Lifecycle extensions

The lifecycle extensions in Maven allow you to customize the standard build behavior. Let's take a look at the org.apache.maven.AbstractMavenLifecycleParticipant class. A custom lifecycle extension should extend from the AbstractMavenLifecycleParticipant class, which provides the following three methods that you can override:

• afterProjectsRead(MavenSession session): This method is invoked after all the Maven project instances have been created. There will be one project instance for each POM file. In a large-scale build system, you have one parent POM and it points to multiple child POM files.

• afterSessionEnd(MavenSession session): This method is invoked after all Maven projects are built.

• afterSessionStart(MavenSession session): This method is invoked after the MavenSession instance is created.

Let's try out the following example:

package com.packt.lifecycle.ext;

import org.apache.maven.AbstractMavenLifecycleParticipant;
import org.apache.maven.MavenExecutionException...
