Where is --spring.output.ansi.enabled configured?

Question

I have inherited a java Spring Boot project and I'm new to most java configurations. When I run this application in debug mode the first argument passed to my application as args[0] is --spring.output.ansi.enabled=always. I have searched my project files but cannot see where this might be configured to turn off, that is I do not want it passed in as an argument. I am using the Spring STS 3.9.1 IDE.

Answer 1

In the Spring STS IDE the Debug Configuration has an option ANSI console output which was checked. Unchecking stopped the argument being passed.

Answer 2

Under Debug Configuration, uncheck the field highlighted in Red.

Answer 3

All previous answers are correct. Nevertheless, here another alternative to configure Ansi output, even though it does not answer the original question (remember, args[0] had a value): the environment variable SPRING_OUTPUT_ANSI_ENABLED=always could be set, either in the STS/Eclipse run/debug configuration (tab Environment), or otherwise for your account, or globally on your machine.

By the way, any Spring Boot configuration property can be configured via environment variables:

• either in a SPRING_APPLICATION_JSON environment variable,
• or with Binding from Environment Variables
