Deploy SpringForge plugin to JetBrains Marketplace

[UdulaThathsaridu5624]

Publish the SpringForge IntelliJ IDEA plugin to the JetBrains Marketplace so that users can install it directly from the IDE plugin browser.

Tasks

• Verify plugin.xml metadata (id, name, description, change-notes, vendor, idea-version)
• Ensure plugin version follows semantic versioning (e.g., 1.0.0)
• Add publishPlugin configuration to build.gradle.kts using the IntelliJ Platform Gradle Plugin
• Generate a JetBrains Marketplace token and store it as PUBLISH_TOKEN in GitHub Actions secrets
• Add a release.yml GitHub Actions workflow that triggers on version tags (v*) and runs ./gradlew publishPlugin
• Write a Marketplace description (pluginDescription block) with screenshots and feature list
• Test the plugin against the minimum supported IntelliJ version declared in plugin.xml
• Submit for JetBrains review (first-time submissions require manual approval)

Acceptance Criteria

• Plugin is searchable and installable from Settings → Plugins → Marketplace inside IntelliJ IDEA
• CI/CD pipeline automatically publishes a new version on each tagged release
• Plugin passes JetBrains automated compatibility checks (no deprecated API usage)
