Eclipse 创建项目时报错

使用了阿里的中央仓库，更换为public仓库解决了该问题，公共配置未修改，修改的是个人用户配置

<mirror>

	<mirrorOf>*</mirrorOf>
	<name>阿里云公共仓库</name>
	<url>https://maven.aliyun.com/repository/public</url>

Eclipse中的配置

 --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

如果上面的方式没有解决问题，可以尝试以下的方式

1. 如果maven软件本身没有问题，那么问题就出在我们的使用方式上

2. 回顾maven使用的几个要点

下载maven软件、安装并配置环境变量

修改maven的settings文件，镜像源、本地仓库等

配置Eclipse中的maven

3. 删除已有的maven配置

删除安装软件、本地仓库；如果是当你更换过本地仓库位置时，找到他们并全部删除

然后重新安装配置

4. 重新安装

C:\Users\thinkpad>mvn -v
Apache Maven 3.6.2 (40f52333136460af0dc0d7232c0dc0bcf0d9e117; 2019-08-27T23:06:16+08:00)
Maven home: E:\wks_mango\app\apache-maven-3.6.2\bin\..
Java version: 1.8.0_181, vendor: Oracle Corporation, runtime: E:\disk\app\java\jdk\jre
Default locale: zh_CN, platform encoding: GBK
OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows"

C:\Users\thinkpad>java -version
java version "1.8.0_221"
Java(TM) SE Runtime Environment (build 1.8.0_221-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.221-b11, mixed mode)

查看maven版本信息，发现maven找的JDK并不是当前JAVA_HOME配置的JDK，之前配置了多次JDK环境变更，不知为何maven找了之前的某个版本的JDK

找到M2_HOME/bin目录下的mvn.cmd文件，指定JDK的路径

set ERROR_CODE=0
set JAVA_HOME=E:\wks_mango\app\jdk8u221

这样maven就可以找到指定版本的JDK
