EmptyClassBlock lint complaint on Json TypeToken

Question

I have a piece of kotlin code as below,

gson.fromJson<Map<String, JsonElement>>(data, 
   object : TypeToken<Map<String, JsonElement>>() {}.type)

Detekt doesn't like it and complaint EmptyClassBlock - [<UnknownName>]

Is there any way I could resolve that?

Either suppress your static anlysis tool or use TypeToken.getParameterized. — Eric Cochran, Jan 16 '18 at 01:57

It can be suppressed by annotating the code with @Suppress("EmptyClassBlock") (Described here)

Here’s the list of rule ids, one of which has to be passed an an argument to the annotation (EmptyClassBlock in your case).

Thanks. I know the suppression. I'm just checking if there's a way to do it without need to suppress it. – Elye Jan 16 '18 at 02:37

It’s such a rare case, suppression is fine imho – s1m0nw1 Jan 16 '18 at 02:44

This exact case was removed from the EmptyClassBlock rule in this PR: https://github.com/arturbosch/detekt/pull/665

It should be available in the latest detekt release (RC6-2) already. After updating detekt you shouldn't need to manually @Suppress these cases (objects of abstract classes) anymore.
