Before you choose

Requirements & limits

  • The SDK is written in Java and targets Solana development.
  • Documentation distinguishes Core utilities from RPC clients.
  • The repository lists an Apache-2.0 license.
  • Repository build instructions require a GitHub token with the read:packages scope to access dependencies hosted on GitHub Package Repository.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Configure credentials and run Sava’s Gradle checks

Set up GitHub Packages credentials for the repository and run its documented Gradle check task.

Before you start

  • A classic GitHub token with the read:packages scope.
  • A Gradle environment capable of running the repository’s ./gradlew wrapper.

Steps

  1. Generate a classic GitHub token with the read:packages scope.

  2. Add savaGithubPackagesUsername=GITHUB_USERNAME and savaGithubPackagesPassword=GITHUB_TOKEN to ~/.gradle/gradle.properties, replacing the placeholders with your credentials.

  3. From the repository, run ./gradlew check.

Expected outcome

The repository’s Gradle check task is invoked with credentials configured for dependencies hosted on GitHub Package Repository.

Guide limitations

  • This is a repository build/check procedure, not instructions for using the SDK in an application.
  • The source does not document the result of running the check task.
