RELEASE.md

Releasing the project

Make version

1. Update CHANGELOG.md file

2. Set release version in 'build.gradle'

• remove "-alphaN" qualifier for the 'version' property.

3. Build and release JVM artifacts to Maven Central

a) Upload to the Nexus staging repository:

• ./gradlew :plot-api:publishAllPublicationsToMavenRepository
• ./gradlew publishLetsPlotKotlinGeoToolsPublicationToMavenRepository

Check artifacts are uploaded to the Nexus staging repository:

https://oss.sonatype.org/index.html#stagingRepositories

In the "Content" tab enter ‘Path lookup’: org/jetbrains/lets-plot

Note: check SNAPSHOT artifacts at:

https://oss.sonatype.org/index.html#view-repositories;snapshots~browsestorage

b) Publish all artifacts to the Nexus "Releases" repository (from the staging):

• ./gradlew closeAndReleaseRepository

Check artifacts lets-plot-kotlin-[jvm, js, kernel, metadata, geotools] are uploaded to the Nexus Releases repository:

https://oss.sonatype.org/index.html#view-repositories;releases~browsestorage

In the "Browse Storage" tab enter ‘Path lookup’: org/jetbrains/lets-plot

Note: PGP signature is required for publishing.

See:

• https://central.sonatype.org/pages/working-with-pgp-signatures.html
• build_settings.template.yml

Note: Individually Lets-Plot Kotlin API artifacts can be published with commands:

• "Kotlin kernel":

• ./gradlew publishLetsPlotKotlinKernelPublicationToMavenRepository

• Multi-platform:

• ./gradlew :plot-api:publishKotlinMultiplatformPublicationToMavenRepository

• ./gradlew :plot-api:publishJvmPublicationToMavenRepository

• ./gradlew :plot-api:publishJsPublicationToMavenRepository

• ./gradlew :plot-api:publishMetadataPublicationToMavenRepository

4. Prepare to the next dev cycle

• increment the version and add "-alpha1" qualifier (The 'version' property in 'build.gradle')
• push the new dev version to GitHub.

5. Re-generate the API Reference (HTML)

• ./gradlew dokka
• push the new version to GitHub with the "Reformat code" and "Update copyright" flags ON during the commit.

Update Lets-Plot library descriptor in Jupyter Kotlin Kernel

• Edit lets-plot.json and lets-plot-gt.json in the kotlin-jupyter-libraries GitHub project.

• Create a PR and get it merged into 'master'.

Note: the new descriptor will become the default only with the next release of the Kotlin Kernel. Until then, the %useLatestDescriptors line magic must be included in notebooks.

Release demo notebooks

1. Edit binder/environment.yml file.

This is optional - needed only if newer version of 'kotlin-jupyter-kernel' is required.

2. Update demo notebooks

• move from 'docs/examples/jupyter-notebooks-dev' to 'docs/examples/jupyter-notebooks'.
• Make sure the %useLatestDescriptors line magic is present.
• Remove parameters in the %use lets-plot line magic.
• Re-run all notebooks.

3. Push the updated demo notebooks and add "demo-tag":

git add --all && git commit -m "Updated demo notebooks, add v1.2.3demos1 repo tag" && git push

git tag v1.2.3demos1 && git push --tags

In docs/README.md update the Binder link with new "demo" tag (above).

Add the GitHub release:

• Open the link: https://github.com/JetBrains/lets-plot-kotlin/releases/new
• Fill Tag version and Release title with the released version: "vX.X.X"
• Fill the description field - copy from the CHANGELOG.md
