Add http retries (like 3) before failing the build

[hfhbd]

I use sigstore to sign my artifacts that are automatically published to MavenCentral. Unfortunately, having 1 single failure during the creation of the signature fails the complete build and I need to restart the whole publishing process, including changing the version number (because of automatic publishing).

Caused by: dev.sigstore.KeylessSignerException: Failed to put entry in rekor
Caused by: org.apache.http.ConnectionClosedException: Premature end of chunk coded message body: closing chunk expected

BuildScan: https://gradle.com/s/coglbxlkoksvu

According to the logs, the rekor server closed the connection. While there is an (temporary) bug in the rekor infrastructure because I can reproduce it, the sigstore gradle plugin should retry the operation instead of failing the build directly.

Oh like try the signing again, yeah that makes sense. We do have retries in rekor I think?

I think you could organize the tasks so signing always happens before any publishing event though.

I think the most gradle compliant way to do this is in the settings file (to be compatible with project isolation), but I haven't tested this out.

rootProject.name = "my-application"
include("app", "core", "shared", "api")

val allSubprojectPaths = rootProject.children.map { it.path }

gradle.beforeProject {
    if (this != rootProject) {
        tasks.matching { it.name.contains("publish", ignoreCase = true) }.configureEach {
            val publishTask = this
            
            // this is the only weird part, where non published modules might cause some sort of failure.
            allSubprojectPaths.forEach { subPath ->
                publishTask.mustRunAfter("$subPath:sigstoreSignFiles")
            }
        }
    }
}

@hfhbd Sorry this took a while, working on the retry logic some more here, hopefully to handle this more gracefully.

Looks like this may be more about handling 409's properly than retries in normal cases.
