Answer 1

I've the same problem. It's graved in gradle. ( Details here http://www.mkyong.com/webservices/jax-ws/java-security-cert-certificateexception-no-name-matching-localhost-found/ )

But here is a simple solution to the problem. Just change https to http protocol in $(ProjectDir)/gradle/wrapper/gradle-wrapper.properties

change line from

distributionUrl=https://services.gradle.org/distributions/gradle-2.2-all.zip

to

distributionUrl=http://services.gradle.org/distributions/gradle-2.2-all.zip
