JaCoCo with Maven multi-module or Gradle multi-project builds

[derekm]

Describe the bug
coverageLocations can be multiple values, but JACOCO_SOURCE_PATH can only contain one value.

In a Java build that produces multiple jars, I need a different JaCoCo source path per coverage location.

Version of codeclimate-action you're using
v2.5.7

Expected behavior
I should be able to specify the source paths for each coverage location.

Additional context
This may need to be reported upstream here: https://github.com/codeclimate/test-reporter

Hi guys! I'm having the same issue. Here you can see an example of the error, and this is the PR where I am adding the action.

Looking at the codeclimate test-reporter's code reveals that a whitespace separated list is expected as input:
codeclimate/test-reporter@b2ae857

Unfortunately, this action does not support globbing for the environment variables (I'm guessing that it's not possible to re-set an environment variable from within the running action?), so while I can use tree globbing "**" for the coverageLocations, I have to explicitly list every modules source directories...
