java.lang.AssertionError: PolyCollector: mismatched type kinds

[GoogleCodeExporter]

Caused by this:

    import java.io.File;
    import static com.google.common.base.Preconditions.checkNotNull;

    class Test {
        public void test() {
            File file = null;
            checkNotNull(file).getName();
        }
    }

Besides the underlying error (java.lang.AssertionError: PolyCollector: 
mismatched type kinds), this is another example of an error that fails the 
maven build without any messages (which is quite confusing).  Is it possible to 
report these errors in some way that maven compiler plugin will display?

Thanks,
Trask

Hi Trask, Thanks for the report! This is currently fixed in our private 
type-variable repository which we plan to merge within the next couple of 
releases.

As for getting more information out of maven, try removing 
<verbose>true</verbose> from the maven-compiler-plugin configuration. It seems 
that when verbose is true, maven doesn't try to parse the exception error 
messages. I'll be updating the manual to reflect that change.
