[gradle-dev] The ASM Opcode problem

[Russel Winder]

Tom prompted me to be a little more detailed about the actual issue:

        Build failed with an exception.
        Run with -f option to get the full (very verbose) stacktrace.
        
        Build file 
'/home/users/russel/Repositories/Bazaar/Branches/ModeConsole/build.gradle'
        
        Execution failed for task ':compile'.
        Cause: org/objectweb/asm/Opcodes
        
        Exception is:
        org.gradle.api.GradleScriptException: Build file

So the problem is clearly that the relevant ASM jar is not in the class
path.  This means putting teh groovy jar as opposed to the groovy-all
jar as the groovy jar does not work even if unmanagedClasspath contains
all the jars from GROOVY_HOME/lib.

This is not the real problem though, the real problem is that the error
message is very poor.  The second real problem is how to deal with
getting the right jars on the right classpath.

I shall have to give up for now, mostly because I have to write a talk
for tomorrow evening, but also because it's late ;-)
