How do I install the Java support into the Ruby NetBeans IDE?
If you download NetBeans Ruby IDE only, i.e. without Java support you might install it later through Plugin Manager (Menu | Tools | Plugins). Just select Java plugin in the Available Plugins tab as shown in the screenshot. You might wish to install e.g. Java Debugger, Java Profiler, etc. as well.
Manual Java cluster installation (using dev build)
- Download the latest Ruby IDE as described in How do I get the Continuous Builds?
- Download the latest Java cluster from the same place, from module cluster folder -> netbeans-hudson-trunk-buildnumbe-java.zip
- Unzip content of the Java cluster zip (java2 folder) into the unzipped Ruby IDE, so the final structure will look like (note the java2 there):
$ ls -1 netbeans bin/ CREDITS.html DISTRIBUTION.txt etc/ gsf1/ ide10/ java2/ LEGALNOTICE.txt LICENSE.txt moduleCluster.properties nb6.5/ netbeans.css platform9/ README.html ruby2/ THIRDPARTYLICENSE-generated.txt THIRDPARTYLICENSE.txt webcommon1/ websvccommon1/
