Unable to import

Error:No such property: GROUP for class: org.gradle.api.publication.maven.internal.deployer.DefaultGroovyMavenDeployer

I got this too, so I removed this line (after updating everything possible) :

apply from: 'https://raw.github.com/chrisbanes/gradle-mvn-push/master/gradle-mvn-push.gradle'

And also deleted the ".idea" and "gradle" folders.

However, now I see this:

Error:Execution failed for task ':agendacalendarview:transformClassesWithRetrolambdaForDebug'.
> Missing javaCompileTask for variant: debug/0 from output dir: C:\Users\User\AndroidStudioProjects\AgendaCalendarView\agendacalendarview\build\intermediates\transforms\retrolambda\debug\0

As your warning says, first remove retrolambda. It's deprecated now, lambdas are supported by default now, without any 3rd party libs. Also, old ButterKnife version used may cause some problems with latest Android Studio and Gradle. Either remove ButterKnife (and use findViewById) or bump version and fix its calls (syntax is different now for some annotations)

Or just create empty project and import module (which is actually easier).
