Plugin Rewrite for Gradle 6+

[Azurelol]

Description

Redesigns the plugin for newer version of Gradle; attempts to simplify the architecture.
To be compatible with newer gradle versions we decided to refactor the whole plugin.
The old architecture of the plugin was quite complex to support batchmode calls from the extension.
This feature is gone as it wasn't really used or had any benifits. The support for unity package creation
is also gone since building and releasing them is no longer a prio.

Changes

• plugin structure
• task API
• unity package creation support

I had a short look and found two issues from my setup (macOS)

I would also like to see that all *IntergrationTest classes are renamed back to *IntegrationSpec. I see these tests more like specifications than plain test files.

I needed to add these lines since I don't have an active Unity license. So we must trick the system into thinking we have one.

    def setup() {
        //setup fake license dir so we don't delete actual licenses
        def licenseDir = File.createTempDir("unity","testLicenseDir")
        createFile("testLicense", licenseDir)
        buildFile << """
        unity {
            licenseDirectory.set(new File("${escapedPath(licenseDir.path)}"))
        }
        """.stripIndent()
    }

Done.

These two examples error on macOS because the logfile path it prodocues is /${testTaskName}.log which is not writeable. I couldn't find the logic where the full path gets combined.
