David Boden commented on MCOMPILER-66:
--------------------------------------
Adding <showWarnings>true</showWarnings> to my compiler plugin <configuration/>
results in:
* The Kind.NOTE print statements being output as [ERROR]
* Without the showWarnings, the statements don't get printed.
* The build fails (it succeeds when showWarnings=false), probably because
the NOTE messages have been artificially raised to ERROR level and Maven is
interpreting this as a build failure?
I'm using:
<artifactId>maven-compiler-plugin</artifactId>
<version>2.3.1</version>
I'm building this project:
http://immutablebean.googlecode.com/svn/ImmutableBeanExample
Hopefully you'll be able to check out this project, build it and change the
<showWarnings/> to recreate this error at will.
Here's the output I get with showWarnings=true:

> Compiler swallows messages from annotation processors
> -----------------------------------------------------
>
> Key: MCOMPILER-66
> URL: http://jira.codehaus.org/browse/MCOMPILER-66
> Project: Maven 2.x Compiler Plugin
> Issue Type: Bug
> Affects Versions: 2.0.2, 2.1
> Reporter: Evan Cowden
> Attachments: AnnotationProcessorMessagerBug.zip
>
>
> When using the annotation processor API to print messages through the
> javax.annotation.processing.Messager object, only messagesspecified by levels
> javax.tools.Diagnostic.Kind.ERROR and
> javax.tools.Diagnostic.Kind.MANDATORY_WARNING are displayed (and cause the
> build to fail). All other messages are swallowed.
> Note that while the attached JUnit test case is necessary to help expose the
> problem, passing it will not imply that the bug is fixed. The only way to
> confirm the fix (that I know of) is to examine console output.
