通过groovy xmlSurper读取POM xml文件的特定内容并下载依赖项

Question

我有一个下面的POM文件。我想使用xmlSlurper groovy代码来读取POM文件的特定内容，谁能告诉我如何编写代码来通过groovy xmlSlurper读取特定内容。我想读取下面POM文件中作用域为运行时的那些的groupid工件id、分类器和类型。

下面是我用来读取POM文件内容并从ArtiFactory下载其作用域为运行时的依赖项的脚本。

apply plugin: 'java'

// ------ Tell the script to get dependencies from artifactory ------
    repositories {
         maven {
        url "http://abc.de.fg:80/artifactory/fes-release-local"
              }
        }

    buildscript {
    repositories {
      maven {
        url "http://abc.de.fg:80/artifactory/libs-snapshot"
         }
    }
    // ------ Tell the script to get dependencies from artifactory ------
    dependencies {
    classpath ([ "cop.trn.cm:cmugin:1.2.147" ])
  }
}

apply plugin: 'com.uven.eplugin'

/**

println "Deploying ${System.properties.jobName}.${System.properties.buildNumber} to ${System.properties.deployLayer}"

// load the deploy properties from the file
