Hi Rene,
Apologies for not getting back to you sooner on this, but I have tried
what you said and it still does work. My compiler adapter jar is not
being added to the classpath in the right way.
I am trying something slightly different now. Since it looks like the
JavaPlugin uses ant under the covers, I am now setting the
build.compiler property through the command line:
gradlew -Dbuild.compiler=org.foo.MyCompilerAdapter compileJava
And using the following script (the compiler adapter jar is now
installed in my local maven repo
====
buildscript {
repositories {
flatDir name: 'local repo', dirs:'/Users/andrew/.m2/repository'
}
dependencies {
classpath "org.foo:my-compiler-adapter:0....@jar"
}
}
apply plugin: 'java'
====
When I execute the script, I get the following class not found exception:
...
* What went wrong:
Execution failed for task ':compileJava'.
Cause: Class not found: org.foo.MyCompilerAdapter
==========
What this is saying to me is that:
1. The JavaPlugin is triggering a java compiler through ant.
2. The -Dbuild.compiler property on the command line is correctly
causing the underlying ant execution to look for the compiler adapter.
3. The compiler adapter jar is being found in the maven repo
(otherwise I would have gotten a dependency exception).
4. But, the compiler adapter is still not on the ant classpath.
I have tried all sorts of variations of the script above (including
editing the gradlew script), but I can't seem to get the last piece
working. Do you have any further ideas on how to get this working?
I am starting to think that this is a bug. At the very least, the
documentation could be clearer on how to get this working. Should I
raise a bug for this? I can attach the sample project and add the
compiler adapter to a publicly available maven repo.
Thanks. I appreciate your help.
