java - Sanitize version for docker image versioning. nebula.release

I have a pipeline to build a Docker image in every push to specific branches in my git repository. The problem is that semantic versioning is using '+' character to specifying the metadata section in the version name. I need to replace this char for another supported by Docker in the image name. There is any way to replace that character or use a custom version name?

I am using nebula.release to inferring the project version.

id 'nebula.release' version '10.1.1'

jib {
    to {
        image = "registry.gitlab.com.uy:5005/project/app:$version"
        auth {
            username = System.getenv('CI_REGISTRY_USER')
            password = System.getenv('CI_REGISTRY_PASSWORD')
        }
        tags = ['latest']
    }
    container {
        ports = ['8080']
        environment = [
                SPRING_OUTPUT_ANSI_ENABLED: 'ALWAYS',
        ]
        useCurrentTimestamp = true
    }
    allowInsecureRegistries = true
}

jibDockerBuild.dependsOn bootJar

This is the error:

  • What went wrong: Execution failed for task ':jib'.

    com.google.cloud.tools.jib.image.InvalidImageReferenceException: Invalid image reference: registry.gitlab.com.uy:5005/project/app:1.0.0-rc.1.dev.0+108db18

I created this task in my build.gradle file, Is there any way to reuse it?

task cleanVersion {

    ext.sanitizeVersion = { version ->
        return version.toString().replace('+', '_')
    }
    doLast {
        println sanitizeVersion("$version")
    }
} 

I could use some help. Thanks in advance for your time.

    Since build scripts are code and it looks like jib is an extension, project.version is a retrieval property (compared to a task output or something generated), you can use the same code you have in your current cleanVersion task to configure the extension.

    image = "registry.gitlab.com.uy:5005/project/app:${version.toString().replace('+', '_')}"
