Question

I m facing a problem with maven build. I have several ejb projects. After maven build the jar-file contains the maven descriptor in META-INF/maven twice, i.e. if I extract files to disk 7zip asks to overwrite files although extracted to a new folder. If a specify <addMavenDescriptor>false</addMavenDescriptor> in the archive-tag of the ejb plugin then the maven decriptor is still generated but only once. Is there another place where I can disable maven descriptor generation or does anybody know the reason for the duplicate generation?

项目结构类似:

-pom
  -ejb

The pom.xml of the EJB model:

这里是母体项目的om。

我发现,这是一个特别的问题,可以 version出文字(我有8项审判)和小2英原始版本的档案。以上行为(重复生成ma字器)只有在我的工作空间增加EJB项目的情况下才会发生。这意味着,如果我把EJB项目从工作空间(不删除磁盘上的内容)移走,那么,工作空间(包括EJB项目,而EJB项目则不为人所知)中只存在一个等级的母母母子项目,那么所有项目都会奏效。奇怪,吗?

BTW:在目前的ec(java ee Pack)上,这只 does子就会出现,所有罚款都是在那里。
