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

Answer 1

Just test the existence of buildScan

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

Answer 2

This might not be a good or proper solution, but here's one workaround: use a try/catch to swallow the error, something like:

try {
    buildScan {
        termsOfServiceUrl = 'https://gradle.com/terms-of-service'
        termsOfServiceAgree = 'yes'
    }
} catch (MissingMethodException e){
   // This isn't the exception you're looking for
}
