	// The condition configures when the pipeline should trigger a new image build.
	//
	// When the `pipelineExecutionStartCondition` is set to `EXPRESSION_MATCH_AND_DEPENDENCY_UPDATES_AVAILABLE` , and you use semantic version filters on the base image or components in your image recipe, Image Builder will build a new image only when there are new versions of the image or components in your recipe that match the semantic version filter. When it is set to `EXPRESSION_MATCH_ONLY` , it will build a new image every time the CRON expression matches the current time. For semantic version syntax, see [CreateComponent](https://docs.aws.amazon.com/imagebuilder/latest/APIReference/API_CreateComponent.html) in the *Image Builder API Reference* .
