Hi,

I need some help to integrate logback into my app.
I use gradle to automate the building and this error occurs when running
"gradlew runMod" task:

[configuration ':archives', configuration ':compile', configuration
> ':default', configuration ':groovy', configuration ':provided',
> configuration ':runtime', configuration ':signatures', configuration
> ':testCompile',configuration ':testRuntime']

The sample app can be found in the attachment. Just unpack and run "gradlew
