According to the API, when creating a JAR which contains compile time an Annotation Processor it should follow the following structure.
uk --foo ----bar ------SomeAnnotationProcessor META-INF --services ----javax.annotation.processing.Processor And the javax.annotation.processing.Processor file contains the following line uk.foo.bar.SomeAnnotationProcessor If a META-INF/services/javax.annotation.processing.Processor is detected on the class path by the compiler it will try locate the Processor listed within. This JAR I can build manually, and then add to the classpath for my other projects, and anytime a class is compiled which is Annotated by an Annotation handled by the Processor, the Processor is ran during the actual compilation process. This works brilliant and exactly as intended, however I can not build this structure with maven. when I do a "mvn package" I get the following error.... [INFO] Compilation failure error: Bad service configuration file, or exception thrown while constructing Processor object: javax.annotation.processing.Processor: Provider annotations.processing.processors.CodeAnnotationProcessor not found My maven structure is as follows: src --main ----java ------annotations --------processing ----------processors ------------CodeAnnotationProcessor.java ----------annotations ------------CodeAnnotation.java ----resources ------META-INF --------service ----------javax.annotation.processing.Processor Where the project includes the Annotation Processor, the Annotation handled by the processor, and the .Processor file which will be picked up by the 1.6 compiler. My maven POM looks like <project xmlns="http://maven.apache.org/POM/4.0.0"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd";> <modelVersion>4.0.0</modelVersion> <groupId>mygroup</groupId> <artifactId>annotations-processor</artifactId> <packaging>jar</packaging> <version>1.0.0</version> <name>annotations-processor</name> <url>http://maven.apache.org</url> <dependencies> <dependency> <groupId>com.sun</groupId> <artifactId>tools</artifactId> <version>1.4.2</version> <scope>system</scope> <systemPath>C:/Java/jdk1.6.0_10/lib/tools.jar</systemPath> </dependency> </dependencies> <build> <plugins> <plugin> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.6</source> <target>1.6</target> </configuration> </plugin> </plugins> </build> </project> Now this fails at COMPILE with "mvn compile" with the above directory structure. To me this looks like the META-INF/services/javax.annotation.processing.Processor is being added to the classpath during compile. This will then cause the compiler to think I am wanting to process annotations using the referenced processor and then looks for it, which it cant, because it does not exist. Is there a way to just exclude this file from the class path during the build? Or a "non hack" way of getting the file into the jar at the end without going through the compile process. I can build all this manually, or build with Maven and then manually add just the .Processor in using the jar tool at the end, but this is far from practical. I hope my explanation of the problem makes sense.
