I need to create module in Android Studio which will contain dependency on the main project. I create new project and module, add implementation to library gradle like next:

implementation project(':app')

but when I try to sync gradle, I got next errors:

Unable to resolve dependency for ':mylibrary@debug/compileClasspath': Could not resolve project :app.

Unable to resolve dependency for ':mylibrary@debugAndroidTest/compileClasspath': Could not resolve project :app.

Unable to resolve dependency for ':mylibrary@debugUnitTest/compileClasspath': Could not resolve project :app.

Unable to resolve dependency for ':mylibrary@release/compileClasspath': Could not resolve project :app.

Unable to resolve dependency for ':mylibrary@releaseUnitTest/compileClasspath': Could not resolve project :app.

Any ideas why it happens and how to fix it?

UPDATE

here is app gradle (pretty empty)

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'

android 
 compileSdkVersion 28
 defaultConfig 
 applicationId "com.pro100svitlo.testproject"
 minSdkVersion 21
 targetSdkVersion 28
 versionCode 1
 versionName "1.0"
 testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

 minifyEnabled false

 testImplementation 'junit:junit:4.12'
 androidTestImplementation 'com.android.support.test:runner:1.0.2'

and here is library gradle:

apply plugin: 'com.android.library'
