Issue
I tried to use this answer to start another instance of Spring Boot
Spring Boot - how to configure port
mvn spring-boot:run -Dserver.port=8081
It gave an error
***************************
APPLICATION FAILED TO START
***************************
Description:
The Tomcat connector configured to listen on port 8080 failed to start.
It also restarted the other instance (live reload?).
Solution
It worked with
env SERVER_PORT=8081 mvn spring-boot:run
It also works with (Spring Boot 1.5.x)
mvn spring-boot:run -Drun.arguments="--server.port=8081"
