test-interactive.ps1

<#
.SYNOPSIS
  Interactive smoke test for java-service-archetype.

.DESCRIPTION
  Installs the archetype to the local Maven repo, then runs mvn archetype:generate
  in interactive mode by redirecting answers from a temp file into stdin.
  The generated project is written to a temp directory and removed on exit.

.PARAMETER Verify
  Also run `mvn verify -f parent/pom.xml` on the generated project (slow).

.EXAMPLE
  .\test-interactive.ps1
  .\test-interactive.ps1 -Verify

param([switch]$Verify)

$ErrorActionPreference = 'Stop'

# Run native commands (Maven, the JVM) through this helper. They write warnings
# and progress to stderr; under $ErrorActionPreference='Stop', PowerShell turns
# that stderr into a TERMINATING error the moment the caller redirects streams
# (e.g. `.\test-interactive.ps1 *> run.log`). 'SilentlyContinue' makes the native
# stderr non-fatal AND keeps it out of a redirected log, while the real Maven
# errors (written to stdout) and the exit-code gate below still surface failures.
