I found the missing class in the org.xwiki.component.manager ,and it had already built success and installed, but the error occurred Description Resource Path Location Type The project was not built since its build path is incomplete. Cannot find the class file for org.xwiki.component.descriptor.ComponentDescriptor. Fix the build path then try building this project XWiki Commons - Legacy - Component - Default Implementation Unknown Java Problem Description Resource Path Location Type The type org.xwiki.component.descriptor.ComponentDescriptor cannot be resolved. It is indirectly referenced from required .class files LogEnabledLifecycleHandler.java /XWiki Commons - Legacy - Component - Default Implementation/src/main/java/org/xwiki/component/embed line 1 Java Problem
