repositories {
    ....
    maven {
        name = "GitHubPackages"
        url = uri("https://maven.pkg.github.com/a-fujimt/gen.mjava")
        credentials {
            username = project.hasProperty("GITHUB_USER") ? GITHUB_USER : ''
            password = project.hasProperty("GITHUB_TOKEN") ? GITHUB_TOKEN : ''
        }
    }
}
dependencies {
  implementation 'com.fujimotoakira:gen.mjava:1.0-SNAPSHOT'
  implementation 'com.github.gumtreediff:core:version' // GumTree
  implementation 'com.github.gumtreediff:client:version' // GumTree

Parsing a file

Using the generator registry (ref)

Run.initGenerators(); // registers the available parsers
String file = "myfile.mjava";
TreeContext tc = TreeGenerators.getInstance().getTree(file); // retrieves and applies the default parser for the file 
Tree t = tc.getRoot(); // retrieves the root of the tree
System.out.println(t.toTreeString()); // displays the tree in our ad-hoc format

Using mjava JDT generator (ref)

String file = "myfile.mjava";
Tree tree = new MJdtTreeGenerator().generateFrom().file(file).getRoot(); // instantiates and applies the MJDT generator
