SpringBoot: can't create fully executable jar with 2.0.0-M3

Question

I have a multi module Gradle project and I tried to upgrade to 2.0.0-M3. Following the instructions here, I added this to my build script:

springBoot {
    executable = true
}

But when I build I get the following error:

Could not set unknown property 'executable' for object of type org.springframework.boot.gradle.dsl.SpringBootExtension.

Is it something broken in the milestone or am I doing something wrong?

As far as I see `executable` is removed from `2.0.0-M3` and both jar and war are executable by default. — Opal, Aug 02 '17 at 08:58
The jar file is not executable, and even if I change the permission I get an error when I try to execute it. I'm not sure how this thing should work at all, the documentation is a bit fuzzy. Max, what do you mean? I run `./gradlew build` — vforchi, Aug 02 '17 at 09:56

The configuration for this has changed in Spring Boot 2.0. Rather than configuring it on the springBoot extension, it's now configured on an individual BootJar or BootWar task. For example:

bootJar {
    launchScript {
        included = true
    }
}

As of Spring Boot 2.0 M4, this configuration has been further simplified:

bootJar {
    launchScript()
}

You may want to open an issue to correct the documentation that you linked to as it's out of date.
