FAILURE: Build failed with an exception.
* Where:
Build file '/home/vagrant/build/de.rampro.activitydiary/app/build.gradle' line: 21
* What went wrong:
Plugin [id: 'com.github.triplet.play'] was not found in any of the following sources:
- Gradle Core Plugins (plugin is not in 'org.gradle' namespace)
- Plugin Repositories (plugin dependency must include a version number for this source)
Could you please take a look? Thanks!
