If you're making changes to the Scalachess library, you can have lila use it instead of the published Maven version:

1. Update the `build.sbt` file in the scalachess repo:
1. Make sure you already have lila-docker up and running, with lila currently using the published Maven version of scalachess.

2. Then, update the `build.sbt` file in the scalachess repo:

```diff
- ThisBuild / version := "15.6.7"
+ ThisBuild / version := "my-test-1" # give it a custom version
- version := "17.16.1"
- organization := "com.github.lichess-org.scalachess"
+ version := "my-test-1" # give it a custom version
+ organization := "org.lichess"
```

3. Publish your local scalachess changes:

```bash
docker compose exec -w /scalachess lila sbt publishLocal
```

2. Update the `Dependencies.scala` file in the lila repo:
4. Make any code changes you may require in lila to use your scalachess version.

5. Update the `Dependencies.scala` file in lila:

```diff
- val chess = "org.lichess" %% "scalachess" % "15.6.7"
+ val chess = "org.lichess" %% "scalachess" % "my-test-1"
object chess:
- val version = "17.16.1"
- val org = "com.github.lichess-org.scalachess"
- // val org = "org.lichess" // for publishLocal
+ val version = "my-test-1"
+ val org = "org.lichess" // for publishLocal
```

3. Publish the local scalachess changes and restart lila:
6. Restart lila:

```bash
docker compose exec -w /scalachess lila sbt publishLocal
docker compose restart lila
./lila-docker lila restart
```
