We finally made the build for the e4 tools as simple as possible. Just can now build the e4 tools which a simple “mvn clean install”. For the exact commands, please see Building Eclipse tutorial.
I think it is important to make the Eclipse build process as simple as possible and I think it is great that the build process for the e4 tools are now as simple as it can get.
See Bug report for the details on the fix. Many thanks to Paul Webster, Thanh Ha and Markus Kuppe for contributing this fix.
