Usage

This plugin weaves AspectJ aspects into your classes using the AspectJ compiler ("ajc"). There are typically two ways to package and use aspects in your Maven reactors; either as a standalone project where aspects and code are defined within the same Maven project - or as part of a multi-module Maven reactor where one/some project(s) contains aspects and other projects within the Maven reactor contain code using the aspects ("woven by the aspects").

Below follows a standard single-project usage example.

<project>
  ...
  <dependencies>
    ...
    <dependency>
      <groupId>org.aspectj</groupId>
      <artifactId>aspectjrt</artifactId>
      <version>1.8.2</version>
    </dependency>
    ...
  </dependencies>
  ...
  <build>
    <plugins>
      <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>aspectj-maven-plugin</artifactId>
        <version>1.7</version>
        <executions>
          <execution>
            <goals>
              <goal>compile</goal>       <!-- use this goal to weave all your main classes -->
              <goal>test-compile</goal>  <!-- use this goal to weave all your test classes -->
            </goals>
          </execution>
        </executions>
      </plugin>
      ...
    </plugins>
  <build>
  ...
</project>

Upgrading AspectJ

The frequency of releases of this plugin is lower than of AspectJ. If you want to use a different version of AspectJ than 1.8.2, you also need to upgrade the aspectjtools within the plugin.

<project>
  ...
  <properties>
    <aspectj.version>1.7.n</aspectj.version> <!-- specify your version -->
  </properties>
  
  <dependencies>
    ...
    <dependency>
      <groupId>org.aspectj</groupId>
      <artifactId>aspectjrt</artifactId>
      <version>${aspectj.version}</version>
    </dependency>
    ...
  </dependencies>
  ...
  <build>
    <plugins>
      <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>aspectj-maven-plugin</artifactId>

        <dependencies>
