使用资源插件从相邻的Maven模块复制静态文件和目录？

Question

我有一个与当前模块相邻的模块，并希望从相邻模块中获取一个包含其子级的目录，并将其内容复制到目标目录中。

我想知道在目录指令中获取到相邻家伙的相对路径的最佳方法。

您不必显式声明maven-resources-plugin的执行。也可以在default-resources执行中简化POM来实现：

  <build>
    ...
    <resources>

      <resource>
        <targetPath>..</targetPath>  <!--  relative to the target/classes directory
                                           (i.e. ${project.build.outputDirectory}) -->
        <directory>src/main/resources</directory>
        <filtering>true</filtering>
      </resource>

      <resource>
        <targetPath>..</targetPath>
        <directory>../adjacent/src/main/docker/</directory>
        <filtering>true</filtering>
        <includes>
          <include>**/*</include>
        </includes>
        <excludes>
          <exclude>**/nodes/**</exclude>
          <exclude>**/data/**</exclude>
        </excludes>
      </resource>

      <resource>
        <targetPath>..</targetPath>
        <directory>../adjacent/src/main/docker/</directory>
        <filtering>false</filtering>
        <includes>
          <include>**/data/**</include>
        </includes>
      </resource>

    </resources>
  ...
</build>

对于<directory>“ The path is relative to the POM.”。因此，../adjacent/src/...可以。

这还有一个优势，即Eclipse m2e插件会考虑这些声明，即，资源是在 Project → Clean ... 而不是在仅限Maven构建。
