Failed to resolve: org.apache.directory.studio:org.apache.commons.io:2.6

I have couple of years old Android App and I'm trying to get it working now. I have already solved many problems redarding to API levels and so on, but now I'm stuck. The app earlier used API 23, now using API 28.

When I'm trying to build the app in Android Studio this error occurs: Could not find org.apache.directory.studio:org.apache.commons-io:2.6.

I understand that for some reason it cannot be downloaded. I have tried to put many repositories in build.gradle file:

mavenCentral() google() maven { url "https://github.com/rosjava/rosjava_mvn_repo/raw/master" } jcenter() mavenLocal() maven { url 'https://maven.fabric.io/public' } 

But it always say Failed to resolve.

The corresponding row in build.gradle file:

api 'org.apache.directory.studio:org.apache.commons.io:2.6' 

Also tried "implementation" instead of "api" but there's no difference.

What am I missing here? Compile SDK API 28, target SDK API 28.
