这个原因是这个库在镜像里没有。当然没有啊，这是我本地别的项目的jar包
接着看我maven的配置，就是这个包找不到。
<dependency>
<groupId>Mxgraph</groupId>
<artifactId>mlcp</artifactId>
<version>1.0</version>
</dependency>
最后看代码：
mvn install:install-file -Dfile=C:\Users\Administrator\Desktop\mlcp-1.0.jar -DgroupId=Mxgraph -DartifactId=mlcp -Dversion=1.0 -Dpackaging=jar
解释一下：
-Dfile：你要添加的jar包
-DgroupId -DartifactId -Dversion：和你的maven对应起来
-Dpackaging：你添加的包的类型 |
