不知道这是什么错，最开始因为无法下载gradle-2.4-all.zip库，导致编译无法通过，后来手动在网上下载了一个gradle-2.4-all.zip库放到本地运行，结果现在报以下错误，求大神解答
Exception in thread “main” java.lang.NullPointerException
at org.gradle.wrapper.PathAssembler.getDistName(PathAssembler.java:77)
at org.gradle.wrapper.PathAssembler.getDistribution(PathAssembler.java:43)
at org.gradle.wrapper.Install.createDist(Install.java:43)
at org.gradle.wrapper.WrapperExecutor.execute(WrapperExecutor.java:129)
at org.gradle.wrapper.GradleWrapperMain.main(GradleWrapperMain.java:48)
执行命令出错，返回值：1。
下面是我改动之后的gradle-wrapper.properties文件内容：
#Wed Apr 10 15:27:10 PDT 2013

distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
