如何在構建結束時從Maven的目標目錄中刪除特定的目錄？

Question

我有一個任務來解壓pom.xml中提到的所有jar文件，然後將解壓後的內容打包到一個jar文件中。我能夠使用依賴插件和jar插件的解壓縮依賴目標來完成此操作。 但是，在我生成新的jar之後，我想要刪除解壓後創建的文件夾。我在我的pom.xml中使用了以下代碼片段（請閱讀每個插件上方的註釋）。

<build> 
    <plugins> 
    <!-- This part of the code is used to unpack all the dependencies mentioned in my pom.xml --> 
     <plugin> 
     <groupId>org.apache.maven.plugins</groupId> 
     <artifactId>maven-dependency-plugin</artifactId> 
     <version>2.10</version> 
     <executions> 
      <execution> 
      <id>unpack-dependencies</id> 
      <phase>package</phase> 
      <goals> 
       <goal>unpack-dependencies</goal> 
      </goals> 
      <configuration> 
       <includes>**/*.class</includes> 
       <outputDirectory>${project.build.directory}/alternateLocation</outputDirectory> 
       <overWriteReleases>false</overWriteReleases> 
       <overWriteSnapshots>true</overWriteSnapshots> 
      </configuration> 
      </execution> 
     </executions> 
     </plugin> 

     <!-- This part of the code is used for creating a jar with all the contents of the "alternateLocation" directory above --> 
     <plugin> 
      <groupId>org.apache.maven.plugins</groupId> 
      <artifactId>maven-jar-plugin</artifactId> 
      <version>2.4</version> 
      <executions> 
       <execution> 
        <phase>package</phase> 
        <goals> 
         <goal>jar</goal> 
        </goals> 
        <configuration> 
         <classesDirectory>${project.build.directory}/alternateLocation</classesDirectory> 
         <outputDirectory>${project.build.directory}</outputDirectory> 
         <finalName>abc</finalName> 
        </configuration> 
       </execution> 
      </executions> 
     </plugin> 

     <!-- I am using this part of the code to delete the "alternateLocation" after everything is done, but it deletes the target directory instead --> 
     <plugin> 
      <artifactId>maven-clean-plugin</artifactId> 
      <version>3.0.0</version> 
      <executions> 
       <execution> 
        <id>auto-clean</id> 
        <phase>install</phase> 
        <goals> 
         <goal>clean</goal> 
        </goals> 
        <configuration> 
         <filesets> 
          <fileset> 
           <directory>${project.build.directory}/alternateLocation</directory> 
          </fileset> 
         </filesets> 
         <excludeDefaultDirectories>${project.build.directory}</excludeDefaultDirectories> 
        </configuration> 
       </execution> 
      </executions> 
     </plugin> 
    </plugins> 
    </build> 

乾淨的插件基本上是在默認情況下刪除目標目錄。 那麼，如何從構建結束時的目標目錄中刪除「alternateLocation」文件夾。 （我猜你可以用maven-antrun-plugin來做，但我不想用這個插件。）。

Answer 1

您可以通過預定義的描述符jar-with-dependencies可以通過以下進行使用maven-assembly-plugin解決了這個：

<project> 
    [...] 
    <build> 
    [...] 
    <plugins> 
     <plugin> 
     <artifactId>maven-assembly-plugin</artifactId> 
     <version>2.6</version> 
     <configuration> 
      <descriptorRefs> 
      <descriptorRef>jar-with-dependencies</descriptorRef> 
      </descriptorRefs> 
     </configuration> 
     <executions> 
      <execution> 
      <id>make-assembly</id> 
      <phase>package</phase> 
      <goals> 
       <goal>single</goal> 
      </goals> 
      </execution> 
     </executions> 
     </plugin> 
     [...] 
</project> 

比你並不需要補充的配置。
