How to fix ch.qos.logback.classic.LoggerContext error?

I’m using logback.xml logging framework. We have very detailed tutorial on What is Logback.xml Logging Framework?

Kindly take a look if you want to learn and how to configure logback.xml file.

In short, you have to create logback.xml file and put it under /resources folder. Somehow I was missing logback-test.xml file under /resources folder.

In order to fix this error create very simple logback-test.xml file with below file content.

Create file logback-test.xml

<configuration>

</configuration>

That’s it. Rebuild your project and run your Java program. You shouldn’t see this error any more.

Hope this helps.
