Automatically accept all SDK licences

Question

Since gradle android plugins 2.2-alpha4:

Gradle will attempt to download missing SDK packages that a project depends on

Which

Answer 1

I finally found a solution on Windows, to have a real silent and automatic install:

On Windows, the following syntax doesn't work:

echo y | sdkmanager --licenses

It seems the "y" aren't correctly sent to the java program called in the batch.

The workaround is to create a file file-y.txt with several "y", one by line, and to use

call sdkmanager --licenses < file-y.txt

This will create the needed files in the licenses directory. The problem is probably related to the use of BufferedReader in Java
