Conditional Javadoc Generation in Maven

Generating Javadoc at each build process can be very time consuming and pretty unnecessary. One can tackle this issue by moving Javadoc generation in a profile in the pom.xml:

<profiles>
  <profile>
    <id>JavadocGeneration</id>
    <build>
      <plugins>
        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-javadoc-plugin</artifactId>
          <version>2.8.1</version>
          <executions>
            <execution>
              <id>attach-javadocs</id>
              <goals>
                <goal>jar</goal>
              </goals>
            </execution>
          </executions>
        </plugin>
      </plugins>
    </build>
  </profile>
</profiles>

The above create a profile called JavadocGeneration. The Javadoc will be generated if and only if it is invoked:

mvn groupId:artifactId:goal -P JavadocGeneration
