Add support for Kotlin

[smwhit]

I've tried cover-agent against kotlin code and it doesn't seem to work. Can support be added?

I get:
cover_agent.CoverAgent - INFO - Current Coverage: 0%
then later

cover_agent.UnitTestGenerator - INFO - Running test with the following command: "./gradlew clean test jacocoTestReport"
cover_agent.UnitTestGenerator - INFO - Test did not increase coverage. Rolling back.`

I also have java code in this project and it works fine if I point cover-agent at the java files.

Hi @smwhit. Thanks for filing the issue. Any chance you can point us to an open source repo that we can use to test this out?

Hi @EmbeddedDevops1 - this should do it https://github.com/smwhit/cover-agent-kotlin-testing. Command line I am using for java and kotlin are in the readme.

你可能需要针对.kt单独做一个判断，因为kotlin的package没有;，className没有public
