renovate/lib/modules/datasource/sbt-plugin/readme.md

This datasource finds SBT plugin updates from Maven repositories.

By default, Renovate:

1. Checks https://repo1.maven.org/maven2/ for SBT plugins
2. If the above URL returns no results, then Renovate tries the legacy URL: https://repo.scala-sbt.org/scalasbt/sbt-plugin-releases

You can override the default behavior with the registryUrls config option. For example:

{
  "matchDatasources": ["sbt-plugin"],
  "registryUrls": [
    "https://repo1.maven.org/maven2/",
    "https://oss.sonatype.org/content/repositories/snapshots",
    "https://repo.scala-sbt.org/scalasbt/sbt-plugin-releases"
  ]
}
