Build and pipeline updates

[jjohannes]

PRs to address build and pipeline concerns

The PRs are initial proposals and may not all be integrated as they are.

Best Practices

• Gradle Best Practices build: introduce convention plugins and use Kotlin DSL #21

New build features

• Add signing: part of build: introduce convention plugins and use Kotlin DSL #21
• Add Maven Central publish: build: add Maven Central publishing #23
• Add multi-JDK build support: https://github.com/jjohannes/sava/pull/1

New build features (optional)

• Add dependency analysis: part of Introduce java-module-dependencies and remove build.gradle files #24
• Get dependencies directly from module-info / use BOM instead of Catalog: Introduce java-module-dependencies and remove build.gradle files #24
• Shared Gradle configuration: publish gradle/plugins and use it in all other repositories (https://github.com/sava-software/sava-build)
  • Add Gradle convention plugins sava-build#1
  • Use Gradle convention plugins from 'sava-build' json-iterator#2
  • Use Gradle convention plugins from 'sava-build' #25
  • Use Gradle convention plugins from 'sava-build' solana-programs#1
  • Use Gradle plugins from 'sava-build' and structure for publishing solana-version-catalog#2

Changes necessary in GitHub

Add the following org secrets.

• MAVEN_CENTRAL_USERNAME username you get from generate-portal-token
• MAVEN_CENTRAL_PASSWORD password you get from generate-portal-token
• SIGNING_KEY your signing key (ascii-armored)
• SIGNING_PASSPHRASE passphrase for the key

Open Points

• Publish a platform (BOM) together or instead of a version catalog --> Publish BOM together with catalog solana-version-catalog#1
• Add Develocity build scans (e.g. https://scans.gradle.com/s/s2hgmksw5dmim)
• Add style auto-formatting and checking (https://github.com/diffplug/spotless)? --> no
• How to publish for different JDK versions --> will be done via branches and GH actions
• Remove GithubPackages publishing altogether? Use Maven Central SNAPSHOTS (configure in CI pipeline)? --> no
• Check how/if to improve passing the javaVersion into Gradle from GH Actions now that everything in the build relies on the toolchain configuration.
