Scala specs target fialed to compile

[zyzheng]

I have tried to run ./pants goal compile on a scala specs target, but the compilation failed. Here's the trackback:

Traceback (most recent call last):

AttributeError: 'ScalaTests' object has no attribute 'java_sources'

Line 226 of jvm_dependency_analyzer.py contains the following code, which I believe is the cause to this problem:

225      elif target.is_scala:
226        return any(t in targets for t in target.java_sources)

ScalaSpecs are now removed. Use JavaTests instead.
