Getting unresolved reference error in Kotlin Android Library Project

Android

I am getting unresolved reference error in Kotlin Android Library project.

1.) standard_kotlin_lib.jar → contains: Kotlin classes, META-INF/standard_kotlin_lib.kotlin_module
2.) A.aar → compiles only standard_kotlin_lib.jar file. After compilation, inside generated A.aar file’s classes.jar: META-INF/standard_kotlib_lib.kotlin_module is missing, infect whole META-INF is missing
3.) B.aar → compiles A.aar. Here, kotlin source code importing classes define in “standard_kotlin_lib.jar”. Getting unresolved reference error at import

B.aar ← A.aar ← standard_kotlin_lib.jar

Tools Version:
1.) I am using android gradle plugin 3.0.0 and gradle version 4.3.0. With previous plugin version i.e. 2.2.3 and gradle version 3.2.1, this error was not coming. Kotlin version is 1.1.4

Issue I think:
1.) META-INF is missing inside A.aar file. When I manually copy the META-INF inside A.aar’s classes.jar, B.aar compiled successfully.
