Installation Error

[suchad]

Cloning the current master branch for hydrograph is not yielding the tool to work, At Step 1 of build, a set of test cases are failing(probably because of missing classes) and the same is the error that we are getting during the installation. Can someone confirm if the current master represents the true copy of product code? Secondly, Is this the only place to raise questions like this?
Install Error:

• What went wrong:
  Execution failed for task ':install'.

Update:
Could it be possible that some of the environment variables are causing it? Is there a suggestion as with what minimum value of standard variables, Hydrograph will work? (I have lot many automation tools installed which use these variables but I am not ideally a Java guy, so appreciate anyone's support on this)
