Eclipse Java Build Directory

Question

Something driving me crazy - I have autobuild set in java eclipse ide and its building to a JAR apparently. Where is the output directory??

I don't see any build folders or anything in the project home folder.

Thanks, Kidovate

Solution 1

How are you examining the project folder? Many of the Eclipse navigation views filter out output folders. Take a look at your project directory with you OS file system browser instead.

The java output directories are configured via Project Properties -> Java Build Path. You can go to that page to see what folders are being currently used.

Note that Eclipse java build does not generate a jar. It generates a directory of classes. To generate a jar, you have to invoke File -> Export -> Jar File wizard or use an external script like ant or maven.

Solution 2

By default this is bin/ sub-directory of your project's directory, bin/classes will contain .class files, bin/ itself will contain .jar if you build it explicitly (e.g. via File/Export...). If you have m2eclipse installed and this is maven project then target directory will be target/.
