Java Eclipse使用旧的PATH变量在Gradle任务中执行命令行进程？

我使用Gradle任务。它执行一个命令行进程。我要执行的命令是：

pod install 

它需要安装。我做到了。我使用

pod--version

从命令行检查它是否工作。输出为最新版本，即0.37.2。我的系统是OSX，我使用最新的EclipseLuna版本

我创建了一个自定义Gradle任务：

class InstallPodTask extends DefaultTask {

      @InputDirectory File srcDir

      @TaskAction
      def pod() {

        def xcodeProjectDir = // the dir the pod command is executed in

        try {
           project.exec {
              workingDir xcodeProjectDir
              executable "pod"
              args "install"
           }   
        } catch (Exception exception) { 

        }

     }
}

当我从命令行使用此任务时，它可以正常工作

当任务在Eclipse中执行时，就会出现问题。我使用eclipse的gradle插件。从eclipse运行上述任务时，我遇到以下错误：
