I have this source:
/**
* Goal which runs ant and then adds some path to the compile source root
list
*
* @goal run
* @phase generate-sources
* @description Run ant and then add a folder to the list of places that hold
* code to compile
*/
public class AntRunAddGenerateMojo extends AntRunMojo {
/**
* The Maven project.
*
* @parameter expression="${project}"
* @required
* @readonly
*/
private MavenProject project;
/**
* Where the source files were put by the ant task
*
* @parameter expression="${project.build.directory}/generated-sources/java"
* @required
*/
private String compileSourceRoot;
public void execute() throws MojoExecutionException {
getLog().info("enter execute()");
super.execute();
getLog().info("add compileSourceRoot: " + compileSourceRoot);
project.addCompileSourceRoot(compileSourceRoot);
getLog().info("exit execute()");
}
}
And I get this error:

I have no idea how to start looking at this. Do you have any strategies for
me?
Thanks.
