The documentation at https://docs.spring.io/spring-boot/docs/current/reference/html/deployment-install.html says:

To customize written elements, use the embeddedLaunchScriptProperties option of the Spring Boot Maven or Gradle plugins.

There is no embeddedLaunchScriptProperties property in Gradle plugin. Affected versions: Spring Boot 2.

Thanks for the report. We missed updating that piece of the documentation when the Gradle plugin was rewritten in Spring Boot 2.0. You can find up-to-date documentation for configuring the launch script here.
