eclipse 运行juni 测试 ClassNotFoundException

down vote

在eclipse 运行 基于maven的Junit test: Class not found com.myproject.server.MyTestjava.lang.ClassNotFoundException: com.myproject.server.MyTest at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:423) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:356) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.loadClass(RemoteTestRunner.java:693) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.loadClasses(RemoteTestRunner.java:429) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:452) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) I've tried adding JUNIT library in the classpath although I'm using maven, and the Junit library is in the POM dependency. I already have tried cleaning the project and created a new Junit test case using the Junit plugin for Eclipse, still getting the same error.

 

解决方法： 改为命令mvn clean compile test-compile

下面是原因：

I realize this is a bit belated of a response, but I was running into the same issue and thought I would contribute the solution I found.

This appears to occur because only the source code is compiling when you use "mvn clean compile" (I'm using maven 3.1.0 so I'm not sure if it always behaved like this). If you run "mvn test", the test code will compile as well, but then it runs the tests (which may not be immediately desirable if you're trying to run them through Eclipse. The way around this is to add test-compile to your mvn command sequence whenever you do a "mvn clean". For example, you would run "mvn clean compile test-compile".
