Fix jfrog dependency error on gradle install

[heralden]

When running ./gradlew install it gives this error:

* What went wrong:
A problem occurred configuring project ':bio-source-humanmine-static'.
> Could not resolve all artifacts for configuration ':bio-source-humanmine-static:classpath'.

It doesn't seem like these dependencies are actually used by humanmine-static and removing them causes gradle install task to succeed.
