【问题描述】：
当我使用 Tomcat 管理器在 Tomcat 服务器上部署我的应用程序时，我之前触发了新的异常。
Tomcat 错误没有明确的例外：它只说（法语中的对不起）
ECHEC - L'application pour le chemin de contexte [/api] n'a pas pu être démarrée
ECHEC - L'exception [org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/api]]] a été rencontrée
我的应用程序（和战争）是有效的（在其他服务器和我的开发工作站上运行）。
当我在 jenkins 中使用构建过程进行部署时，错误不再明确
ERROR: Build step failed with exception

Build step 'Deploy war/ear to a container' marked build as failure
我发现的唯一线索是在catalina.out日志中：
06-Aug-2020 11:50:16.185 WARNING [http-nio-8080-exec-43] org.apache.catalina.loader.WebappClassLoaderBase.clearReferencesJdbc The web application [api] registered the JDBC driver [org.postgresql.Driver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.

我试过删除war和webapp目录，重启tomcat，没有用
