com.google.firebase：firebase-和com.google.android.gms：play-services反编译类而不是源代码

Question

我正在使用Android Studio 3.0，我将以下库添加到gradle中：

    compile 'com.google.android.gms:play-services-gcm:11.6.0'
    compile 'com.google.android.gms:play-services-maps:11.6.0'
    compile 'com.google.android.gms:play-services-ads:11.6.0'
    compile 'com.google.android.gms:play-services-auth:11.6.0'
    compile 'com.google.firebase:firebase-database:11.6.0'
    compile 'com.google.firebase:firebase-auth:11.6.0'
    compile 'com.google.firebase:firebase-core:11.6.0'

但是当我跳入源代码时，我只能看到反编译的类：

private FirebaseAuth(FirebaseApp var1, zzdtw var2, zzdxh var3) {
    this.zzlzc = new Object();
    this.zzlyy = (FirebaseApp)zzbq.checkNotNull(var1);
    this.zzlza = (zzdtw)zzbq.checkNotNull(var2);
    this.zzlze = (zzdxh)zzbq.checkNotNull(var3);
    this.zzlwx = new CopyOnWriteArrayList();
    this.zzlyz = new CopyOnWriteArrayList();
    this.zzlzf = zzdxi.zzbqm();
    this.zzlzb = this.zzlze.zzbql();
    zzdwf var5;
    if(this.zzlzb != null && (var5 = this.zzlze.zzg(this.zzlzb)) != null) {
        this.zza(this.zzlzb, var5, false);
    }

}


public static Dialog zza(Activity var0, OnCancelListener var1) {
        ProgressBar var2;
        (var2 = new ProgressBar(var0, (AttributeSet)null, 16842874)).setIndeterminate(true);
        var2.setVisibility(0);
        Builder var3;
        (var3 = new Builder(var0)).setView(var2);
        var3.setMessage(zzu.zzi(var0, 18));
        var3.setPositiveButton("", (OnClickListener)null);
        AlertDialog var4 = var3.create();
        zza(var0, var4, "GooglePlayServicesUpdatingDialog", var1);
        return var4;
    }

某些函数具有正确的名称，有些函数没有，但没有函数具有文档，也没有可读的源代码

我试图回滚到版本10.2.4，但没有任何改变。
