JUnit：NoClassDefFoundError：org / junit / runner / manipulation / Filter [英] JUnit: NoClassDefFoundError: org/junit/runner/manipulation/Filter

问题描述

当我尝试运行某些单元测试时，会引发以下错误：

When I try to run some unit tests, the following error is raised:

java.lang.NoClassDefFoundError: org/junit/runner/manipulation/Filter
    at java.lang.Class.forName0(Native Method)
    at java.lang.Class.forName(Class.java:190)
    at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.loadTestLoaderClass(RemoteTestRunner.java:320)
    at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.createRawTestLoader(RemoteTestRunner.java:310)
    at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.createLoader(RemoteTestRunner.java:305)
    at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.defaultInit(RemoteTestRunner.java:283)
    at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.init(RemoteTestRunner.java:207)
    at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:191)

我必须提到junit-4.11.jar已添加到项目中建立路径。任何想法？

I have to mention that junit-4.11.jar is added to project build path. Any ideas?

2. 单击Libraries选项卡。


3. 单击添加库按钮。


4. 选择JUnit并单击下一步。


5. 选择JUnit 4（这就是我正在使用的）。


6. 点击完成。


7. 现在右键单击包含单元测试的文件，然后选择属性。


8. 在Run /下调试设置，从该文件的启动配置中删除任何条目。点击确定。

1. Right click the project in Package Explorer, and click Properties.
2. Click the Libraries tab.
3. Click the Add library button.
4. Select JUnit and click Next.
5. Select JUnit 4 (that's what I am using).
6. Click finish.

8. Under the Run/Debug settings, remove any entries from the Launch Configurations for that file. Hit ok.

希望你现在可以运行测试。

Hopefully you'll be able to run the tests now.
