It seems to be in the ansi color logging in logback.xml on Windows causing problems.

Is there an easy way to enable Jansi with MN? This article Springboot logging under point 8. JANSI on Windows, describe the problem and solution.

[graemerocher]

You can simply follow the same steps as described in the referenced Spring Boot post

[zulq]

I followed that article and added Jansi as a dependency but still getting the same error. However by editing logback.xml and setting <withJansi>fasle</withJansi> the error disappears.

[graemerocher]

We will make that setting false on Windows by default

[alokkumarsinha]

On Windows 10, using VS Code with Maven and Gradle extensions installed, it is still happening and doing this (..However by editing logback.xml and setting fasle</withJansi>...) fixed the problem.
