我是Maven的新手,我想我已经开始了解它是如何工作的。但我无法理解maven程序集插件。我想要做到的是:
当所有的项目都打包好了,以及它们各自的依赖项时,我希望它们都在目标目录中。我不希望它们被打包成一个超级罐,因为系统是基于模块的。
让我解释一下,我在maven项目“公共”中有一个主要项目,服务器,还有两个模块,"core“和"android”。在公用文件夹中,也有我希望复制的conf文件夹。我想要这个结构:
我的项目结构是:
谢谢你的帮助,或指点正确的方式。:)
编辑这里是ant构建文件,可以工作100%,也许我应该坚持吗?

首先,组装插件所做的事情:它使生成一个tar或zip存档文件变得非常容易,其中包含了Maven项目的工件、依赖项和其他相关文件。
听起来,您所需要做的就是使用自定义描述符的设置程序集插件来输入您感兴趣的jars和配置文件。如果您有一个表示“可分发”功能的模块--即使该模块依赖于其他模块--那么您可能只需向其中添加一个装配描述符,其中包含一些文件、fileSets和/或dependencySets。
如果您的项目中有几个模块需要包含,并且不依赖于所有模块,那么您将需要查看moduleSets。我从来不用自己用过,但正是为了这个问题。

此设置将完全按照您的要求解决它。

此程序集描述符将将您的conf文件打包到一个单独的jar中,并且任何项目都将能够对其具有依赖关系。

dist模块将解压缩conf依赖项,并将其他依赖项复制到目标目录。

</project>我倾向于喜欢使用maven-dependency-plugin,我发现它非常强大。
dist模块将对其他模块具有所有必要的依赖关系,并按您的意愿下载和解压缩。如果您希望将其全部打包成zip或tar.gz或其他格式,那么您可以使用maven-assembly-plugin进行打包。

在为项目构建时,Maven将默认为以下结构:
然而,并不是所有的东西都丢失了!与maven中的大多数选项一样,这可以很容易地使用适当的配置标记覆盖。在您的示例中,您希望将标记下的outputDirectory标记(在每个模块POMS中)设置为正确的目录。
例如,应该编辑${basedir}/basedir/put.xml以添加以下行:
...
<build>
<outputDirectory>../target</outputDirectory>
...您的./android/pu.xml将进行类似的编辑:
...
<build>
<outputDirectory>../target/modules</outputDirectory>
...我不确定复制配置文件的最佳方法。您可能希望找到(或写,因为这是一个相当简单的操作)一个插件,只需复制文件,并给它一个范围,如“编译”,同时将它指向适当的目录。
