Build Init Plugin "java-library" doc

In the Gradle 2.3 doc, section 47.3.2, 2nd bullet:

Uses the “mavenCentral” dependency repository

Recommend change to

Uses the “jcenter” dependency repository

This is the behavior that I am seeing.

Thanks for reporting this. This will be fixed in the documentation for Gradle 2.4.

thanks for raising this. it is indeed wrong in the documents. we missed to
change it when we moved the templates to jcenter. will fix it later today.
