Spring boot + gradle pass comand line args to application.property

Question

I use Spring Boot with Gradle, I execute this in Intelij:

10:43:37: Executing external task 'bootRun  -Drun.arguments="--
server.port=6666"'...

but still in logs I see:

Tomcat initialized with port(s): 8080 (http)

I have seen this, but it does not work for me: https://stackoverflow.com/a/37053004/3871754

Answer 1

Using Command Line Arguments with the Spring Gradle BootRun task isn't readily apparent. Here is a very interesting discussion on the topic in this Spring Boot Issue Thread.

How you can do it today is by passing all system properties to the bootRun task as mentioned in the thread, like this.

bootRun {
    systemProperties = System.properties
}

Then you can use simply:

bootRun -Dserver.port=6666
