maven java读取maven的pom.xml文件详解编程语言

可以使用maven官方的 maven-model里的MavenXpp3Reader类来读取pom.xml文件， 需要引用maven jar包：

<dependency> 
            <groupId>org.apache.maven</groupId> 
            <artifactId>maven-model</artifactId> 
            <version>3.0</version> 
        </dependency>

当然，也可以直接找到pom的安装路径下的lib目录找到maven-model-3.1.0.jar文件，引用到项目中。

import org.apache.maven.model.Model; 
import org.apache.maven.model.io.xpp3.MavenXpp3Reader; 
import org.codehaus.plexus.util.xml.pull.XmlPullParserException; 
 
import java.io.File; 
import java.io.FileNotFoundException; 
import java.io.FileReader; 
import java.io.IOException; 
 
/**

 */ 
public class Main { 
    public static void main(String[] args) throws IOException, XmlPullParserException { 
        MavenXpp3Reader reader = new MavenXpp3Reader(); 
        String myPom = System.getProperty("user.dir") + File.separator + "pom.xml"; 
        Model model = reader.read(new FileReader(myPom)); 
    } 
}

如果你需要解析pom的父pom，以及父依赖等信息，需要用到ModelBuildingRequest 类，实例代码如下。

ModelBuildingRequest req = new DefaultModelBuildingRequest(); 
req.setProcessPlugins( false ); 
req.setPomFile( file ); 
req.setModelResolver( new RepositoryModelResolver( basedir, pathTranslator ) ); 
req.setValidationLevel( ModelBuildingRequest.VALIDATION_LEVEL_MINIMAL ); 
 
Model model; 
try 
{ 
    model = builder.build( req ).getEffectiveModel(); 
} 
catch ( ModelBuildingException e ) 
{ 
     ... 
}
