> add support for annotation processing javac option -processorpath
> cf. http://download.oracle.com/javase/6/docs/technotes/tools/windows/javac.html#processing
> while not supported, annotation processor classes have to be supplied via compile classpath.
> annotation processor dependencies (e.g. database, xml processing, ...) might not be wanted
as project dependencies or event be in conflict with them.
> as a workaround I have attached new ProcCompilerMojo, where I tried to implement processorpath
support
> 1) via a new configuration option: dependency resolution is done with bits of code I
copied from other maven classes like ProjectBuilder, ...
> {code}
> <configuration>
> 	<proc>only</proc>
> 	<processorpath>
> 		<dependency>
> 			<groupId>org.slf4j</groupId>
> 			<artifactId>slf4j-jdk14</artifactId>
> 			<version>1.5.6</version>
> 		</dependency>
> 		<dependency>
> 			<groupId>com.example</groupId>
> 			<artifactId>annoproc</artifactId>
> 			<version>1.0.0</version>
> 		</dependency>
> 	</processorpath>
> </configuration>
> {code}
> 2) (unused) via plugin dependencies: I basically make use of ProcCompilerMojo classloader
urls. This variant is quite "dirty". it adds unnecessary maven plugin jars to annotation processor
classpath and unnecessary annotation processor jars to compiler-plugin classpath
