Question

我正在尝试使用以太来获取maven工件的依赖关系。我看到一个RepositorySystem.collectDependencies（），但它只获取编译和运行时范围的依赖项。如何获取工件的所有依赖项，包括test和provided？

Answer 1

看看jcabi-aether（我是开发人员），它是Sonatype Aether的包装器：

File repo = this.session.getLocalRepository().getBasedir();
Collection<Artifact> deps = new Aether(this.getProject(), repo).resolve(
  new DefaultArtifact("junit", "junit-dep", "", "jar", "4.10"),
  JavaScopes.RUNTIME
);

Answer 2

假设您使用DefaultRepositorySystemSession，您可以执行以下操作：

defaultRepositorySystemSession.setDependencySelector(new DependencySelector() {
    @Override
    public boolean selectDependency(Dependency dependency) {
        return true;
    }

    @Override
    public DependencySelector deriveChildSelector(DependencyCollectionContext context) {
        return this;
    }
});

然后

CollectResult result = repositorySystem.collectDependencies(defaultRepositorySystemSession, request);

Here is an example project that does this.

这三个文件：

https://github.com/terraframe/Runway-SDK/tree/v1.8.0/runwaysdk-server/src/main/java/com/runwaysdk/business/generation/maven

使用Aether是一个独立的工作示例。

它工作了几个月然后我突然出现了一个问题，有时在Mac JRE上会在com.sun：tools.jar上抛出DependencyResolutionException。

祝你好运，如果你决定使用它，我会转而使用maven-dependency-plugin dependency:build-classpath。

Answer 4

您可以在Eclipses Aether中使用DependencyFilter。下面的示例complete version可以在这个令人敬畏的Aether snippets.

集中找到

DependencyFilter classpathFilter = DependencyFilterUtils.classpathFilter(JavaScopes.COMPILE, JavaScopes.PROVIDED);

CollectRequest collectRequest = new CollectRequest();
collectRequest.setRoot( new Dependency( artifact, JavaScopes.COMPILE ) );
collectRequest.setRepositories(repositories);

DependencyRequest dependencyRequest = new DependencyRequest( collectRequest, classpathFilter );

List<ArtifactResult> artifactResults =
    system.resolveDependencies( session, dependencyRequest ).getArtifactResults();

<强>更新

版本0.9.0M3与Maven 3.1.0不兼容，所以不要在Maven中使用它，即在插件中使用它。

Answer 5

Take a look at this github project: https://github.com/Gemba/mvn-dd
It downloads all dependencies including test and provided.
It uses aether's library to fetch them.

如何使用以太获取所有maven依赖项？
