Using Gradle Build Scans™ with Debian Gradle 4.4.x

[Sean Gilligan]

Although Build Scans™ are a proprietary add-on to Gradle, they are very
useful in a FOSS CI environment. They make it very easy to find all the
information you need to troubleshoot a failing build or find ways to
optimize build scripts.

Unfortunately, the options for agreeing to the terms-of-service in a CI
environment have been difficult to configure cleanly. (You also have to
give them your email, which I don't mind doing but some may object.)

I opened an issue with Gradle about programmatically agreeing to the TOS
and Stefan Wolf from Gradle provided an initialization script that
solves the problem:

https://github.com/gradle/gradle/issues/26316#issuecomment-1739245349

The script works with Gradle 4.4.x (FrankenGradle) through 8.x (at
least.) The nice thing about this solution is that the script lives in a
separate file and is only activated with specific command line options:

`--init-script build-scan-agree.gradle --scan`

I've tested it with bitcoinj and created two PRs that use it. They
provide examples of how to use it:

GitHub Actions: https://github.com/bitcoinj/bitcoinj/pull/3289
GitLab CI: https://github.com/bitcoinj/bitcoinj/pull/3290
