Is this an internal Gradle problem

[Russel Winder-4]

I haven't build ADS using Gradle for a while so I just tried.  Clearly
there is something wrong, either a breaking change that I haven't
tracked in the build,gradle or a problem in Gradle.  I suspect the
former but the message doesn't give me much to go on :-(
       
        :compileJava
       
        FAILURE: Build failed with an exception.
       
        * Where:
        Build file '/home/users/russel/Repositories/Bazaar/Masters/ADS/build.gradle'
       
        * What went wrong:
        Execution failed for task ':compileJava'.
        Cause: org.gradle.api.tasks.util.FileSet cannot be cast to groovy.lang.GroovyObject
       
        * Try:
        Run with -S option to get the full (very verbose) stacktrace.
       
        * Exception is:
        org.gradle.api.GradleScriptException: Build file '/home/users/russel/Repositories/Bazaar/Masters/ADS/build.gradle'

You probably need to do a clean and then build Gradle (at least until we
have incremental compilation).

This is a fresh compile after a clean.

Actually it would be very helpful if someone could branch the Bazaar
branch and try it to see if the same result obtains.

        http://www.russel.org.uk/Bazaar/ADS

I just got the same result running Gradle against a branch new
branch :-(

It just struck me that you say Gradle doesn't yet have incremental
compilation.  I had thought that the whole point of the DAG was that
each and every file was checked separately for needing to be compiled
and that all import dependencies were also checked to ensure that
transitive dependencies on changed files were transmitted through.  If
this is not yet the case then it is likely that many people have been
working under a big misapprehension.

One of the biggest problems with Java compilation is that Javac is
basically useless at handling these issues and Ant and Maven (and Gant)
don't do anything extra.  This is where SCons wins hugely since it
handles all this very, very carefully.  This has to be Gradle's USP --
"no more always building from clean as with Ant and Maven".

Can I suggest that this be the blocking issue for 0.9?

I don't think that many people have this misunderstanding. The DAG  
contains task. The Java files are all compiled by one task. In this  
case it is the job of the compile task to be smart.

We offer incremental compilation (via the Ant depend task under the  
hood). At the moment you have to switch it on explicitly.

<compileTaskName>.options.useDepends = true

We might use this as the default for 0.9.

After 0.9 we are thinking about providing an own incremental compile  
implementation which would also catch some cases which are not covered  
by the Ant depend task. This would only work with Java 6. For Java 5  
users we would still delegate to Ant depend.

Unfortunately I could not check this out with bazaar 1.10. I have the  
Mac 2.0.1 Bazaar bundle but bzr --version still gives a 1.10.

Could you send a src zip?
