WebSphere自由-码头映像上的共享库

Question

我正在使用websphere- have (https://hub.docker.com/_/websphere-liberty/)映像来部署我的应用程序，但是我在共享库方面有问题。我需要将jar从util项目转换为自由服务器上的共享库。我被这个错误困住了：

SchedulerApplication-加载ok -来自Scheduler应用程序，但它正在从util项目扩展类

[ERROR   ] SRVE0276E: Error while initializing Servlet [Scheduler]: 

    javax.servlet.UnavailableException: SRVE0203E: Servlet [Scheduler]: com.scheduler.SchedulerApplication was found, but is missing another required class.
    SRVE0206E: This error typically implies that the servlet was originally compiled with classes which cannot be located by the server.
    SRVE0187E: Check your class path to ensure that all classes required by the servlet are present.SRVE0210I: This problem can be debugged by recompiling the servlet using only the classes in the application's runtime class path
    SRVE0234I: Application class path=[com.ibm.ws.classloading.internal.ThreadContextClassLoader@3c27eabb]

修正了在将ear文件移出配置/下拉列表后，=>停止了自动部署

看起来app是从配置/下拉列表中安装的2x -auto部署&从server.xml部署

COPY --chown=1001:0 --from=maven_build /app/Scheduler/target/Scheduler.ear /opt/ibm/wlp/usr/servers/defaultServer/apps
