With Android Studio 2.3(AS) the project works fine and i can able to run the App. After updating the AS to Android Studio 3.0. i too got the error as below for libraries and build types.
Unable to resolve dependency for ':app@dexOptions/compileClasspath': Could not resolve project : library_Name.
Unable to resolve dependency for ':app@release/compileClasspath': Could not resolve project : library_Name.
To Solve the issue, simply.
What ever the
buildTypes{
debug{ ... }
release{ ... }
}
you have in your (app) build.gradle file, You have to include all the buildTypes{ }
with same names as like
buildTypes{
debug{ ... }
release{ ... }
}
in to build.gradle
files of All libraries/modules included in project.
clean and rebuild the project, the issue will be fixed.
Still issue not fixed, update the gradle-wrapper.properties to
distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip
