在插件com.heroku.sdk找不到目標'複製'

Question

我在學習本教程（https://devcenter.heroku.com/articles/java-webapp-runner），我也在嘗試使用Heroku Maven Plugin。但是，應該有什麼問題我的pom.xml文件，命令MVN包給了我這樣的：

D:\JavaProjects\Again\helloworld>mvn package 
[INFO] Scanning for projects... 
[INFO] 
[INFO] ------------------------------------------------------------------------

這是我下面的pom.xml：

      </lifecycleMappingMetadata> 
     </configuration> 
    </plugin> 
    </plugins> 
    </build> 
</project> 

所以，我做錯了什麼，所以我甚至不能用這個POM.XML建立一個應用程序？

Answer 1

heroku-maven-plugin的<executions>部分無效。它應該看起來像這樣：

<plugin> 
    <groupId>com.heroku.sdk</groupId> 
    <artifactId>heroku-maven-plugin</artifactId> 
    <version>1.1.3</version> 
</plugin>
