Description

When failOnError is set, Groovyc currently logs the error at info level and then throws a BuildException. Unfortunately, when running ant with the quiet flag (ant -q), this means that compilation errors aren't displayed, and you're left with a mysteriously failed build with no reason provided. Javac errors are logged at the error level (and visible with -q), so groovyc should be too.

Strangely, compilation failures are logged at the error level if failOnError is false. I'm uncertain as to why it's currently the way it is. Perhaps the thrown exception used to include the error message and would be presented to the user, but this isn't the case anymore.
