I thought I'd never touch Maven, JARs and Java classpaths again... I was wrong. Thank you Android for making my dev life miserable once again. 

 What are you doing?! Android should be Kotlin + Gradle... ??  

 sdkmanager stopped working, there are missing jars and some other weird stuff. I had set it up via CLI not Android Studio 

 Yeah, just go Android Studio. Everything else sucks.  

 my thoughts are with you
