我是新手,我开始使用安装Gradle指南.

当我按照指南的’环境变量’步骤,我将GRADLE_HOME设置为/ path / to / gradle并将/ path / to / gradle / bin添加到〜/ .bashrc中的PATH.

我在命令行中运行gradle -v,它给了我这个错误：

Exception in thread "main" java.lang.NoClassDefFoundError: org/gradle/launcher/GradleMain
Caused by: java.lang.ClassNotFoundException: org.gradle.launcher.GradleMain
    at java.net.URLClassLoader$1.run(URLClassLoader.java:202)

    at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
Could not find the main class: org.gradle.launcher.GradleMain.  Program will exit.

它看起来像类路径丢失所以我将CLASSPATH变量设置为’.：path / to / gradle / lib / gradle-launcher-1.2.jar’并再次登录.它还没有工作……

任何提示

Thx in Advance
