Removing from Cache not working as intended?

[ABausG]

Trying to remove a Website from the Cache using Fuse.stringCache.remove(url)
url is the String of the Website I used to download.

However when using it like so I get the following Exception:

 java.lang.IllegalArgumentException: keys must match regex [a-z0-9_-]{1,64}: "https://www.wired.com/2017/11/gifts-for-the-apple-iphone-lover/"
                                                                             at com.jakewharton.disklrucache.DiskLruCache.validateKey(DiskLruCache.java:660)
                                                                             at com.jakewharton.disklrucache.DiskLruCache.remove(DiskLruCache.java:581)
                                                                             at com.github.kittinunf.fuse.core.cache.DiskCache.remove(DiskCache.kt:40)
                                                                             at com.github.kittinunf.fuse.core.Cache.remove(Cache.kt:113)
                                                                             at com.github.kittinunf.fuse.core.Cache.remove$default(Cache.kt:110)

What I tried:

1. Matching the url to the Regex - did not work as it is not the key
2. Calling it using Fuse.stringCache.remove(URL(url).toString()) also not finding the Item to remove

What worked was Fuse.stringCache.remove(url.md5()). Is that the way it is supposed to work?
Edit: This did not remove the Value from the Cache

Maybe adding a function to remove Items by URL similar to the get function would be a consideration?

Tried a bit more. The URL seems to be the right key as I get the Data when I call it with get. However using it with remove() produces the IllegalArgumentException with the wrong regex

Found my Error. I was using the 0.2.0 instead of the 0.2.0-new version. Now it works as intended.

However: Android Studio Lint Checker is recommending the 0.2.0 Version as it thinks it is newer. Don't know how to fix that.
