BitcoindService.scala:73: error: value writeString is not a member of object java.nio.file.Files

[mdance]

I am following the build instructions at https://github.com/ACINQ/eclair/blob/master/BUILD.md

When running mvn package crashes with:

You probably need to use java 11, not java 8.

Thanks for the nod, my jenv local was showing java 11, but my jenv init line was commented out so it wasn't actually activating lol
