Hey, I'm just starting to learn to code Java, but having hard time with one error in Android Studio.
So I was following simple lesson to copy text to console, but getting error:


FAILURE: Build failed with an exception.
* Where:
Initialization script 'C:\Users\elvij\AppData\Local\Temp\Helloworld_main__.gradle' line: 20

I have this exact problem also. I'm a new java programmer coming from Netbeans IDE. What is the issue? Have you found a solution?

Can you share your code?
Use code tags to wrap it:

[code]
> your code here
[/code]

Same problem here.
I started the first project and everything still working fine. I updated Android studio and when i start a new project (No activity) I get that output.
As FoxRio, i reinstalled Android Studio and, the old 1st project can be opened and run witouth exception, when i try to start a new one i cannot.
