Question

hi有一种方法可以在Maven项目中获取pom文件的路径。我需要读取pom文件，并使用它来获取一些信息，例如版本，依赖项列表等。

 MavenXpp3Reader reader = new MavenXpp3Reader();
          Model model = reader.read(MainTest.class.getResourceAsStream( "how to get this path"+"/pom.xml"));
          for(Dependency d : model.getDependencies())
          {
              System.out.println(d.getArtifactId());
          }

Answer 1

一种解决方案是将有效pom复制到META-INF文件夹。检查此链接Add the effective pom.xml in the META-INF directory

Answer 2

您可以按照上述建议将pom添加到META-INF文件夹中。您还可以默认使用Jar和相关Maven存档插件将其放在META-INF中的pom.properties文件。无论哪种情况，只要罐子在类路径中，您就可以将其作为资源访问。我对此的唯一示例是用Groovy编写的：

def static String getMavenVersion(Class mainClass) {
    //
    // If this doesn't work, the likely reason is that we're running in development, so start with a
    // reasonable default
    //
    def String result = "Lastest Development"

    //
    // Get our package - one up in the tree is the path to the properties file we want.
    //
    def String packagePath = mainClass.package.name
    def int index = packagePath.lastIndexOf(".")
    def String groupId = packagePath.substring(0, index)
    def String artifact = packagePath.substring(index + 1)


    //
    // Get the version from the property file
    //
    Protect.resource
    {
        InputStream input = MiscUtils.class.getResourceAsStream("/META-INF/maven/${groupId}/${artifact}/pom.properties")
        input
    }
    { InputStream input ->
        if (input != null) {
            def Properties mavenProps = new Properties()
            mavenProps.load(input)
            result = mavenProps.getAt("version")
        }
    }

    result
}

example; 
 ı_____project files(pom.xml in this files) 
  I_____src 
   I____main 
    ı____java 
      ı___com 
       ı___file 
        ı___file2 
         ı___ my class

your be if class hierarchy;

 ....../pom.xml 
or
 ./../../../../../pom.xml

Answer 4

在maven项目中，项目目录具有pom.xml。
System.getProperty("user.dir")给出项目目录。
尝试- Model model = reader.read(MainTest.class.getResourceAsStream( System.getProperty("user.dir")+"/pom.xml"));
