jUnit测试在Eclipse中有效，但在java.lang.RuntimeException:Stub中失败

Question

我的项目有单元测试。它们在Eclipse中运行良好，但在ant中失败并出现错误：

java.lang.RuntimeException: Stub!

根据本文，我已经从EclipseIDE自动生成了我的ant build.xml。

我的build.xml文件：

    <?xml version="1.0" encoding="UTF-8" standalone="no"?>

ant版本：1.9.2

junit版本：4.8.2

Android开发工具版本：v210.0-531062

UPD:我有以下错误：

java.lang.RuntimeException: Stub!

UPD2:运行时类路径和构建类路径相同。

Answer 1

当android.jar在类路径中的junit.jar之前被引用时，就会出现问题。

在您的build.xml中，顺序似乎是正确的，但您指定了带有空格的id：

<path id="JUnit 4.libraryclasspath">

您应该使用不带空格或其他特殊字符的id（不过.-_也可以）。

UPD1中的stacktrace没有显示junit，这是缺少lib的另一个指示。
