在与Grails 2合作完成非常完美的体验之后，碰到这个问题，

这是怎么发生的，它是一个完整的头脑风暴我：

  java.lang.NoClassDefFoundError：Lgrails / test / mixin / services / ServiceUnitTestMixin; 
  

...任何反馈都将最受欢迎。

我遇到了类似的问题，并按照以下顺序解决了这个问题：

1. 删除目标目录中的所有内容
   
2. grails clean


3. grails编译


4. grails run-war

Got a Grails 2 app and executing run-app works fine, run-war fails:

Just run into this problem after having a pretty much flawless experience of working with Grails 2,

How has this come about is a complete headscratcher for me:

java.lang.NoClassDefFoundError: Lgrails/test/mixin/services/ServiceUnitTestMixin;

... any feedback will be most appreciated.

解决方案

I encountered a similar issue and solved it by doing the following in order:

1. Delete everything in the target directory
2. grails clean
3. grails compile
4. grails run-war
