如果有一天..你在配置maven环境变量后出现了错误:ERROR: JAVA_HOME is set to an invalid directory.....请一定记得....移........除......JAVA_HOME.....变量值..........末尾的那.......个..............分号";"!! 卒.
JAVA_HOME=C:\Program Files\Java\jdk1.8.0_91
M2_HOME=E:\apache-maven-3.3.9
Path=%M2_HOME%\bin
直接运行报错： No plugin found for prefix 'jetty' in the current project and in the plugin groups
如果需要使用jetty:run,那么必须在maven的setting.xml下配置
<pluginGroups>
<pluginGroup>org.mortbay.jetty</pluginGroup>
</pluginGroups>
