目前我的NetBeans 8.0一直在做最奇怪的事情。
我有一个多模块项目。如果模块在maven存储库中,通常我甚至不必打开或甚至下载项目。目前,我的一些模块需要打开和构建,因此“target”文件夹位于项目目录中,并填充了类。如果不是,我得到一个NoClassDefFoundError。
错误如下所示:
Exception in thread "main" java.lang.NoClassDefFoundError: SOME/CLASS/THAT/IS/EXPECTED/IN/TARGET/FOLDER/OF/SOME/MODULE/THAT/IS/A/DEPENDENCY
at ...
Caused by: java.lang.ClassNotFoundException: com.example.SOME.CLASS.THAT.IS.EXPECTED.IN.TARGET.FOLDER.OF.SOME.MODULE.THAT.IS.A.DEPENDENCY

我的POM看起来像这样:

为什么它突然需要一个带有类的目标文件夹?它不应该从依赖项中获取它们吗?从存储库?
