如何使用gradle中的maven ant任务？

Question

我试图将一些工件发布到maven中央仓库并且由于当前版本的gradle(0.9-rc2)不处理pgp我以为我会尝试通过'移植'ant xml 版本同时等待gradle 1.0来尝试希望能够开箱即用.

我在gradle中写了以下内容:

def mvn = 
    groovy.xml.NamespaceBuilder.newInstance(ant, 'antlib:org.apache.maven.artifact.ant')

  mvn.mvn {
    arg(value: 'org.apache.maven.plugins:maven-gpg-plugin:1.1:sign-and-deploy-file')
    arg(value: '-Durl=file:///tmp/repo2')
    arg(value: '-DrepositoryId=sonatype-nexus-staging')
    arg(value: '-DpomFile=pom.xml')
    arg(value: '-Dfile=myjar.jar')
    arg(value: '-Dfile=-Pgpg')
  }

不幸的是它没有用,我得到了这个:

Cause: Problem: failed to create task or type antlib:org.apache.maven.artifact.ant:mvn
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any <presetdef>/<macrodef> declarations have taken place.
No types or tasks have been defined in this namespace yet

我尝试了各种组合,包括在我的脚本顶部添加以下内容:

buildscript {
  repositories {
    mavenCentral()
  }
  dependencies {
    classpath 'org.apache.maven:maven-ant-tasks:2.1.1'
  }
}

任何帮助将非常感激

谢谢严

我没有找到使用NamespaceBuilder的方法,但我找到了另一种方法可以直接使用该任务来解决我的问题:

repositories {
  mavenCentral()
}

configurations {
    mavenAntTasks
}

dependencies {
    mavenAntTasks 'org.apache.maven:maven-ant-tasks:2.1.1'
}

task hello << {
  ant.taskdef(resource: 'org/apache/maven/artifact/ant/antlib.xml',
              uri: 'antlib:org.apache.maven.artifact.ant',
              classpath: configurations.mavenAntTasks.asPath)
  ant.mvn(...)
}
