Log which class triggered errors in mojos

[chrylis]

I'm trying to upgrade from 1.6.1 to 1.6.2, and I'm running into "Unable to get a Groovy class from classpath." in the groovydoc goal. I suspect this is something to do with the modularization in 2.5 and it just wants a particular module I don't already have, but the error message would be much more helpful if it included which class produced the ClassNotFoundException.

I am making some progress with -X on my development machine, but this first cropped up in CI, where all I have is the standard log.

cf

GMavenPlus/src/main/java/org/codehaus/gmavenplus/mojo/GroovyDocMojo.java

Line 54 in 1292611

throw new MojoExecutionException("Unable to get a Groovy class from classpath. Do you have Groovy as a compile dependency in your project?", e);

Sorry for the late reply. I'd need to see some of your pom to figure out what's going on here. The stacktrace should already log the class it can't find. I'm not sure an easy way to parse the stacktrace to include the class in the regular exception message.

In this particular case, the log message is in the catch block for ClassNotFoundException e; the missing class is (in practice although not required by API contract) listed in e.message.

OK. I've added a change to log the message from the original exception.
