Workshop Requirements

You have two choices: load everything or use Codespaces and don't worry about setup

For the Load Everything Option

• JDK 25+
• IntelliJ Idea (with Scala plugin)
• Maven
• SBT
• Git

Run in Codespaces

1. Go to https://github.com/dhinojosa/thinking-functionally-jvm
2. Click the green “Code” button and select, Codespaces
3. Click the Create Codespace on main button

The following will provide you with an online application using a VS Code instance.

Attendees will need the following to do the hands-on labs:

• A laptop with power - It is strongly recommended to bring a personal laptop as corporate devices are sometimes too locked down to be able to run the labs!
• A GitHub account on the public GitHub.com (free tier is fine)
• Browser

To do the labs in this workshop, you must have a Claude Code Pro subscription already so you will have access to Claude Code. If you do not, you will not be able to use Claude Code in this workshop. See https://www.anthropic.com/pricing.

In the workshop, we will be using…

• Java 17+
• An IDE of your choosing (I will be using IntelliJ IDEA)
• OpenAI's API (you will need an account and a small amount of credit $5 is more than enough).
• Docker Desktop (and it would be helpful if you were to pull “qdrant/qdrant:latest” before arriving at the workshop.

Optionally, you may choose to use a different AI provider other than OpenAI such as Anthropic, Mistral, or Google Vertex (Gemini), but you will need an account with them and some reasonable amount of credit with them. Or, you may choose to install Ollama (https://ollama.com/), but if you do be sure to install a reasonable model (llama3:latest or gemma:9b) before you arrive.

Know that if you choose to use something other than OpenAI, your workshop experience will vary.

If you were to initialize a new Spring Boot project from the Spring Initializr (which includes some dependencies already selected), set spring.ai.openai.api-key to your OpenAI API Key, build, then run it without errors, then you are probably ready for the workshop.

You will need the following installed

• Git
• A good text editor. I highly recommend VS Code.

You can opt to run the examples on GitHub Codespaces, in which case you don't need any setup
Otherwise, if you want to run locally:

• Git
• The latest JDK (26 at the time of this writeup)
• Maven
• IDE of Choice (Prefer IntelliJ) (Please upgrade)
