Hi Dirk,
My second problem is with git branches. My problem here is that I wanted to use the cloudstack version 4.13.1 as base, for this reason I checkout the 4.13.1 branch, but the build process goes wrong with a couple of errors, after this I checkout the master and revert it to the commit b2ffa3e<https://github.com/apache/cloudstack/commit/b2ffa3efa58a1569dbaa8a34f723756926e22820>. But the build process still didn’t work. Then I thought that I have problems with my dev environment and test the build process with the official release, but this works fine. So now I’m a little bit confused. What should I do, when I want to use a specific code base version? I had similar problems when I tried to build tags, but I can't quite remember how I solved them. Note that there is no 4.13.1 branch, only 4.13. There is a tag for 4.13.1.0 though. Perhaps you should try again with the HEAD of 4.13? Your best option will probably be to clean out any build leftovers and maybe even your Maven cache, then try again. There may also be subtle differences in building with IntelliJ and from the command line. Regards, Gregor
