Get MavenProject from just the POM.xml - pom parser?

Question

Is it possible to get an instance of org.apache.maven.project.MavenProject or some other object form of the POM from just the pom.xml file?

Thanks in advance.

yes you can . This is the code. You need maven-model-3.0.4.jar and plexus-utils-2.0.6.jar and maven-core-3.0.4.jar

Model model = null;
FileReader reader = null;
MavenXpp3Reader mavenreader = new MavenXpp3Reader();
try {
    reader = new FileReader(pomfile);
    model = mavenreader.read(reader);
    model.setPomFile(pomfile);
}catch(Exception ex){}
MavenProject project = new MavenProject(model);

Tried you solution but it doesn't populate some fields of the MavenProject object that I was expecting, like getCompileSourceRoots() returns empty list. – javydreamercsw Nov 21 '12 at 20:43

Reading a pom file does not involve interpolation of data such as variables, inherited settings from parents (and their proto-parents) and so on. – carlspring Jul 11 '13 at 14:26

If you want to get the MavenProject based on groupid, artifactId and version you have to run inside of a maven plugin. And this code will do the job:

ProjectBuildingRequest configuration = new DefaultProjectBuildingRequest();
configuration.setProcessPlugins( false );
configuration.setRepositorySession( session );
org.apache.maven.artifact.Artifact artifact = new org.apache.maven.artifact.DefaultArtifact(groupId, artifactId, version, "compile", "", "", new DefaultArtifactHandler());
MavenProject project = projectBuilder.build(artifact, configuration).getProject();

The missing properties can be injected into the maven plugin.
