By default, the plugin provide a DefaultShader implementation but with version 1.6 you can use your own implementation.
Create a standard Maven project with your implementation.
Dependency to Plexus annotations <dependency> <groupId>org.codehaus.plexus</groupId> <artifactId>plexus-component-annotations</artifactId> <version>1.5.5</version> </dependency> Create your Shader @Component( role = Shader.class, hint = "mock" ) public class MockShader implements Shader { // implement the interface here } // Use the plexus component metadata plugin in your job to generate Plexus metadata <plugin> <groupId>org.codehaus.plexus</groupId> <artifactId>plexus-component-metadata</artifactId> <version>1.5.5</version> <executions> <execution> <goals> <goal>generate-metadata</goal> </goals> </execution> </executions> </plugin>
Assuming your project has coordinate org.foo.bar:wine:1.0, you must add it as a dependency of the shade plugin.
<project> ... <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-shade-plugin</artifactId> <version>1.7.1</version> <dependencies> <dependency> <groupId>org.foo.bar</groupId> <artifactId>wine</artifactId> <version>1.0</version> </dependency> </dependencies> <executions> <execution> <phase>package</phase> <goals> <goal>shade</goal> </goals> <configuration> <shaderHint>mock</shaderHint> </configuration> </execution> </executions> </plugin> </plugins> </build> ... </project>
Now the mojo will use your own implementation.
