Maven组件插件-包括子模块的依赖项?

问题描述

我正在尝试为大型多模块项目设置程序集插件.现在的目标是将我所有的工件放入一个目录中.这是我的描述符:

    <assembly
xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0 http://maven.apache.org/xsd/assembly-1.1.0.xsd">
<id>Install-Package</id>
<formats>
    <format>dir</format>
</formats>
<includeBaseDirectory>false</includeBaseDirectory>
<dependencySets>
    <dependencySet>
        <unpack>false</unpack>
        <scope>runtime</scope>
        <outputDirectory>dependencies</outputDirectory>
    </dependencySet>
</dependencySets>
<moduleSets>
    <moduleSet>
        <binaries>
            <unpack>false</unpack>
        </binaries>
    </moduleSet>
</moduleSets>

当前，这会将我所有的工件复制到Assembly目录.到目前为止，一切都很好.问题在于，依赖项文件夹仅包含主pom文件中列出的依赖项.有没有一种方法可以在程序集中包含子模块的依赖项，而不必在根pom中列出所有子模块? (将它们全部包含在root pom上会给子模块增加额外的未使用依赖性，如果它们是单独构建的.)

谢谢！

解决方案

是的，这就是顶部" dependencySets的作用.

删除顶部" dependencySets，并在moduleSet的binaries元素下声明一个:

<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0 http://maven.apache.org/xsd/assembly-1.1.0.xsd">
  <id>Install-Package</id>
  <formats>
    <format>dir</format>
  </formats>
  <includeBaseDirectory>false</includeBaseDirectory>
  <moduleSets>
    <moduleSet>
      <binaries>
        <unpack>false</unpack>
        <dependencySets>
          <dependencySet>
            <unpack>false</unpack>
            <scope>runtime</scope>
            <outputDirectory>dependencies</outputDirectory>
          </dependencySet>
        </dependencySets>
      </binaries>
    </moduleSet>
  </moduleSets>
</assembly>

I am trying to setup the assembly plugin for a large multi-module project. The goal right now is to just get all of my artifacts into a directory. Here is my descriptor:

    <assembly
xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0 http://maven.apache.org/xsd/assembly-1.1.0.xsd">
<id>Install-Package</id>
<formats>
    <format>dir</format>
</formats>
<includeBaseDirectory>false</includeBaseDirectory>
<dependencySets>
    <dependencySet>
        <unpack>false</unpack>
        <scope>runtime</scope>
        <outputDirectory>dependencies</outputDirectory>
    </dependencySet>
</dependencySets>
<moduleSets>
    <moduleSet>
        <binaries>
            <unpack>false</unpack>
        </binaries>
    </moduleSet>
</moduleSets>

Currently, this copies all of my artifacts to the assembly directory. So far, so good. The problem is that the dependencies folder only includes dependencies that are listed in the main pom file. Is there a way to include the dependencies of the sub modules in the assembly without listing them all in the root pom? (Including them all on the root pom would add extra unused dependencies to the sub modules if they are built separately).

Thanks!

Yes, this is what a "top" dependencySets does.

Remove the "top" dependencySets and declare one under the binaries element of your moduleSet:

<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0 http://maven.apache.org/xsd/assembly-1.1.0.xsd">
  <id>Install-Package</id>
  <formats>
    <format>dir</format>
  </formats>
  <includeBaseDirectory>false</includeBaseDirectory>
  <moduleSets>
    <moduleSet>
      <binaries>
        <unpack>false</unpack>
        <dependencySets>
          <dependencySet>
            <unpack>false</unpack>
            <scope>runtime</scope>
            <outputDirectory>dependencies</outputDirectory>
          </dependencySet>
        </dependencySets>
      </binaries>
    </moduleSet>
  </moduleSets>
</assembly>
