Get the latest Spring Boot version and its associated BOM versions, such as Spring Cloud, written in Go.

Usage

Input Variables

Name	Description
boot-url	URL of Spring Boot metadata (default: https://api.spring.io/projects/spring-boot/releases)
starter-url	URL of Starter metadata (default: https://start.spring.io)
insecure	true/false, allow insecure metadata server connections when using SSL (default: false)
boot-version	Spring Boot version, uses the current version if left blank. Supports semver comparison, e.g. ~3.x, see "Checking Version Constraints" for more details.
dependencies	List of dependency identifiers to include in the generated project, can separate with commas, e.g. cloud-starter
verbose	true/false, provides additional detailed outputs, often used for debugging purposes

Outputs

This action provides an output of the BOM versions managed by Spring, which includes the following:

• spring-boot
• spring-cloud
• spring-cloud-azure
• spring-cloud-gcp
• spring-cloud-services
• spring-modulith
• spring-shell
• codecentric-spring-boot-admin

• solace-spring-cloud
• testcontainers
• vaadin
• wavefron

You can refer to the outputs section of action.yml file for more details.

Example

The following example workflow fetches the latest version and then checks the current version. If it spots any differences between the two, it triggers an update and creates a pull request.

Based on the example above, the code diff for bumping Spring might look like this:
