I am having problems building an AspectJ project using the aspectj-maven-plugin

the project has only one aspect:

src/main/java/org/lightforge/config/ConfigurationAspect.aj

ConfigurationAspect.aj does some members introduction according to Ch5 of AspectJ in Action 2nd Ed.

I am using Eclipse with AJDT and set pom.xml according to http://mojo.codehaus.org/aspectj-maven-plugin/

Although, when I run Maven install (Run As -> Maven Install), apparently aspectj-maven-plugin:compile is never executed.

Following is my pom.xml:

<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/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>lightforge</groupId> <artifactId>lightforge-config</artifactId> <version>0.0.6-SNAPSHOT</version> <name>lightforge-config</name> <dependencies> <dependency> <groupId>commons-configuration</groupId> <artifactId>commons-configuration</artifactId> <version>1.9</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.6</version> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjrt</artifactId> <version>1.6.11</version> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjtools</artifactId> <version>1.6.11</version> </dependency> </dependencies> <build> <pluginManagement> <plugins> <plugin> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.6</source> <target>1.6</target> </configuration> </plugin> <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>aspectj-maven-plugin</artifactId> <version>1.4</version> <configuration> <outxml>true</outxml> <ajdtBuildDefFile>build.ajproperties</ajdtBuildDefFile> <verbose>true</verbose> <aspectDirectory>src/main/java</aspectDirectory> </configuration> <executions> <execution> <goals> <goal>compile</goal> </goals> </execution> </executions> </plugin> </plugins> </pluginManagement> </build> </project>

This is my build.ajproperties:

src.includes = src/main/java/,\ src/main/resources/,\ src/test/java/,\ src/test/resources/ src.excludes = src/main/resources/**,\ src/test/resources/**

Finally, this is the Build Log:

  • Does this work when you run on the command line, eg mvn install? Commented Jul 29, 2013 at 15:49

Jon, Not sure if you got your answer and for reasons I cannot explain, removing the pluginManagement tag around the plugins seems to work.

Wow, this solved my problem, thanks! I started with a POM generated by Roo that contains the "pluginManagement" tag. Not sure why removing this tag helps.
pluginManagement define plugin configuration but doesn't apply them. If you need those plugin enabled in a pom, it must be applied outside the plugin management section, but style could be defined in it. it is especially useful when having multimodules project

You have to disable maven-compiler-plugin so that ajc compiler is used and not javac:

 <plugin> <artifactId>maven-compiler-plugin</artifactId> <version>2.5.1</version> <executions> <execution> <id>default-testCompile</id> <phase>none</phase> </execution> <execution> <id>default-compile</id> <phase>none</phase> <goals> <goal>compile</goal> </goals> </execution> </executions> </plugin>

OK...two things first that are not related to your problem:

  1. There's no need to use a build.ajproperties file. This is calculated automatically.
  2. You'll probably want to add a testCompile goal to the executions, otherwise your test classes won't be woven.

The answer lies with the fact that you are using AspectJ with ITDs, but the maven compiler runs before the AspectJ compiler and fails (because ITDs have not been woven). It doesn't look like there is a clean answer, but have a look at this question:

How do I disable the maven-compiler-plugin?

I never followed up and tried all of the solutions suggested there, but I do know that the following would work in single-pom scenario:

  1. <aspectDirectory>src/main/java</aspectDirectory> to <aspectDirectory>src/main/aspect</aspectDirectory>
  2. move all source files from src/main/java to src/main/aspect (or at least move the files that rely on the ITDs being woven).

Thanks four fast respose. Unfortunately, it did not work. Now I see the "BUILD SUCCESS" message, though the aspectj-maven-plugin is not executed and the .jar only content is the META-INF directory.
Please find the project layout, pom and log in the following address: link
