示例1: execute
import org.apache.maven.shared.dependency.tree.traversal.DependencyNodeVisitor; //导入依赖的package包/类
@Override
public void execute() throws MojoExecutionException, MojoFailureException {
try {
// find the nar dependency
Artifact narArtifact = null;
for (final Artifact artifact : project.getDependencyArtifacts()) {
if (NAR.equals(artifact.getType())) {
// ensure the project doesn't have two nar dependencies
if (narArtifact != null) {
throw new MojoExecutionException("Project can only have one NAR dependency.");
}
// record the nar dependency
narArtifact = artifact;
}
}
// ensure there is a nar dependency
if (narArtifact == null) {
throw new MojoExecutionException("Project does not have any NAR dependencies.");
}
// build the project for the nar artifact
final ProjectBuildingRequest narRequest = new DefaultProjectBuildingRequest();
narRequest.setRepositorySession(repoSession);
narRequest.setSystemProperties(System.getProperties());
final ProjectBuildingResult narResult = projectBuilder.build(narArtifact, narRequest);
// get the artifact handler for excluding dependencies
final ArtifactHandler narHandler = excludesDependencies(narArtifact);
narArtifact.setArtifactHandler(narHandler);
// nar artifacts by nature includes dependencies, however this prevents the
// transitive dependencies from printing using tools like dependency:tree.
// here we are overriding the artifact handler for all nars so the
// dependencies can be listed. this is important because nar dependencies
// will be used as the parent classloader for this nar and seeing what
// dependencies are provided is critical.
final Map<String, ArtifactHandler> narHandlerMap = new HashMap<>();
narHandlerMap.put(NAR, narHandler);
artifactHandlerManager.addHandlers(narHandlerMap);
// get the dependency tree
final DependencyNode root = dependencyTreeBuilder.buildDependencyTree(narResult.getProject(), localRepository, null);
// write the appropriate output
DependencyNodeVisitor visitor = null;
if ("tree".equals(mode)) {
visitor = new TreeWriter();
} else if ("pom".equals(mode)) {
visitor = new PomWriter();
}
// ensure the mode was specified correctly
if (visitor == null) {
throw new MojoExecutionException("The specified mode is invalid. Supported options are 'tree' and 'pom'.");
}
// visit and print the results
root.accept(visitor);
getLog().info("--- Provided NAR Dependencies ---\n\n" + visitor.toString());
} catch (DependencyTreeBuilderException | ProjectBuildingException e) {
throw new MojoExecutionException("Cannot build project dependency tree", e);
}
}
