I’m using the mojo-executor library to call a number of Maven plugins from within

  • 0

I’m using the mojo-executor library to call a number of Maven plugins from within another Maven plugin.

However, I can’t find any way to specify dependencies on the plugins as I’m invoking them. This is an issue for the maven-assembly-plugin, where I need to add an assembly descriptor file as a dependency. Adding the dependency at another level doesn’t seem to get the descriptor file onto the plugin’s classpath.

Any idea if this is possible, or if mojo-executor could be improved to provide this functionality? Thanks.

    The mojo-executor will execute the mojo in an environment without any classpaths.
    You need to manually add the dependency.

    Dependency dep = new Dependency();  
dep.setGroupId("groupId");
dep.setArtifactId("artifactId");
dep.setVersion("0.0.1-SNAPSHOT");

Plugin assembly = MojoExecutor.plugin(
   "org.apache.maven.plugins", 
   "maven-assembly-plugin", 
   "2.3");

assembly.addDependency(dep)

MojoExecutor.executeMojo(assembly,
   MojoExecutor.goal("single"),
   ...
)
