        jvmTarget = "1.8"
    }
}

The error clearly tells you to change the target and source compatibilities to 1.7 in a library's sub-module. Why can't just change that?

I think it probably asks you to change this:

compileKotlin {
kotlinOptions {
    jvmTarget = "1.8"
}
}
compileTestKotlin {
kotlinOptions {
    jvmTarget = "1.8"
}
}

to this:

compileKotlin {
kotlinOptions {
    jvmTarget = "1.7"
}
}
compileTestKotlin {
kotlinOptions {
    jvmTarget = "1.7"
}
}
