Jitpack.io: Task 'install' is ambiguous in root project

[budowski]

1. Trying to build this Android library: https://github.com/budowski/android-maps-utils
2. This is just a forked version of: https://github.com/googlemaps/android-maps-utils
3. The output of gradlew install:
   Task 'install' is ambiguous in root project 'android-maps-utils'. Candidates are: 'installDebug', 'installDebugAndroidTest'.
4. Looking at a similar closed issue (#19), it seems that the error is caused by android-maven plugin not being installed.
5. However, the plugin is installed (as instructed here: https://jitpack.io/docs/BUILDING/)
   See here:
   https://github.com/budowski/android-maps-utils/blob/master/build.gradle#L27
   https://github.com/budowski/android-maps-utils/blob/master/library/build.gradle#L2
   https://github.com/budowski/android-maps-utils/blob/master/demo/build.gradle#L2

Managed to work it out by looking at other forks of android-maps-utlis that used jitpack.
Still getting the same error locally, though.

Worked for me after adding the classpath to root gradle and applying plugin to the library

classpath 'com.github.dcendents:android-maven-gradle-plugin:2.1'

apply plugin: 'com.github.dcendents.android-maven'

I'm having the same issue, but it didn't occur before. How come?

I got it here on v3 here, but not on the older version, v2 :
https://jitpack.io/#AndroidDeveloperLB/ArcAnimator/

Only after adding what "EbenezerGH" wrote, it worked fine (published on v6) ...

What's so special about this? I never had to add this before...
