java - 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，并且想要从相邻模块中提取一个目录及其子模块，并在构建当前模块时将内容复制到目标目录。

我想知道获取目录指令中相邻人员的相对路径的最佳方法。

尝试

您不必声明 maven-resources-plugin 的执行明确地。它可以在 default-resources 内实现，简化POM。执行，以及:

  <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.”。所以，../adjacent/src/...没问题。

这还有一个优点，即 Eclipse m2e 插件会考虑这些声明，即资源在 Project → Clean... 中复制，而不是仅在 Maven 构建期间复制。
