如何在彙編後執行FTP上傳任務：在Maven中單個執行？

Question

我正在使用下面顯示的pom.xml文件使用mvn assembly:single構建特定的JAR文件（myproduct-1.0-SNAPSHOT-jar-with-dependencies.jar）。

我希望能夠通過FTP上傳該文件，如another question中所述。

添加以下代碼部分，以便能夠做到使用mvn install:install上傳：

<plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-antrun-plugin</artifactId> 
    <version>1.7</version> 
    <executions> 
     <execution> 
      <phase>install</phase> 
      <goals> 
       <goal>install</goal> 
      </goals> 
     </execution> 
    </executions> 
    <configuration> 
     <target> 
      <property name="file_name" value="myproduct-1.0-SNAPSHOT-jar-with-dependencies.jar" /> 
      <ant antfile="${basedir}/build.xml"> 
       <target name="upload" /> 
      </ant> 
     </target> 
    </configuration> 
</plugin> 

我得到的錯誤Failed to execute goal org.apache.maven.plugins:maven-install-plugin:2.3.1:install (default-cli) on project ...: The packaging for this project did not assign a file to the build artifact -> [Help 1]。

如何通過FTP上傳由mvn assembly:single生成的文件（或者使用單獨的調用，或者在生成myproduct-1.0-SNAPSHOT-jar-with-dependencies.jar之後）？

這裏的pom.xml文件：

你可以做到這一點使用wagon-maven-plugin及其upload-single目標。

在你的Maven的設置，你需要添加一個server declaration，這將申報憑據連接到您的FTP服務器：

<server> 
    <id>my-server-id</id> 
    <username>my-user-name</username> 
    <password>my-password</password> 
</server> 

然後你需要配置插件使用此服務器上傳文件。 Wagon與多個通過擴展添加的提供商合作：在這種情況下，我們需要添加wagon-ftp提供商。

<project> 
    [...] 
    <build> 
    [...] 
    <extensions> 
     <extension> 
     <groupId>org.apache.maven.wagon</groupId> 
     <artifactId>wagon-ftp</artifactId> 
     <version>2.10</version> 
     </extension> 
    </extensions> 
    [...] 
    <plugins> 
    <plugin> 
     <groupId>org.codehaus.mojo</groupId> 
     <artifactId>wagon-maven-plugin</artifactId> 
     <version>1.0</version> 
     <executions> 
     <execution> 
      <id>upload-assembly</id> 
      <phase>install</phase> 
      <goals> 
      <goal>upload-single</goal> 
      </goals> 
      <configuration> 
      <serverId>my-server-id</serverId> <!-- references the server declaration --> 
      <fromFile>${project.build.directory}/${project.build.finalName}-${project.version}-jar-with-dependencies.jar</fromFile> 
      <url>ftp://your.remote.host/</url> 
      <toFile>remote.file</toFile> 
      </configuration> 
      </execution> 
     </executions> 
     </plugin> 
    </plugins> 
    </build> 
    [...] 
</project> 

在這個例子中，Wagone執行被綁定到install相，從而來運行它，你需要用mvn clean install推出的Maven。您可能希望根據您的要求將其綁定到另一個階段。
