build.gradle 중복 라이브러리 문제

dependencies {
// compile fileTree(include: ['*.jar'], dir: 'libs')
implementation project(':MPChartLib')
implementation fileTree(include: ['*.jar'], dir: 'libs')
androidTestImplementation('com.android.support.test.espresso:espresso-core:2.2.2', {

dependecies에서 library를 추가해줄 때

implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:design:28.0.0'
implementation 'com.android.support:recyclerview-v7:28.0.0'

 

28.*.*의 버젼을 맞춰주지 않으면 appcompat 또는 support library에서 중복적으로 사용되는

라이브러리로 인하여 빌드시에 충돌이 일어난다.
