eclipse在clean maven時報錯Exception in thread "main" java.lang.UnsupportedClassVersionError: org/apache/maven/cli/MavenCli : Unsupported major.minor version 51.0：
網上查詢資料：java

一、查詢eclipse默認maven版本 (Window - Preferences - Maven - Installations) 發現 maven版本爲3.3.9apache

訪問網站：http://maven.apache.org/download.cgi
eclipse

3.3.9版本的maven 要求jdk1.7 以上版本，以後查詢了一下maven項目的jdk版本發現jdk時1.6
因此報錯maven
