Answer 1

Caused by: java.util.zip.ZipException: error in opening zip file This mean that a file that Gradle has downloaded has become corrupted due to somehow or some reason. This might be the download of Gradle itself (which the wrapper does) or any dependency that Gradle has downloaded to run your build.

Gradle doesn't attempt to detect or resolve the problem, so you need to fix it manually. The solution is often to purge Gradle's download caches and let it get fresh copies of what it needs.

To do that, delete the .gradle directories in both your home directory and in your project's root directory and try building again.

In window home directory of gradle is

C:\Users\User.gradle In Mac OSX home directory

/Users/User_name/.gradle

If you still haven't figured out this problem yet, it's because you literally have no internet connection which is mandatory for gradle building since the platform checks for potential updates for say, sdk versions, from a server.

However, if you want to build and do your work offline, then go to File -> Settings -> Build, Execution, Deployment -> Gradle -> Check Offline work under Global Gradle settings
