This is the process that's usually followed to create a full build of everything
Build all components/projects
This build will compile all of the sub-projects and components and results in an archived update site that you can install directly into your Eclipse IDE. The build is designed to do all of the getting of source code from the SVN repository at dev.eclipse.org, so this build will only function if you are online. If you have ideas for an offline build, then please consider submitting a Bugzilla with your ideas, or better still, patches.
The execution is straightforward - simply check out the STP toplevel build and call ant to kick things off. You will need ant version 1.7.1, because the build takes advantage of a new task that is only available starting at that version.
$ svn co http://dev.eclipse.org/svnroot/stp/org.eclipse.stp.build/build/trunk build $ cd build $ ant -Dbase.directory=/somewhere/myBuild -Dplatform=/somewhere/eclipse build build.site
That should be all there is to it! After the build has completed, you will have the update site archived as a zip file in the /somewhere/myBuild directory. The base.directory must be an absolute path. The platform should be set to where you have all the dependencies in place. You will find a list of the dependencies, and how to create a platform installation at this wiki entry.
