Jitpack build unavailable

[cuong-tran]

Latest version v0.91.2 isn't available in JitPack store probably due to failed git clone.

Jitpack is not currently a supported publishing method. It appears to fail (at least for 0.91.1) because the build requires signing, but there is no gnupg key to sign. I've pushed a change to the build script that should skip signing if run on jitpack
