我想将基于tomcat的Web应用程序部署到heroku主机上。所以我按照这个链接给出的方法：https://devcenter.heroku.com/articles/java-webapp-runner。所以这是我的pom.xml：

问题是，当我运行“mvn package”时，我得到一个错误：
[INFO] --- maven-dependency-plugin：2.3：copy（默认）@sms-service --- [警告]注入错误：org.apache.maven.plugin.dependency.fromConfiguration.CopyMojo java.lang.NoClassDefFoundError：org / codehaus / plexus / archiver / ArchiverException
和此：
[错误]无法执行目标org.apache.maven.plugins：maven-dependency-plugin：2.3：复制（默认）项目sms-service：目标的执行默认值org.apache.maven.plugins：maven- dependency-plugin：2.3：复制失败：执行org.apache.maven.plugins时缺少必需的类：maven-dependency-plugin：2.3：copy：org / codehaus / plexus / archiver / ArchiverException
以下是我从运行“mvn package -X”获得的一些输出：

有什么问题？其实我不是maven的专家，但我认为有些奇怪。任何的想法？谢谢！
答案 0 :(得分：0)
您不应该将webapp-runner作为依赖项 - 仅复制到target/阶段的package目录中。尝试将其从<dependencies>元素中删除或将其标记为provided。
另外，请尝试将maven-dependency-plugin升级到2.10或更近期的内容。
这是sample app，可以完成你想要做的事情。
答案 1 :(得分：0)
我也遇到了同样的错误。 从 maven 中删除以下文件夹后，
1.\.m2\repository\org\apache\maven
2.\.m2\repository\org\codehaus
试试： mvn 清洁包
maven 全新下载依赖项并且运行良好。
