线程"main"中的异常java.lang.NoClassDefFoundError:junit/textui/ResultPrinter更新到Yosemite之后

我最近将我的系统从Mavericks(OSX)更新为Yosemite.我用来能够右​​键单击测试并运行它.现在我得到了例外

它也可能与我在我的Dock中点击打开的Android Studio图标时有关,我得到错误没有找到JVM,但我可以通过终端打开它没问题.

这与一个全新的android studio项目相同,默认的applicationTest试图运行.

所以有两件事

首先,如果你尝试在Yosemite升级上打开Android Studio并且它说"找不到JVM"你需要在这里安装java 6 for osx ,因为Android需要java 1.6而不是java 1.6+.

其次,我发现的异常是因为它试图运行JUnit,好像我想要运行java标准控制台而不是Android.

不要使用包含带箭头的黑色的Java测试,在Android测试中使用单元测试并删除JUnit配置的所有用法.

您的配置应该如下所示,然后您可以右键单击单个测试并像平常一样运行它们.

自Android Studio 1.1.0发布(2015年2月18日)以来,只要被测代码不调用Android API,就可以在本地JVM上的Android Studio中运行标准JUnit测试.请按照本指南中的说明获取更多信息.
