Maven Eclipse-Aether: getLicence() method

I'm developing a maven-plugin to check dependencies' licenses, similar to this one, but I can't found any API for that... what I would like to have is something like 

String licence = artifact.getLicence();

mrice on that license-check plugin just try to find the .pom file of that artifact, read it, and try to find the <license></license>.

Do you know how can I do this?

Solution

  • You need to use org.apache.maven.model.License. (See api docs for details).

    Something like this:

    try {
    Reader reader = new FileReader(pomXmlFile);
    Model model;
    try {
        final MavenXpp3Reader xpp3Reader = new MavenXpp3Reader();
        model = xpp3Reader.read(reader);
    } finally {
        reader.close();
    }
    List<License> licenses = model.getLicenses();
} catch (XmlPullParserException ex) {
    ex.printStackTrace();
} catch (IOException ex) {
    ex.printStackTrace();
}

    *Note that many poms do not have a license.
