Answer 1

PullToRefresh/build.gradle applies the gradle-mvn-push.gradle plugin, but in your project you don't need/want that. If you comment out the line:
apply from: 'https://raw.github.com/chrisbanes/gradle-mvn-push/master/gradle-mvn-push.gradle'
your project should build successfully.

Answer 2

Your gradle.properties seems to be missing a GROUP property, which is required by gradle-mvn-push.gradle (see its GitHub page).

Answer 3

The original source code has gradle.properties file which contains values for all the properties you need to copy that too...
