Error running tomcatUnable to open debugger port (127.0.0.1 50181) java.net.B

1. Delete tomcat and rebuild one, tomcat will automatically use a port again 

2. Manually adjust the port yourself 

I use the second one, and I adjusted it manually. The initial port is: 50181, it should be 50182 , that 's it.
