menu of your project, select the root path of your sources - Add the following line to \nbproject\platform.properties (can be found in the Projects-panel named as “NetBeans Platform Config”)
run.args.extra=-J-noverify -J-javaagent:d:/tools/JRebel/jrebel.jar -J-Drebel.log=true
These parameters are taken from the offical JRebel documentation http://manuals.zeroturnaround.com/jrebel-reference-manual/server.html#server-4.6.1 - Run the project -> a new NetBeans instance should be opened
Note the output of the activated JRebel plugin in the output window of the development:
JRebel: Starting logging to file: D:\tools\JRebel\jrebel.log

- Ignore the OSGI-exceptions (JRebel does not yet officially supports nbm-development) – UPDATE: this seams to be fixed in JRebel 5.0.0
- Change the method content, change fields, do some refactoring …
- CTRL-S for compiling including saving (see setup above)
- execute the action in the target IDE again -> JRebel will reload the code
