Exception in thread "main" java.lang.NoClassDefFoundError: junit/textui/ResultPrinter After updating to Yosemite

Question

我最近将我的系统从 Mavericks (OSX) 更新到 Yosemite。我曾经能够右键单击测试并运行它。现在我得到异常

它也可能与当我在我的 Dock 中点击打开 Android Studio 图标时出现错误，没有找到 JVM 但我可以通过终端打开它没问题。

这与默认 applicationTest 尝试运行的全新 android 工作室项目相同。

Answer 1

所以两件事

首先，如果您尝试在 Yosemite 升级时打开 Android Studio，它显示 "No JVM found" 您需要为 osx 安装 java 6 here 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 就好像我想运行通过 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，使用 Android 测试中的单元测试并删除 JUnit 配置的所有使用。

您的配置应如下所示，然后您可以右键单击单个测试并运行它们像往常一样。

Answer 2

自 Android Studio 1.1.0 发布（2015 年 2 月 18 日）起，现在可以在本地 JVM 上的 Android Studio 中运行标准 JUnit 测试只要被测代码不调用 Android API。请按照 this guide 中的说明获取更多信息。
