thufir@dur:~/NetBeansProjects/HelloMaven$ tree

推荐答案

您的错误消息显示exec-maven-plugin无法找到主类.您的pom似乎没有将其列为插件. 对于完整的程序包名称，请不要包括src.main.java，而应从域开始.通常是com，org等.

Your error message says that exec-maven-plugin couldn't find the main class. Your pom doesn't seem to have that listed as a plugin. For the full package name, don't include src.main.java, just start with the domain. Which is usually com,org,etc.
