maven-compiler-plugin resources not in classpath
I am trying to use maven to compile a java annotation processor. When you build a jar which contains an annotation processor you can put a file (META-INF/services/javax.annotation.processing.Processor) which contains one line per annotation processor. With this file in place you then only have to include the jar in the javac classpath to get it to process annotations, you do not have to mention it on the command line. Unforunately if you build your pom.xml to include this file under the resources tag, it gets included in the classpath, and then the compiler complains that the annotation processor it is compiling (the one mentioned in the file) does not exist, so it can not run it as an annotation processor so the compilation fails. So what I need is a means to add the file to the jar without adding it to the compiler classpath. Anyone got any suggestions.

Re: maven-compiler-plugin resources not in classpath
Hi David, If I understand the problem correctly, it will be solved by excluding META-INF/services/javax.annotation.processing.Processor file from your module resources (thereby preventing it from being put into the classpath). Please read http://maven.apache.org/pom.html#Resources for more information on how to do that.

I want it excluded from the compilation but included in the jar.

Hello David, Please review the maven-jar-plugin, specifically the includes parameter to the jar goal. http://maven.apache.org/plugins/maven-jar-plugin/jar-mojo.html#includes -jesse On Mon, Apr 6, 2009 at 9:47 AM, David Goodenough david.goodeno...@btconnect.com wrote: But will that not exclude it from the jar as well?

OK, I added:- plugin artifactIdmaven-jar-plugin/artifactId configuration includes includetarget/classes/*/include includeresources/*/include /includes /configuration /plugin and it only puts the META-INF/maven bits into the jar. The classes are under target/classes, and there is a META-INF under resources. What should I have done?
