Mojo's AspectJ Maven Plugin

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>1.9.7</version>
    </dependency>
    ...
  </dependencies>
  ...
  <build>
    <plugins>
      <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>aspectj-maven-plugin</artifactId>
        <version>1.15.0</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 1.9.7, 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>${aspectj.version}</version>
    </dependency>
    ...
  </dependencies>
  ...
  <build>
    <plugins>
      <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>aspectj-maven-plugin</artifactId>
        <version>1.15.0</version>
        <dependencies>
          <dependency>
            <groupId>org.aspectj</groupId>
            <artifactId>aspectjtools</artifactId>
            <version>${aspectj.version}</version>
          </dependency>
        </dependencies>
