The Jdbi library provides convenient, idiomatic access to relational databases in Java and other JVM technologies such as Kotlin, Clojure or Scala.

Jdbi is built on top of JDBC. If your database has a JDBC driver, you can use Jdbi with it.

Jdbi requires Java 11 or better to run.

We run CI tests against Java 11, 17 and 21.

Java 8, 9 and 10 are supported by any Jdbi version before 3.40.0.

Jdbi requires a JDK version 17 or better to build. We enforce the latest LTS (currently Java 21) for releases.

Jdbi is "batteries included" and uses the Apache Maven Wrapper. If an external Maven installation is used, Apache Maven 3.9 or later is required. Using the make targets requires GNU make.

All build tasks are organized as make targets.

Build the code an install it into the local repository:

$ make install

Running make or make help displays all available build targets with a short explanation. Some of the goals will require project membership privileges. The CONTRIBUTING.md document contains a list of all supported targets.

To add command line parameters to the maven executions from the Makefile, set the MAVEN_CONFIG variable:

% MAVEN_CONFIG="-B -fae" make install

Running make tests runs all unit and integration tests.

Some tests use Postgres and H2 databases (the tests will spin up temporary database servers as needed). Most modern OS (Windows, MacOS, Linux) and host architecture (x86_64, aarch64) should work.

For a full release build, docker or a docker compatible environment must be available. A small number of tests use testcontainers which in turn requires docker.

make install-nodocker skips the tests when building and installing Jdbi locally. make tests-nodocker skips the tests when only running tests.

Supported configurations are

• Docker Desktop on MacOS
• docker-ce on Linux
• podman 3 or better on Linux and MacOS

Other docker installations such as Colima may work but are untested and unsupported.

For podman on Linux, the podman socket must be activated (see https://stackoverflow.com/questions/71549856/testcontainers-with-podman-in-java-tests) for details. SELinux sometimes interferes with testcontainers if SELinux is active; make sure that there is an exception configured.

For podman on MacOS, it is necessary to set the DOCKER_HOST environment variable correctly.

Please read CONTRIBUTING.md for instructions to set up your development environment to build Jdbi.

Jdbi uses SemVer to version its public API.
