随着1.0.0版本的的Andr​​oid对Maven的Eclipse 改变其管理的Maven的类路径的方式。非运行时依赖（实际上，任何事情不是在编译范围内）正在加载到一个新的Maven的，非运行时类路径容器。你看到这些库出现在这个新的类路径容器？

如果不行，请尝试从您的工作空间中删除项目，删除IDE特定的。* 元数据文件，并试图重新导入一个Maven项目。

I have an Android project in Eclipse managed by Maven. Yesterday I upgraded Eclipse and some plugins by the "Checked for Updated" function within Eclipse. After the update has finished, my Android project was defective. First I thought that it's just a "Clean/Update Project/Maven Rebuild" issue or maybe the order of the includes of the libraries didn't fit anymore (for example, Maven dependencies are not on top or something similar), but I was able to build by Maven, so no project or Maven problems, but an Eclipse problem. To get it working again I had to add Hamcrest, Junit and Mockito from the Maven repo to the build path manually. I didn't had to do that before in this project (except android-4.1.1.4.jar). I would like to understand when and why I suddenly have to do that? (In an earlier project I also had to add some external libraries manually).

(I always build and my project by clean install android:deploy android:run.)

Here are some important plugins I have currently installed...

This is the output of the error log

**The problem is that it doesn't find the classes (until I import it manually, but Maven and Eclipse should handle that) If I try to import for example org.junit.Test, org.junit.runner.RunWith or org.mockito.Mock I get in Eclipse

The import xxxxx cannot be resolved

Problems tab in Eclipse:

The project was not built since its build path is incomplete. Cannot find the class file for org.mockito.verification.VerificationMode. Fix the build path then try building this project com.mygame-TRUNK Unknown Java Problem The type org.mockito.verification.VerificationMode cannot be resolved. It is indirectly referenced from required .class files GameProcessorTest.java /com.mygame-TRUNK/src/test/java/com/mygam/game line 1 Java Problem

As of version 1.0.0 Android for Maven Eclipse has changed the way it manages the Maven classpaths. Non-runtime dependencies (effectively, anything not in the compile scope) are now loaded into a new Maven, non-runtime classpath container. Are you seeing these libraries appear in this new classpath container?

If not, please try deleting the project from your workspace, deleting the IDE-specific .* metadata files and trying re-importing as a Maven project.
