bootBuildImage fails with Unable to parse image reference in RC1

[tompson]

I have the following configuration in my build.gradle:

bootBuildImage {
	imageName = "eu.gcr.io/company/imagename"
	builder = "paketobuildpacks/builder:tiny"
	if (System.getenv("IMAGE_TAGS")) {
		tags = (System.getenv("IMAGE_TAGS").split(",") as List<String>).collect { "$imageName:$it" }
	}
}

which worked in 3.0.0-M5 but does not work in 3.0.0-RC1 - where it throws the following error:

Execution failed for task ':bootBuildImage'.
> Unable to parse image reference "task ':bootBuildImage' property 'imageName':test". Image reference must be in the form '[domainHost:port/][path/]name[:tag][@digest]', with 'path' and 'name' containing only [a-z0-9][.][_][-]

Thanks for trying RC1.

imageName on bootBuildImage is now a Gradle Property. Unfortunately that means that "$imageName:$it" no longer works as $imageName is the property not its value. This works:

bootBuildImage {
	imageName = "eu.gcr.io/company/imagename"
	builder = "paketobuildpacks/builder:tiny"
	if (System.getenv("IMAGE_TAGS")) {
		tags = (System.getenv("IMAGE_TAGS").split(",") as List<String>).collect { "${imageName.get()}:$it" }
	}
}

The switch to using Property is mentioned in the release notes but we hadn't anticipated that it would have this effect. We'll update the release notes.

I have updated the release notes. Thanks for bringing this to our attention.
