I recently installed the latest Canary build of Android Studio which is currently using the Android Gradle plugin 3.0.0-alpha4 .
I now get a error:
E
Today I also had the same problem after migrating to Android Studio 3. The problem is the gradle is not able to resolve the certain libraries due to network issue. The reasons might be various. If you work behind the proxy you need to add the proxy parameters in gradle.properties file:
systemProp.http.proxyHost=
systemProp.http.proxyPort=
systemProp.https.proxyPort=
In my case I had one more issue. My company uses the self signed SSL certificate so the SSL connection had some problem. If same applies also for you, you can set the parameter again in gradle.properties file as follows:
org.gradle.jvmargs=-Djavax.net.ssl.trustStore="/usr/lib/jvm/java-8-oracle/jre/lib/security/cacerts" -Djavax.net.ssl.trustStoreType=JKS -Djavax.net.ssl.keyStorePassword=changeit
To be more clear you can click on "Show details" link in messages log in Android Studio. This log will be more helpful to decide what is the real problem.
