These instructions worked for me on apache-tomcat-8.5.20 on mac os 10.13.3 using jdk1.8.0_152:

$ cd /path/to/apache-tomcat-8.5.20/bin
$ export JPDA_ADDRESS="localhost:12321"
$ ./catalina.sh jpda run

Now connect to port 12321 from IntelliJ/Eclipse and enjoy remote debugging.

Inside catalina bat set the port on which you wish to start the debugger  if not   JPDA ADDRESS         goto gotJpdaAddress set JPDA ADDRESS 9001   Then you can simply start the debugger with   catalina bat jpda    Now from Eclipse or IDEA select remote debugging and start start debugging by connecting to port 9001

From your IDE  create a remote debug configuration  configure it for the default JPDA Tomcat port which is port 8000   From the command line   Linux   cd apache-tomcat bin export JPDA SUSPEND y   catalina sh jpda run   Windows   cd apache-tomcat bin set JPDA SUSPEND y catalina bat jpda run  Execute the remote debug configuration from your IDE  and Tomcat will start running and you are now able to set breakpoints in the IDE    Note    The JPDA SUSPEND y line is optional  it is useful if you want that Apache Tomcat doesn t start its execution until step 3 is completed  useful if you want to troubleshoot application initialization issues
