Error while building Jboss developer studio 9.1.0 Beta 2 from source - tycho

Question

I have downloaded jboss-devstudio-9.1.0.Beta2-src.zip and am building it from source.
However, the build is failing with the following error:
[ERROR] Failed to execute goal org.eclipse.tycho:tycho-packaging-plugin:0.24.0:package-plugin (default-package-plugin) on project com.jboss.devstudio.core: Execution default-package-plugin of goal org.eclipse.tycho:tycho-packaging-plugin:0.24.0:package-plugin failed: One of setGitDir or setWorkTree must be called. -> [Help 1]

So it is looking for a git repository in the directory, but I have downloaded source code zip.
Any ideas how I can resolve this error and proceed with the build?

This issue was fixed: https://issues.jboss.org/browse/JBDS-3598
Note that as of devstudio 10.x, sources are public so you can just fetch the latest from github and build from that.
https://github.com/jbdevstudio/jbdevstudio-product
Or for a specific release, you can download a zip of sources:
https://github.com/jbdevstudio/jbdevstudio-product/releases/tag/jbdevstudio-10.1.0.GA
