package是报错
Cannot access nexus-aliyun (http://maven.aliyun.com/nexus/content/groups/public) in offline mode and the artifact org.apache.maven.surefire:maven-surefire-common:pom:2.22.2 has not been downloaded from it before.
根据翻译的意思：
无法在脱机模式下访问nexus-aliyun (http://maven.aliyun.com/nexus/content/groups/public)，并且之前没有从该文件下载过工件org.apache.maven.surefire:maven-surefire-common:pom:2.22.2。
解决方法：在设置找到maven的配置，取消Work_offline的勾选，再次package即可
