The Jdbi library provides convenient, idiomatic access to relational databases in Java.

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

Prerequisites

Jdbi 3 requires Java 8 or better to run. Jdbi 3 requires Java 11 or better to compile.

We run CI tests against Java 11 and 17 and still support Java 8 for testing on a best-effort basis.

Java 8 compatibility

Java 8 is considered deprecated. While Jdbi does not (yet) have a specific date to drop support, please chart your path forward to a supported JDK! We recommend running the latest LTS JDK.

Jdbi 3 is compiled to Java 8 byte code and is considered stable on Java 8.

However, we now require Java 11 or better to compile as the tool chain no longer runs on Java 8.

We run CI tests on Java 8 on a best effort basis as some of the tests require Java 11+ only dependencies.

NOTE: to run on Java 8, you may need to manage the caffeine dependency back to the latest 2.x release. 3.x is necessary for newer JDKs but does not run on 8.

Builds

Jdbi is built with Apache Maven, requiring version 3.6.0 or newer.

$ ./mvnw clean install

The unit tests use Postgres and H2 databases (the tests will spin up temporary database servers as needed).

Contributing

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