jUnit tests work in Eclipse, but fail in ant - java.lang.RuntimeException: Stub

Question

I have unit tests for my project. They run fine in Eclipse but fail in ant with errors:

java.lang.RuntimeException: Stub!

I've automaticaly generated my ant build.xml from EclipseIDE acording to this article.

My build.xml file:

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

Answer 1

The problem occurs when the android.jar is referenced before the junit.jar in the classpath.

In your build.xml, the order seems correct, but you specified the id with a space in it:

<path id="JUnit 4.libraryclasspath">

You should use ids without spaces or other special characters (.-_ are ok, though).

The stacktrace in your UPD1 shows no junit, which is another indication for a missing lib.
