Android studio : Could not find package from gitlab - android-studio

Question

I'm trying to start sample_client application of owncloud android library.
You can find the library here :
https://github.com/owncloud/android-library#:~:text=%20ownCloud%20Android%20Library%20%201%20Introduction.%20Using,code%20of%20HEAD...%204%20Compatibility.%20%20More
I changed gradle files to get packages. My problem is as follows:
Execution failed for task ':owncloudComLibrary:generateDebugRFile'.
Could not resolve all files for configuration ':owncloudComLibrary:debugCompileClasspath'.
Could not find com.gitlab.ownclouders:dav4android:oc_support_2.1.5.
Required by:
project :owncloudComLibrary
Could not find com.github.AppDevNext.Logcat:LogcatCore:2.2.2.
