Building from sources

Starting version 2.0.0-SNAPSHOT.210 building Spine modules requires JDK 17.

Versions of the v1.x family could be built with JDK 8.

Gradle is used as a build and dependency management system.

This repository uses configuration files shared across several Spine libs. They are plugged in as a Git submodule. Use the following command to initialize it:

git submodule update --init --recursive

Also, a script called pull in the root of the core-jvm project which can be used to update to the latest version of the configuration files.

Important warnings

• The code annotated with @Internal are not parts of public API of the framework. Therefore, such API should not be used from the outside of the framework.

• The public API marked as @Experimental may be used at own risk; it can change at any time, and has no guarantee of API stability or backward-compatibility.

• The API annotated with @SPI is for those who intend to extend the framework, or provide custom storage implementations.

If you need to use API with one of these annotations, please contact us.
