Package org.jboss.maven.plugins.injection

Class BytecodeInjectionMojo

java.lang.Object

org.apache.maven.plugin.AbstractMojo

org.jboss.maven.plugins.injection.BytecodeInjectionMojo

All Implemented Interfaces:

org.apache.maven.plugin.ContextEnabled, org.apache.maven.plugin.Mojo

public class BytecodeInjectionMojo
extends org.apache.maven.plugin.AbstractMojo

Used to inject resolved expression values into compiled bytecode.

TODO : add checks as to whether the injection is needed to avoid file timestamp changes. Basically we should skip the injection if the class file field is already the injection value...
