java - 具有可传递依赖项的 maven 程序集插件依赖项集

Question

我不明白如何将部分依赖添加到 <dependencySet>组装中

例如，我依赖于 group:artifact1 和 group:artifact2，它们都依赖于 group:artifact0。

我创建的程序集描述符应该复制 group:artifact2 和所有依赖项。

如果在 pom.xml 中对 group:artifact1 的依赖出现在对 group:artifact2 的依赖之前，我在目标目录中只有 group:artifact2，但是如果我改变依赖关系的顺序，那么我在目标目录中有两个 Artifact 。

结果我想有两个包含不同库集的目录。

简单的例子在这里

pom.xml

您需要创建多个 dependencySet s，每个要创建的目录一个，然后使用 includes或 excludes控制哪些依赖项进入哪个目录。

例如，如果您想要 spring-aop以 aop 结束目录和 spring-jdbc以 jdbc 结束目录，您将使用以下 dependencySet s:

<dependencySets>

  <dependencySet>
    <outputDirectory>aop</outputDirectory>
    <useProjectArtifact>false</useProjectArtifact>
    <includes>
      <include>org.springframework:spring-aop:jar</include>
    </includes>        
  </dependencySet>

  <dependencySet>
    <outputDirectory>jdbc</outputDirectory>
    <useProjectArtifact>false</useProjectArtifact>
    <includes>
      <include>org.springframework:spring-jdbc:jar</include>
    </includes>
  </dependencySet>

</dependencySets>

您需要确保引入正确的传递依赖项，可能是通过添加额外的 include s，但你明白了要点。
