Trying to understand build project [message #661657]

Google searches haven't yielded a comprehensive answer. I'm simply trying to understand exactly what Project -> Build All does. I have >10 interdependent projects in my workspace. We have a maven build script that use to build the workspace after checking out the projects. It's my understanding that we also need to do a Build All from within eclipse.
Sometimes Build All completes, but more often I get an Out of Memory error. Any explanation of what exactly Build All does would be greatly appreciated.

Hi Bob,

Build all triggers the build of all the projects which are active in your workspace.So if you have large number of resources with too many buildable resource sometime OOME excpetion is thrown because building is a memory intensive operation.

Generally Building is also done in a separate UI job.Build All generally appears when Build automatically off.So you can have your Build automcatically turned on so that live builds happen rathen than the need of bulk build.

i think this article also nicely surmises the Eclipse build basics..

cheers,
Saurav
