将'emma'添加到Android ant build会触发"局部变量类型不匹配"异常

Question

我试图在测试Android项目时运行Emma,该项目是Java和C/JNI代码的组合.构建和测试工作正常,但每当我添加emma,我得到一个神秘的例外.我正在使用Android SDK v20.1和NDK r8b.

该项目在这里,它是一个Android库项目:https: //github.com/guardianproject/IOCipher ,测试在这里:https: //github.com/guardianproject/IOCipherTests

该build.xml文件是使用生成的android update test-project.ant clean debug install test每次运行都会ant clean emma debug install test触发异常:

这是例外:

我遇到了同样的错误。在我的项目中，我们在一个项目中有一个单元测试应用程序，它包装了另一个包含单元测试本身的项目。这两个项目都引用了我的 SDK，正如 chaitanya 所建议的，这导致 emma 两次检测 SDK 代码。通过删除单元测试项目中对 SDK 的引用，我能够解决该错误。
