仅从pom文件中检索依赖项

标签： java maven

我正在做一些静态挖掘，我希望有一个相关库的列表。

有没有办法以编程方式查找pom.xml文件使用的依赖项？

我不能使用.m2 repo或类似的东西，因为代码没有编译。

（换句话说，我想重新创建＆＃34; Efective POM＆＃34; pom.xml文件的标签，如Eclipse中所示）

请注意，读取当前项目的pom文件（测试boottstrap）会在要求时提供一组依赖项，但不会使用外部pom文件。 在代码中：

[...]
Model model = mavenReader.read(new FileReader(pomFile));
model.setPomFile(pomFile);

proj= new MavenProject(model);
proj.setRemoteArtifactRepositories(
Arrays.asList((ArtifactRepository) new MavenArtifactRepository(
        "maven-central",
        "http://repo1.maven.org/maven2/", 
        new DefaultRepositoryLayout(), 
        new ArtifactRepositoryPolicy(),
        new ArtifactRepositoryPolicy())));

List<Dependency> dependencies = proj.getDependencies();
for (Dependency dependency : dependencies) {
    System.out.println(dependency);
}

使用pomFile = new File("pom.xml")，它大叫：

Dependency {groupId=com.github.javaparser, artifactId=javaparser-core, version=3.5.4, type=jar}
Dependency {groupId=com.jcabi, artifactId=jcabi-aether, version=0.7.19, type=jar}
Dependency {groupId=org.apache.maven, artifactId=maven-core, version=3.0.3, type=jar}
Dependency {groupId=org.apache.maven.plugins, artifactId=maven-dependency-plugin, version=3.0.2, type=jar}
Dependency {groupId=org.apache.maven.plugin-tools, artifactId=maven-plugin-annotations, version=3.5, type=jar}

使用XX建议，Runtime.getRuntime().exec("cmd /c mvn dependency:tree");

输出是（在其他人之间）：

完全正是我想要的。但问题是，我不想知道我的项目的依赖树是什么样的。我想调查其他项目。

现在，使用pomFile = new File("[externalPath].pom.xml")，它找不到任何依赖项。 （该文件存在且包含正确的pom isntructions）。

答案 0 :(得分：1)

您可以启动一个运行mvn help:effective-pom的单独进程。此命令返回带有“有效pom”的xml。稍后您可以解析该XML以获取依赖关系。

如果您对传递依赖感兴趣，可以以类似的方式使用mvn dependency:tree。
