Hi Andrew,
In my opinion you definitely run into a gradle bug here. The following
script should work with gradle, but unfortunately it doesn't:
====
buildscript {
repositories {
flatDir name: 'local repo', dirs:'/Users/andrew/.m2/repository'
}
dependencies {
classpath "org.foo:my-compiler-adapter:0....@jar"
}
}
apply plugin: 'java'
compileJava.options.compiler = "org.foo.MyCompilerAdapter"
====
could you raise a jira issue? Maybe Adam knows more about the problem
and can give you a hint for a workaround.
regards,
René
