apply from: 'maven_push.gradle'

Answer 1

The HoloColorPicker library has gradle tasks for uploading to the Maven repository that require some properties to be set for the gradle environment (usually in gradle.properties).

The easiest solution would be to remove the line from build.gradle:

apply from: 'maven_push.gradle'

Answer 2

I have not try the solution given by myanimal, but i have try out another thing which works with all the project which have similar issue during importing it. myanimal's solution is related to only one project, and for every project you should have to follow same thing.

But with my solution you might have to do it only once for all future projects.

For my solution do like below:

- create a file ~/.gradle/gradle.properties with the following contents:

nexusUsername=
nexusPassword=

Hope this will help you more for all projects.
