Workflow/pipeline support

[qrsty]

This PR adds support to run the unity3d plugin via pipeline scripts.

e.g.

node('unity') {
    def name = 'your_unity_install_name'
    def args = '-quit -batchmode -executeMethod MyClass.MyMethod'
    unity3d unity3dName: name, argLine: args
}

Contains support for the snippet generator:

This required bumping up the required jenkins plugins dependency version to 1.642.3. This changed some unit tests to require MasterToSlaveCallable because of different security restrictions.

A dependency to org.jenkins-ci.plugins.workflow.workflow-step-api has been added.

This mainly adds the Unity3dBuilderStep class and changes Unity3dBuilder to implement the SimpleBuildStep interface. This changes the perform method to require a Run<?, ?> instead of an AbstractBuild<?, ?>. A Run does not have access to a workspace, so a FilePath is injected for alternative access to paths and Computers.

I've moved out some methods to a helper class for use by the Unity3dBuilderStep class.

The only issue I have left is a compiler warning that I can't seem to get rid of:
Warning unknown enum constant edu.umd.cs.findbugs.annotations.When.ANYTIME Unity3dBuilder.java C:/Repos/unity3d-plugin/src/main/java/org/jenkinsci/plugins/unity3d/Unity3dBuilder.java

It seems to be an issue with the com.google.guava dependency version being updated. This had to be raised due to the InjectedTest suite changing from the 1.642.3 jenkins plugins version.

Let me know if there's anything I should take a look at or improve.

Cool. Thanks a lot for the PR. I'll look at it in a few days. I have to setup a 2.0 with workflow setup.

Awesome work, finally there is a working pipeline support. But since your changes variables in the installation dir are not getting parsed anymore.

FATAL: The configured Unity3d installation directory (${PROGRAMFILES}\Unity5.4.0f3) is not recognized as a Unity3d home directory. Remember that the plugin adds per-platform suffixes and is searching for the executable at ${PROGRAMFILES}\Unity5.4.0f3\Editor\Unity.exe.

[qrsty]

Where is ${PROGRAMFILES} defined? How are you specifying the string for the path? The Groovy script should be able to parse environment variables with double-quoted or slashy strings.

I'm not sure where to access build variables for pipeline jobs, as the build type is now a Run<?, ?> instead of an AbstractBuild<?, ?>. A Run does not have a getBuildVariables() method.

The offending code is likely here. Any fixes are appreciated.

${PROGRAMFILES} is a default windows environment variable.

The upper picture is a screen from the original plugin, the lower with your modifications. The variables also do not get parsed in the tool configuration anymore. I will have a look on this issue maybe I can fix it.

Have you had time to look into this yet?

looks good AFAICT

Would actually be really neat to have to change in there ;)
