I have been trying to create app engine module using java.It has been working well .But now it suddenly start to show error
Error:Execution failed for task \
I had the same issue and I fixed it by specifying the proxy settings in gradle.properties file. Next to backend build.gradle file, I've created gradle.properties file and put there this:
systemProp.http.proxyHost= systemProp.http.proxyPort=
Specifying the proxy properties in Studio did not help me.
