0. brew install --ignore-dependencies jenkins-lts (The reson I use --ignore-dependencies is because I do not want JDK brought by brew, because I manage JDKs with SDKMAN. brew says --ignore-dependencies is deprecated, but it still does it's job)
1. adjust location of java binary at ProgramArguments section in homebrew.mxcl.jenkins-lts.plist located at:
   • /usr/local/opt/jenkins-lts/homebrew.mxcl.jenkins-lts.plist for Intel-based Macs
   • /opt/homebrew/opt/jenkins-lts/homebrew.mxcl.jenkins-lts.plist for Apple Silicon
2. brew services start jenkins-lts
3. open http://localhost:8080/
4. look up the initial password at ~/.jenkins/secrets/initialAdminPassword

Optionally: run JVM with -Dhudson.plugins.git.GitSCM.ALLOW_LOCAL_CHECKOUT=true, if you simply work locally and clone using file:// protocol

MongoDB migration: From legacy UUID represenation (binary type 3) to standard (type 4)

You may face the need to migrate your data, because legacy format was a default choice for a long time in Spring Boot/Data MongoDB and the official MongoDB driver itself (more details here).

So, here is the Java solution based on utilitites from Mongo's org.bson:bson to perform the migration.

If you develop against of containerized mongo instance using the official Docker Mongo image and make attempt to use transactions, you will most probably face the following error:

com.mongodb.MongoCommandException: Command failed with error 20 (IllegalOperation): 'Transaction numbers are only allowed on a replica set member or mongos' on server localhost:28017. The full response is {"ok": 0.0, "errmsg": "Transaction numbers are only allowed on a replica set member or mongos", "code": 20, "codeName": "IllegalOperation"}

This single docker-compose.yaml will solve the problem by creating replica set out of single node.
