Look at the jakarta-commons/logging module. I implemented a little
mechanism for excluding sources:
<build>
<sourceModifications>
<sourceModification>
<className>java.util.logging.Logger</className>
<excludes>
<exclude>**/Jdk14Logger.java</exclude>
</excludes>
</sourceModification>
</sourceModifications>
</build>
So what that does is exclude the Jdk14Logger source file if the
java.util.logging.Logger class isn't present.
