Are you ready to dive into the world of relational databases in Java? Jdbi is a sleek, user-friendly library that provides idiomatic access to relational databases. This article will walk you through the steps to set up Jdbi, build your project, and run tests.

Prerequisites: What You Need

Before we jump into the setup, ensure you have the following prerequisites:

• Java 11 or better is required to run Jdbi.
• To build Jdbi, you will need JDK version 17 or better.
• Apache Maven 3.9 or later is necessary if you are not using the Maven Wrapper.

How to Set Up Jdbi

Getting Jdbi up and running is as simple as following these steps:

1. Building Jdbi

To build Jdbi, you can use the Apache Maven Wrapper included with the package. If you’re using your Maven installation, run the following command in your terminal:

bash
$ make install

This command will install Jdbi into your local Maven repository.

2. Running Tests

To ensure everything is working correctly, you may want to run tests:

bash
$ make tests

This will execute all unit and integration tests. Some tests will run using Postgres and H2 databases.

Code Analogies: Understanding Jdbi

Imagine you are a chef (the developer) wanting to cook a delightful recipe (your application). Jdbi acts as your sous-chef, helping you easily fetch ingredients (database records) from the pantry (database) as you combine everything into a delicious dish. It simplifies communication with the pantry, ensuring that the chef can focus more on cooking rather than scouting for ingredients!

Troubleshooting Tips

Here are some common issues you may encounter while setting up Jdbi:

• Java Version Compatibility: If you encounter errors related to Java version, make sure you’re using Java 11 or higher. Remember that older Java versions (like 8, 9, and 10) are only supported by Jdbi versions before 3.40.0.
• Docker Issues: Ensure that Docker or a compatible environment is installed and running correctly. If tests fail due to Docker issues, you can use the command make install-nodocker to skip Docker-related tests.
• Setting Environment Variables: When using podman on Linux or MacOS, ensure that the DOCKER_HOST environment variable is set properly.
• Consult Documentation: Refer to the Developer Guide for comprehensive instructions.
