The windows-latest label is migrated to Visual Studio 2026 by default
- Update jar-pack.sh to move the pre-compiled binaries under src/main/resources - Remove logic repacking or replacing the JARs - Execute the tests immediately after compiling the libraries - Add a final deploy step including publication and GitHub release
See https://jreleaser.org/guide/latest/examples/maven/maven-central.html and https://central.sonatype.org/publish/requirements/ - Build javadoc and sources - Add publication step with a populated POM (scm, developers, license...) - Add jreleaser section allowing to publish releases and snapshots
- run ./gradlew publish jreleaserDeploy on push events only - expose the environment variables allowing to sign and deploy SNAPSHOTs and releases

Note that as per ed458f4, the publication to Maven Central is not tested in a PR workflow. As a proof-of-concept, I set up secrets on my fork to populate the environment variables defined in the deploy step using a token on Maven Central and my GPG key. The result has been deployed to Maven Central as a SNAPSHOT with the following stack trace - see https://github.com/sbesson/libjpeg-turbo-java/actions/runs/27813184919 The published SNAPSHOT has been consumed in a loca build of diff --git a/build.gradle b/build.gradle

There was a problem hiding this comment.
I don't see anything concerning in the diff. I tested including the snapshot in bioformats2raw as described, and could successfully convert CMU-1.ndpi on Windows and Linux as expected.
Discussed separately with @sbesson that getting the publication workflow to run correctly still requires some configuration, but defer to @chris-allan on that.
