android - getting issues while adding other gradle project as library -

actually have been trying import gradle project library github , know there 2 ways that

1)by adding url dependencies in build.gradle file method gave lot of errors

2)manually download library , import module, add dependencies

and somehow succeeded using second method ..

after gradle sync worked correctly while running application gives bizzare errors like

error:(23, 0) gradle dsl method not found: 'ompile()' possible causes:

the project 'appintro' may using version of gradle not contain method. open gradle wrapper file

the build file may missing gradle plugin. apply gradle plugin

and github link follows

https://github.com/paolorotolo/appintro

i imported folder called library in that....

you can add library in many ways:

• add simple dependency in build.gradle file

just use:

dependencies {   compile 'com.github.paolorotolo:appintro:3.4.0' } 

• use jitpack plugin

just add repo build.gradle

repositories {         // ...         maven { url "https://jitpack.io" }     } 

and dependency:

dependencies {         compile 'com.github.user:repo:tag'     } 

• download module (the library folder) locally.
