java - Maven tomcat7仅执行 war 错误

我想创建一个可执行的war / jar，如tomcat7-maven-plugin文档中所述：http://tomcat.apache.org/maven-plugin-2.2/executable-war-jar.html

但是我得到一个构建失败（NullPointerException）：

目标tomcat7：deploy，：redeploy，：undeploy和使用tomcat7：run启动本地嵌入式服务器的运行均符合预期。

与上面链接的文档不同，我只有一个.pom文件，因此我将文档中的各个部分合并在一起。我的pom现在看起来像这样：

附加信息：我使用Eclipse Kepler，我的运行配置如下所示：
tomcat7：exec-war -e
我也尝试了突击队，尝试了：exec-war-only，但是没有任何效果。

我已经搜索并尝试了几天的尝试，所以对您的帮助非常感谢！ ：]

最佳答案

我在插件的2.2版中遇到了类似的问题，但是根据this tutorial，我使用2.1来运行它。

关于java - Maven tomcat7仅执行 war 错误，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/24125378/
