Spring Boot - Clicking on Debug on Intellij gives NoSuchMethodError

[Rt Shenoy]

Hello,

I am working on Spring Boot and getting NoSuchMethodError when I click on Debug.
Apparently it is caused by multiple slf4j bindings in the classpath.
It all happened all of a sudden and I am not able to fix this for over a week now.

Please see the attached stacktrace.

My maven dependency tree is pasted below showing the different loggers on the list.

What is the reason for this error ?

Do you find this stackoverflow helpful?

It says there may be a library which is using Slf4j which is  an old version and try to exclude it.

This issue is now solved.


The problem was that there was a breakpoint somewhere and I just had to delete all the breakpoints.


I removed all breakpoints and now everything is fine.


To remove all breakpoints in IntelliJ Idea press following sequence of shortcuts: Ctrl + Shift + F8 (open Breakpoints dialog) Ctrl + A (select all breakpoint) Alt + Delete (remove selected breakpoints) Enter (confirm)
