Compile scalachess module ( chess variants ) and replace compiled library in lila engine ?

[sensorlife]

Please help! How I can compile scalachess ( chess variants ) and replace compiled library in lila engine ?

[schlawg]

Run sbt publishLocal in your cloned scalachess repo. Subsequent lila compiles on that same machine should then use the local one (I believe as long as the versions match).

Thank you very much! I did it and it works!
But how in main lila project I can refresh ivy cache with new library ?

[schlawg]

The ivy cache is shared between the two projects. It is stored per user in ~/.ivy2

[sensorlife]

So what should I do in lila project to view my changes in scalachess project ?

[sensorlife]

I added new compiled library :
val chess = "org.lichess" %% "scalachess" % "14.0.0-RC6"

But then I compile lila i get this Errors:

Can you see changes here: https://github.com/lichess-org/lila/pull/12155/files?

If not, sorry I can't help.

[sensorlife]

I'll try to do it. I want to add new chess variant. Is it possible to do on lichess website or I need to run my own server ?

[lenguyenthanh]

currenlty, lichess doesn't have plan to add new chess variant. So, you can run your own or contribute to other like: https://www.pychess.org/

I made changes according this files ( https://github.com/lichess-org/lila/pull/12155/files ) and lila run OK ! Thank you very much !!!!

I try to write my own variant. For studying I take logic from chess.variant.KingOfTheHill and place it to chess.variant.Atomic class.
After it I publishLocal and rebuild lila. I see that Atomic coninue to remove figures after attack, but the win rule is changed. How I can replace all logic ?
