Usage

Example1

Sources will be generated into target/generated-sources/apt/main/java Test sources into target/generated-sources/apt/test/java Both directories will be added to the compilation path

<build>
  <plugins>
    <!-- Run annotation processors on src/main/java sources -->
    <plugin>
      <groupId>org.bsc.maven</groupId>
      <artifactId>maven-processor-plugin</artifactId>
      <executions>
        <execution>
          <id>process</id>
          <goals>
            <goal>process</goal>
          </goals>
          <phase>generate-sources</phase>
        </execution>
      </executions>
    </plugin>
    <!-- Run annotation processors on src/test/java sources -->
    <plugin>
      <groupId>org.bsc.maven</groupId>
      <artifactId>maven-processor-plugin</artifactId>
      <executions>
        <execution>
          <id>process-test</id>
          <goals>
            <goal>process-test</goal>
          </goals>
          <phase>generate-test-sources</phase>
        </execution>
      </executions>
    </plugin>
    <!-- Disable annotation processors during normal compilation -->
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-compiler-plugin</artifactId>
      <configuration>
        <compilerArgument>-proc:none</compilerArgument>
      </configuration>
    </plugin>

  </plugins>
</build>

Example2

Generating sources into src/main/generated directory. This strategy is good if you wish to check in your generated sources into your SCM. Run mvn generate-sources to generate the sources.

<build>
  <plugins>
    <plugin>
      <groupId>org.bsc.maven</groupId>
      <artifactId>maven-processor-plugin</artifactId>
      <executions>
        <execution>
          <id>process</id>
          <goals>
            <goal>process</goal>
          </goals>
          <phase>generate-sources</phase>
          <configuration>
            <!-- source output directory -->
            <outputDirectory>src/main/generated</outputDirectory>
          </configuration>
        </execution>
      </executions>
    </plugin>
  </plugin>
</build>

Example3

Running specific annotation processors only.

<build>
  <plugins>
    <plugin>
      <groupId>org.bsc.maven</groupId>
      <artifactId>maven-processor-plugin</artifactId>
      <executions>
        <execution>
          <id>process</id>
          <goals>
            <goal>process</goal>
          </goals>
          <phase>generate-sources</phase>
          <configuration>

            <processors>
               <!-- list of processors to use -->
               <processor>org.bsc.apt.BeanInfoAnnotationProcessor</processor>
            </processors>

          </configuration>
        </execution>
      </executions>
    </plugin>
  </plugin>
</build>

Example4

Passing options to processors

<build>
  <plugins>
    <plugin>
      <groupId>org.bsc.maven</groupId>
      <artifactId>maven-processor-plugin</artifactId>
      <executions>
        <execution>
          <id>process</id>
          <goals>
            <goal>process</goal>
          </goals>
          <phase>generate-sources</phase>
          <configuration>
           <!-- STANDARD WAY -->
            <compilerArguments>-Amyoption=TRUE</outputDirectory>

           <!-- NEW FEATURE FROM VERSION 2.0.4-->
           <options>
                <myoption>TRUE</myoption>
           </options>

          </configuration>
        </execution>
      </executions>
    </plugin>
  </plugin>
</build>
