执行Maven打包时候报错如下:

仔细检查后发现因为公司给这个项目配置的maven私服不一样的，在引入eclipse后选择不一样User Settings文件，如下图：

而通过CMD打包时候，默认用apache-maven-3.5.2/conf/settings.xml为配置文件的。
为此我们可以在打包命令中加入 --settings D:\soft\apache-maven-3.5.2\conf\settings_custom.xml 以指定本次打包所使用的配置文件，完整打包命令如下：

mvn clean package --settings D:\soft\apache-maven-3.5.2\conf\settings_custom.xml -DskipTests

Maven命令行窗口指定settings.xml
