scmInfo is None with HTTPS GitHub remote URL

[olafurpg]

If cloning a repo on GitHub with HTTPS the remote URL is formatted like https://github.com/olafurpg/sbt-ci-release, which is not picked up by the automatic scmInfo detection in

sbt-git/src/main/scala/com/typesafe/sbt/SbtGit.scala

Lines 124 to 146 in 74e03af

	scmInfo := {
	val user = """(?:[^@\/]+@)?"""
	val domain = """([^\/]+)"""
	val gitPath = """(.*)\.git\/?"""
	val unauthenticated = raw"""(?:git|https?|ftps?)\:\/\/$domain\/$gitPath""".r
	val ssh = raw"""ssh\:\/\/$user$domain\/$gitPath""".r
	val headlessSSH = raw"""$user$domain:$gitPath""".r
	def buildScmInfo(domain: String, repo: String) = Option(
	ScmInfo(
	url(s"https://$domain/$repo"),
	s"scm:git:https://$domain/$repo.git",
	Some(s"scm:git:git@$domain:$repo.git")
	)
	)
	gitReader.value.withGit(_.remoteOrigin) match {
	case unauthenticated(domain, repo) => buildScmInfo(domain,repo)
	case ssh(domain, repo) => buildScmInfo(domain,repo)
	case headlessSSH(domain, repo) => buildScmInfo(domain,repo)
	case _ => None
	}
	}

A workaround is to add the following to buildSettings:

+    scmInfo ~= {
+      case Some(info) => Some(info)
+      case None =>
+        import scala.sys.process._
+        val identifier = """([^\/]+)"""
+        val GitHubHttps = s"https://github.com/$identifier/$identifier".r
+        try {
+          val remote = List("git", "ls-remote", "--get-url", "origin").!!.trim()
+          remote match {
+            case GitHubHttps(user, repo) =>
+              Some(
+                ScmInfo(
+                  url(s"https://github.com/$user/$repo"),
+                  s"scm:git:https://github.com/$user/$repo.git",
+                  Some(s"scm:git:[email protected]:$user/$repo.git")
+                )
+              )
+            case _ =>
+              None
+          }
+        } catch {
+          case NonFatal(_) => None
+        }
+    }

This issue was discovered while publishing a Sonatype release via GitHub Actions with the following error message

 [error] Failed to close the repository

It appears that GitHub Actions clone the repository with the HTTPS remote instead of SSH remote.
