First, there is red in front of the project! That indicates that the path to the package in the Classpath in the project is wrong
Workaround:
Right-click project name BuildPath---> Configure Build paht ... , and then there are several tabs above to find the package that appears in libraries with the Red Cross in the path error. Modify the current path of the corresponding package into classpath. Then go back to Eclipse and F5 refresh the project.
My method: Under the Project Package folder mvn Eclipse:clean then mvn eclipse:eclipse, go back to Eclipse and refresh the project
Second, the project is preceded by *, indicating that the project has uncommitted content.
