Gradle support for Java projects

[ljleppan]

Implement Gradle support for Java. Use AbstractJavaPlugin to handle all the busywork and call the tmc-junit-runner maven goal via Gradle to run tests, if possible.

See https://docs.gradle.org/current/userguide/embedding.html and https://docs.gradle.org/current/javadoc/.

Preferably do this in a way that allows for easy extraction of code for a dedicated Java-independent Gradle plugin at a later date.

I can try to do this one

Update: Having lots of troubles with creating the result.txt because all the solutions are maven-based atm. Have implemented the compiling for gradle projects and there is also tests for them. Should I keep going or create pr which contains some support for gradle projects (test evaluations are missing) so somebody else could also work with this?

So the problem seems to be that https://github.com/testmycode/tmc-maven-plugin/blob/master/src/main/java/fi/helsinki/cs/tmc/maven/TmcTestMojo.java this must be translated to gradle plugin

That Mojo seems to be doing essentially the same thing as AntPlugin#createRunResultFile(Path projectBasePath), so perhaps that would be a better starting point. The Mojo seems to contain loads of Maven specific code.
