我一直在尝试解析 maven pom.xml。我在一定程度上是成功的。但我的问题是我无法获得默认值。我必须手动注入默认值。例如,如果 pom.xml 中没有指定版本号,那么很明显会使用父版本。如果没有指定构建目录,那么它将是目标。

我需要知道,我应该使用哪些类来自动填充这些东西。除此之外,我想为我构建依赖关系图。我用来解析的代码是

        Model model = null;
    FileReader reader = null;
    MavenXpp3Reader mavenreader = new MavenXpp3Reader();
    try {
        reader = new FileReader(pomfile);
        model = mavenreader.read(reader);
        model.setPomFile(pomfile);

        if (model.getBuild() != null) {
            // location of output directory basically target
            if (model.getBuild().getDirectory() == null) {
            //set the build directory

            } // location of compiled classes
            if (model.getBuild().getOutputDirectory() == null) {
                      // set the classes directory
            }
        }
    } catch (FileNotFoundException e) {
        e.printStackTrace();
        throw new RuntimeException("pom file not found " + pomfile);
    } catch (IOException e) {
        e.printStackTrace();
        throw new RuntimeException("pom file is not accessible " + pomfile);
    } catch (XmlPullParserException e) {
        e.printStackTrace();
        throw new RuntimeException("unable to parse pom " + pomfile);
    } catch (NullPointerException nullPointerException)
        System.out.println("Exception setting build dir "+model.getPackaging());

    } finally {
        if (reader != null) {
            reader.close();
        }
    }

谢谢。

Look at the code for the help:effective-pom plugin goal, or actually use it to dump the effective POM and xml-parse the result.
