mvn javadoc:javadoc仅在我的Module项目之一上失败 [英] mvn javadoc:javadoc failing on just ONE of my Module project

问题描述

我的Sub modules项目确实有一个非常奇怪的问题.

I have really very strange problem with my Sub modules project.

项目结构如下.

TestPomProject

TestPomProject

* DAOProject
* SchemaProject
* EJBProject
* EarProject

如果我在这些项目(DAOProject，SchemaProject，EarProject)上执行"mvn javadoc:javadoc"命令，则工作正常且成功完成.

If i execute "mvn javadoc:javadoc" command on these projects ( DAOProject, SchemaProject, EarProject ) It's working fine and completed successfully.

但是，当我在EJBProject上执行此命令时，它给了我以下异常，并且EJBProject中的javadoc没有任何不同的条目，而javadoc插件都具有相同的条目........

But when i execute this command at EJBProject it's giving me following exception and there isn't any different entry for javadoc in EJBProject all having same entry for javadoc plugin ........

有趣的是，mvn install命令对IMPORT语句没有任何抱怨，它可以成功构建它！!!!

And the interesting thing is mvn install command doesn't complain me anything about IMPORT statements and it build it successfully !!!!

请给我一些想法，这是怎么了?发生了什么事?

Please give me some idea what's wrong here ?? What's going on ?
