无法启动Groovy控制台

Question

我刚刚通过GVM工具在OSX10.10.3中重新安装了Groovy2.4.3。我还使用GVM安装了相关库和工具，如groovyserv、grails和gradle。我使用的Java版本是1.8.0_25。

除了不能通过命令groovyConsole启动Groovy控制台这一例外，一切似乎都很好，因为我一直在获取这个异常：

解决这个问题的最好方法是什么？

Answer 1

我以前有过这个，这是由于环境类路径变量被设置为指向无效的jar。

Answer 2

我也有同样的问题。在我的例子中，JAVA_HOME路径是错误的。因此，我设置了JAVA_HOME，然后它的工作没有任何问题。

在设置JAVA_HOME之后，它启动了：
