# pdftract-java-publish WorkflowTemplate
#
# Publishes pdftract-java to Maven Central via Sonatype OSSRH staging.
# Triggered by milestone tag after pdftract-build-binaries completes successfully.
#
# === Maven Central Publishing Flow ===
# OSSRH requires a multi-step staging process:
#   1. Clone the Java SDK repo at the tag
#   2. Update pom.xml version to match the binary tag
#   3. Import GPG signing key from OpenBago secret
#   4. Run conformance tests (abort on failure)
#   5. Build and deploy artifacts with GPG signatures to OSSRH staging
#   6. Close and release the staging repository to Maven Central
#
# === Pre-release Handling ===
# Pre-release tags (vX.Y.Z-rc.N) publish as SNAPSHOT versions (X.Y.Z-rc.N-SNAPSHOT)
# to OSSRH snapshot repository and are NOT released to Maven Central.
#
# === Idempotency ===
# OSSRH rejects duplicate version uploads. The deploy step treats "version exists"
# as success (for snapshots) or failure (for releases — a new patch version is required).
# Re-running on the same release tag after successful publish is a no-op.
#
# === GPG Signing ===
# Maven Central requires all artifacts to be GPG-signed. The workflow imports
# the GPG private key from the ossrh-gpg-key ExternalSecret (synced from OpenBao).
# The passphrase is also stored in the same secret.
#
# === OSSRH Credentials ===
# Uses ExternalSecret `ossrh-creds-pdftract` (synced from OpenBao).
# Credentials: username + password for Sonatype OSSRH portal.
#
# === Central Sync Delay ===
# After release-to-Central, there is a ~10 minute delay before the artifact
# appears on search.maven.org due to Central's sync process.
