I have a project (here called my-artifact) which needs to generate sources from a model file. I've created a maven-plugin (my-code-generator) which is used as described in the pom.xml excerpt below. It loads and processes the model.xml from my-artifact's resources and generates code using some predefined templates stored within the plugin. The question is how my-code-generator could access these templates as they are not in the project resources but within its own resources.
Thanks in advance

<artifactId>my-code-generator</artifactId>

Just use the ClassLoader, to get resources from the MyCodeGenerator Maven plugin.
Add something like this to your MyCodeGeneratorMojo
URL getTemplate(String fileName) {
return this.getClass().getResource(fileName);
}
Within the MyCodeGenerator Maven plugin, add the template(s) to the src/main/resources
directory (don't forget to use the correct package entry (directories) within that directory).

By including them in the jar file for the plugin and referencing them via classpath, via ClassLoader.getResourceAsStream.
By packaging them as another artifact, declaring them as a dependency, and calling the dependency-resolution API, which is a lot more work.
