Can't build for Android with error "Failed resolution of R$color" after build JAR

Question

While I run the project with an implementation project(path: ':rocket_library') then the resource (Ex: R.color.color_rocket_web) file works fine. But after building the JAR file and include the JAR with project resource not found. Is it possible to attach the resource files in a JAR?

The color not found from the project:

Library code: On runtime also not found from Libray.

import infix.imrankst1221.rocket.library.R

fun getThemePrimaryColor(mContext : Context): Int {
    return PreferenceUtils.getInstance().getIntegerValue(Constants.KEY_COLOR_PRIMARY, ContextCompat.getColor(mContext, R.color.my_color))
}

Runtime exception:

            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }

}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])

    implementation 'com.android.support:appcompat-v7:28.0.0'
    testImplementation 'junit:junit:4.12'

    implementation 'com.google.android.material:material:1.1.0-alpha06'

    implementation 'com.google.code.gson:gson:2.8.5'

}
task createJar(type: Copy) {
    from('build/intermediates/packaged-classes/release/')
    into('libs/')
    include('classes.jar')
    rename('classes.jar', 'rocket_web.jar')
}

I found a temporary solution, JAR file does not content the resource files but AAR file can. So now I am using AAR file. — Md Imran Choudhury, May 29 '19 at 07:52

Yap, I try it, even I delete all the cash file. Also, try to create a new project and import the AAR but still the same. – Md Imran Choudhury May 29 '19 at 06:37
