Question

我正在学习本教程（https://devcenter.heroku.com/articles/java-webapp-runner），我也尝试使用Heroku Maven插件。但是，我的 POM.XML 文件应该有问题，所以命令 mvn package 给了我这个：

D:\JavaProjects\Again\helloworld>mvn package

以下是 POM.XML ：

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

那么，我做错了什么，所以我甚至无法使用 POM.XML 构建应用程序？

Answer 1

<executions>的{{1}}部分无效。它应该是这样的：

heroku-maven-plugin

无法在插件com.heroku.sdk
