Description

Attaching a zip that contains the example to reproduce the issue.

The scenario is this: From my Ant script, I am executing a groovy script (One.groovy), which depends on another script, Two.groovy (which has a compilation error - it refers to a non-existing class FFile).

The problem is that instead of telling me anything about FFile class's non-existence, the groovy compiler gives a not-so-useful error message that looks like below:

...\bug_report\build.xml:11: 

BUG! exception in phase 'semantic analysis' in source unit '...\bug_report\src\One.groovy' 

The lookup for Two caused a failed compilaton. There should not have been any compilation from this call.

It'll do better to include some information about the underlying exception.

"BUG! exception in phase 'semantic analysis' in source unit '...\One.groovy'" is not much use.
