Maven:从元素'plugin'开始发现无效内容

我用plagins更新了我的pom.xml并得到了错误:

 cvc-complex-type.2.4.a: Invalid content was found starting with element 'plugin'. One of      '{"http://maven.apache.org/POM/
 4.0.0":parent, "http://maven.apache.org/POM/4.0.0":description, "http://maven.apache.org/POM/4.0.0":prerequisites,

这是pom.xml文件:
