第一次執行mvn clean test測試指令，發現無法如下的報錯：
[ERROR] Plugin org.apache.maven.plugins:maven-clean-plugin:2.5 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-clean-plugin:jar:2.5: Could not transfer artifact org.apache.maven.plugins:maven-clean-plugin:pom:2.5 from/to alimaven (http://maven.aliyun.com/nexus/content/groups/public/): /usr/local/software/apache-maven-3.6.3/maven-repository/org/apache/maven/plugins/maven-clean-plugin/2.5/maven-clean-plugin-2.5.pom.part.lock (No such file or directory) -> [Help 1] [ERROR] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch. [ERROR] Re-run Maven using the -X switch to enable full debug logging.

解決問題如下：
1.檢查Linux服務器maven本地倉庫中是否有下載成功的插件內容。如果沒有，可能是本地倉庫文件夾Jenkins沒有寫入的權限，使用chmod 777 filename 指令可以解決。
