We transform plugins classpath, TestKit classpath and buildscript classes separately. 
Plugins classpath, TestKit classpath are transformed via Artifact transform, base logic is implemented in [BaseInstrumentingArtifactTransform.java](https://github.com/gradle/gradle/blob/master/subprojects/core/src/main/java/org/gradle/api/internal/initialization/transform/BaseInstrumentingArtifactTransform.java).
