Reason:
[root@yuren interphone]# ps -ef|grep interphone-admin.jar
root     29204 28182 10 08:34 pts/0    00:00:26 java -jar interphone-admin.jar
It’s already running
java -jar ***.jar When the log comes out, pressing enter doesn’t actually end the process, so starting it again will report this error. After reinstalling jdk, it must not be running anymore, and it must be OK to start the project again.

Solution:
ps -ef｜grep ***.jar to find the process number
Kill the process, then restart the project.
