Jandex Plugin for Apache Maven

Full documentation can be found at: http://wildfly.github.io/jandex-maven-plugin

Basic Usage

<build>
  <plugins>
    <plugin>
      <groupId>org.jboss.jandex</groupId>
      <artifactId>jandex-maven-plugin</artifactId>
      <version>1.2.3</version>
      <executions>
        <execution>
          <id>make-index</id>
          <goals>
            <goal>jandex</goal>
          </goals>
          <!-- phase is 'process-classes by default' -->
          <configuration>
            <!-- Nothing needed here for simple cases -->
          </configuration>
        </execution>
      </executions>
    </plugin>
  </plugins>
</build>

This configuration will index all .class files in your target/classes directory, and write the index to target/classes/META-INF/jandex.idx.

Advanced Usage

If you need to process more than one directory of classes, you can specify multiple fileSets like this:

<build>
  <plugins>
    <plugin>
      <groupId>org.jboss.jandex</groupId>
      <artifactId>jandex-maven-plugin</artifactId>
      <version>1.2.3</version>
      <executions>
        <execution>
          <id>make-index</id>
          <goals>
            <goal>jandex</goal>
          </goals>
          <!-- phase is 'process-classes by default' -->
          <configuration>
            <fileSets>
              <fileSet>
                <directory>${project.build.directory}/generated-classes/foo</directory>
              </fileSet>
              <fileSet>
                <directory>${project.build.directory}/generated-classes/bar</directory>
              </fileSet>
            </fileSets>
          </configuration>
        </execution>
      </executions>
    </plugin>
  </plugins>
</build>

To turn off processing for target/classes, specify the following configuration:

<processDefaultFileSet>false</processDefaultFileSet>

For any fileSet, you can also fine-tune the classes that are processed using the following options:

<fileSet>
  <directory>${project.build.directory}/somedir</directory>
  <!-- included globs -->
  <includes>
    <include>**/indexed/*.class</include>
    <include>**/idxd/*.class</include>
  </includes>
  <!-- excluded globs -->
  <excludes>
    <exclude>**/*NotIndexed.class</exclude>
  </excludes>
  <!-- normally true, this excludes things like the CVS/ and .svn/ directories, log files, etc. -->
  <useDefaultExcludes>false</useDefaultExcludes>
</fileSet>
