How to accept Gradle ToS for `build --scan` automatically and still manage to run build without a scan?

Question

I am using Gradle 4.6 which allows me to run build scans using the --scan option without having to explicitly apply or download extra plugins which is great. However this forces me to add the buildScan Terms of Service acceptance in my build.gradle file.

like this:

buildScan {
    termsOfServiceUrl = 'https://gradle.com/terms-of-service'
    termsOfServiceAgree = 'yes'
}

When I subsequently run gradle build without the --scan option I get the following error message:

> Could not find method buildScan() for arguments…

I don’t want to have to modify the build.gradle file every time I want/dont want a scan. I don’t want to apply the plugin explicitly (firewall issues) and I don’t get the chance to accept the of Terms of Service on the command line which I have also seen documented.

Can anyone tell me what I am doing wrong?

This question is formatted like a quote because it was already asked on Gradle Forums. But it's left without answer. I'm using Gradle 4.10.2 and the problem is still actual. I decided to draw more attention to this problem here.

Answer 1

Just test the existence of buildScan

if (hasProperty('buildScan')) {
    buildScan {
        termsOfServiceUrl = 'https://gradle.com/terms-of-service'
        termsOfServiceAgree = 'yes'
    }
}

You just need to add the above block of code in the buid.gradle(Project) file and the build scan will automatically published.

In the Jenkins, you will the link with results of the build scan.
