如何自動從Maven依賴關係中提取內容？

Question

我想創建一個基於maven的工具，當我添加一個依賴到pom.xml時，我想從下載jar文件中自動提取一些文件並將它們複製到另一個文件夾。有可能擴展Maven依賴插件嗎？任何建議表示讚賞。

Answer 1

您可以創建文件夾包含Maven Dependency Plugin和簡單的示例如下

  <plugin> 
      <groupId>org.apache.maven.plugins</groupId> 
       <artifactId>maven-dependency-plugin</artifactId> 
       <version>2.4</version> 
       <executions> 
        <execution> 
         <id>copy-dependencies</id> 
         <phase>package</phase> 
         <goals> 
          <goal>copy-dependencies</goal> 
         </goals> 
         <configuration> 
          <!-- configure the plugin here --> 
         </configuration> 
        </execution> 
       </executions> 
      </plugin> 

添加所有的依賴，你可以複製的jar文件渴望文件夾下的插件

這是一個簡單的示例，您可以用於將文件從目標中的依賴項文件夾複製到另一個文件夾中

 <plugin> 
      <!-- download from here 
      http://evgeny-goldin.org/artifactory/repo/com/goldin/plugins/maven-copy-plugin/0.2.3.8-beta-9/ 
      --> 
      <groupId>com.goldin.plugins</groupId> 
      <artifactId>maven-copy-plugin</artifactId> 
      <version>0.2.3.8-beta-9</version> 
      <executions> 
       <execution> 
        <id>create-archive</id> 
        <phase>install</phase> 
        <goals> 
         <goal>copy</goal> 
        </goals> 
        <configuration> 
         <resources> 
          <!-- ~~~~~~~~~~~~~~ --> 
          <!-- Copy resources --> 
          <!-- ~~~~~~~~~~~~~~ --> 
          <resource> 
           <targetPath>c:/YOUR_NEW_FOLDER/</targetPath> 
           <directory>${project.basedir}/target/dependency/</directory> 
           <includes> 
            <include>*.jar</include> 
           </includes> 
          </resource> 
         </resources> 
        </configuration> 


       </execution> 

      </executions> 
     </plugin>
