Okhttp: OkHttp 3.9.0 IllegalStateException with Cookies and ProGuard

[talklittle]

Sample project: https://github.com/talklittle/TestOkHttp3.9.0

Crashes with OkHttp 3.9.0; works with OkHttp 3.8.1

Crashes with minifyEnabled true; works with minifyEnabled false

I guess ProGuard is stripping away src/main/resources/.

java.lang.IllegalStateException: Unable to load publicsuffixes.gz resource from the classpath.

Does not work: Proguard rule -keepdirectories src/main/resources/okhttp3/**

Does not work: Copying publicsuffixes.gz into app's src/main/resources/okhttp3/internal/publicsuffix/publicsuffixes.gz, even combined with above proguard rule.

Does not work: In build.gradle:

android {
    sourceSets {
        main {
            resources.srcDirs = ['src/main/resources', 'src/main/resources/okhttp3/internal/publicsuffix']
        }
    }
}

Worked: Proguard rule -keep class okhttp3.internal.publicsuffix.PublicSuffixDatabase
