问题
I have a plugin which generates sources under the target/generated-sources/wrappers directory. It's wired into the generate-sources phase like this:
<plugin>
<groupId>mygroupid</groupId>
<artifactId>myartifactid</artifactId>
<executions>
<execution>
<phase>generate-sources</phase>
<goals>
<goal>xml2java</goal>
</goals>
</execution>
</executions>
</plugin>
The problem is, when I use mvn deploy the .class files won't be placed in the jar. I see all the .java files there, but no .class.
I read all the issues around this problem, but couldn't figure out how to solve the problem. I'm using Maven 3.0.x.

The build-helper plugin indeed solved the problem. Thanks @Joe for the comment.
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>build-helper-maven-plugin</artifactId>
<executions>
<execution>
<phase>generate-sources</phase>
<goals>
<goal>add-source</goal>
</goals>
<configuration>
<sources>
<source>${project.build.directory}/generated-sources/wrappers</source>
</sources>
</configuration>
</execution>
</executions>
</plugin>

If you have written the plugin by yourself you can programatically add the path with the generated sources to the maven source paths.
@Mojo(name = "generate")
public class MyCodegenMojo extends AbstractMojo {
@Parameter(defaultValue = "${project}")
private MavenProject project;
@Override
public void execute() throws MojoExecutionException, MojoFailureException{
// your generator code
project.addCompileSourceRoot("path/to/your/generated/sources");
}
}
For example the raml-jaxrs-codegen plugin uses this technique. See RamlJaxrsCodegenMojo.java for more details.
