Maven - 替换 Jar 中的文件

我想在进行 Maven 构建时替换现有 jar/zip 文件中的文件。实现这一目标的最简单方法是什么？

对于此类任务，我最喜欢的是 maven-antrun-plugin，它为您带来了完整的 ant 功能。

您可以这样使用它：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-antrun-plugin</artifactId>
    <version>1.6</version>
    <executions>
      <execution>
        <id>repack</id>
        <phase>compile</phase>
        <goals>
          <goal>run</goal>
        </goals>
        <configuration>
          <target>
            <!-- note that here we reference previously declared dependency -->
            <unzip src="${org.apache:common-util:jar}" dest="${project.build.directory}/tmp"/>
            <!-- now do what you need to any of unpacked files under target/tmp/ -->
            <zip basedir="${project.build.directory}/tmp" destfile="${project.build.directory}/common-util-modified.jar"/>
            <!-- now the modified jar is available  -->
          </target>
        </configuration>
      </execution>
    </executions>
  </plugin>

但请记住 - 永远不要修改本地存储库中的任何文件 - 在此示例中由 ${org.apache:common-util:jar}。这样做会影响您在同一台计算机上进一步构建所有项目（=针对同一本地存储库）。

此类构建在其他机器上也是不可重现（或难以重现）的。

My favorite for this sort of tasks is maven-antrun-plugin which brings you complete ant functionality.

You can use it like this:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-antrun-plugin</artifactId>
    <version>1.6</version>
    <executions>
      <execution>
        <id>repack</id>
        <phase>compile</phase>
        <goals>
          <goal>run</goal>
        </goals>
        <configuration>
          <target>
            <!-- note that here we reference previously declared dependency -->
            <unzip src="${org.apache:common-util:jar}" dest="${project.build.directory}/tmp"/>
            <!-- now do what you need to any of unpacked files under target/tmp/ -->
            <zip basedir="${project.build.directory}/tmp" destfile="${project.build.directory}/common-util-modified.jar"/>
            <!-- now the modified jar is available  -->
          </target>
        </configuration>
      </execution>
    </executions>
  </plugin>

But remember - never modify any files in your local repository - in this example pointed to by ${org.apache:common-util:jar}. Doing so would affect your further builds of all your projects on the same computer (= against the same local repo).

Such builds are also irreproducible (or hard to reproduce) on other machines.
