Stop port for a certain Tomcat plug-in (8081)

Introduction

It's been a while since I've been working on a web app and another web API system that is called from it, so when I tried to launch the development environment, the web app didn't start. ~~ Docker? What is it delicious? ~~

Environment (details are unknown because it is the workplace)

• Web app
• Spring MVC (non-Spring Boot)
• Gradle
  • TomcatPlugin
• WebAPI
  • SpringBoot

What happened

1. Launch the WebAPI executable jar on port8081

• java -jar xxx.jar --server.port=8081

1. Launch the web app from the gradle task

• gradle tomcatRun

1. Does not start \ (\ ^ o \ ^) /

It seems that port is used when executed with --trace

Address already in use: JVM_Bind

But netstat/nao | findstr" 8080 " does not apply

Hate ...

What was it

As written on github, Tomcat Plugin used 8081 as the stop port of tomcat. I changed the WebAPI side to 8090 and it worked fine.

How did you notice immediately

――I should have just put out a detailed log --You shouldn't have suddenly narrowed down to 8080 with netstat --I should have searched from the port side used by WebAPI
