我的目标是包括一场战争到另一场战争。请参阅我的项目结构:

+test-parent ( spring和hibernate框架的所有公共依赖项) -- test-core (所有公共类类型的集合:jar) -- test-web (应该作为单独的webapp运行的webapp,取决于test-core,type:war) - test-web-2 (取决于test-web,test-core,type:war)

我已经使用maven war插件来实现这一点。

由于我的测试-web-2依赖于测试-web,我想合并所有的类,资源测试-web-2.当我运行mvn install时,我的所有构建都是成功的,但是当我在服务器上运行test或test 2时,它在WEB下没有lib文件夹,并且有来自父服务器的所有必需的spring jars。

我在两个项目中都给出了不同的包和jsp文件名。我甚至能够看到适当的合并构建的要求。

如何在test-web和test-web-2项目中生成这个lib文件夹,并从父项目中获得所有依赖的jars?

简化项目配置。将java源代码从WAR分离到JAR。在此之后,您可以简单地将这个JAR作为依赖项添加到另一个WAR中。在这种情况下合并java代码不是个好主意。

要从WAR合并资源,请使用maven 覆盖层

我认为问题在于,您正在尝试做一些不符合J2EE标准的事情。在另一个war文件中包含一个war文件是没有意义的。

处理此类依赖关系的“标准”方法是将部署打包为.ear文件,共享资源打包为ear中的jar文件,war文件也在ear文件中使用这些共享依赖项。

看看maven打包插件的“耳朵”打包选项。
