JakartaEE New Infra Release Job

Following Jenkins job allows to release project component from any branch of specific GitHub repository. Features:

  • automatic version numbers generation
  • existing version overwrite
  • dry run (without GitHub repository modification and OSS nexus upload)

Job setup must also follow this guide

Job parameters

This project is parameterized: checked

Name Type Default Description
RELEASE_VERSION String Version to release. Default value is from POM snapshot.
NEXT_VERSION String Next snapshot version to set (e.g. 1.2.3-SNAPSHOT). Default value is RELEASE_VERSION with last component incremented by 1.
BRANCH String master Branch to release. Default value is master.
DRY_RUN Boolean false Do not publish artifacts to OSSRH and code changes to GitHub.
OVERWRITE Boolean false Overwrite existing version in git and OSSRH staging repositories.

Shell script

Job Environment

Job is being executed by bash. Specific settings for Java build tools in new Jenkins environment:

#!/bin/bash -ex

TOOLS_PREFIX='/opt/tools'
JAVA_PREFIX="${TOOLS_PREFIX}/java/openjdk"
MVN_HOME="${TOOLS_PREFIX}/apache-maven/latest"
JAVA_HOME="${JAVA_PREFIX}/jdk-11/latest"
PATH="${MVN_HOME}/bin:${JAVA_HOME}/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

Input Parameters Processing

RELEASE_VERSION and NEXT_VERSION values can be empty. Following code replaces empty values with proper values:

  • RELEASE_VERSION: version number from current snapshot version string
  • NEXT_VERSION: RELEASE_VERSION with latest version component incremented by 1 and -SNAPSHOT suffix

Release tag name is also prepared.

Git and Build Environment Preparation

If OVERWRITE argument is active (true), remote release branch and tag names are deleted. If DRY_RUN argument is active (true), deploy:deploy argument won't be passed to maven. Old local release branch and tag are always deleted if exist and local release branch is initialized to store all code changes related to this release. GitHub bot name and e-mail are set in git configuration.

if [ ${DRY_RUN} = 'true' ]; then
  echo '-[ Dry run turned on ]----------------------------------------------------------'
  MVN_DEPLOY_ARGS=''
  echo '-[ Skipping GitHub branch and tag checks ]--------------------------------------'
else
  MVN_DEPLOY_ARGS='nexus-staging:deploy'
  GIT_ORIGIN=`git remote`
  echo '-[ Prepare branch ]-------------------------------------------------------------'
  if [[ -n `git branch -r | grep "${GIT_ORIGIN}/${RELEASE_VERSION}"` ]]; then
    if [ "${OVERWRITE}" = 'true' ]; then
      echo "${GIT_ORIGIN}/${RELEASE_VERSION} branch already exists, deleting"
      git push --delete ${GIT_ORIGIN} "${RELEASE_VERSION}" && true
    else
      echo "Error: ${GIT_ORIGIN}/${RELEASE_VERSION} branch already exists"
      exit 1
    fi
  fi
  echo '-[ Release tag cleanup ]--------------------------------------------------------'
  if [[ -n `git ls-remote --tags ${GIT_ORIGIN} | grep "${RELEASE_TAG}"` ]]; then
    if [ "${OVERWRITE}" = 'true' ]; then
      echo "${RELEASE_TAG} tag already exists, deleting"
      git push --delete ${GIT_ORIGIN} "${RELEASE_TAG}" && true
    else
      echo "Error: ${RELEASE_TAG} tag already exists"
      exit 1
    fi
  fi
fi

# Always delete local branch if exists
git branch --delete "${RELEASE_VERSION}" && true
git checkout -b ${RELEASE_VERSION}
# Always delete local tag if exists
git tag --delete "${RELEASE_TAG}" && true

# Setup jaxb-impl-bot account information
git config --global user.email "jaxb-impl-bot@eclipse.org"
git config --global user.name "Eclipse JAXBimpl Bot"

Workaround: GPG initialization

GPG setup is missing in Docker image and GPG keys are passed in KEYRING environment variables. Content of this variable must be processed and stored into GPG key store.

# Workaround: GPG initialization
gpg --batch --import ${KEYRING}
for fpr in $(gpg --list-keys --with-colons  | awk -F: '/fpr:/ {print $10}' | sort -u);
do
  echo -e "5\ny\n" |  gpg --batch --command-fd 0 --expert --edit-key $fpr trust;
done

Set Release Version

Project Group ID and Artifact ID values are retrieved from maven project (pom.xml). Those values are used in git commit messages and nexus deployments description. Release version is set in maven project (pom.xml). Updated project is stored in git release branch with corresponding message. ${VERSIONS_PLUGIN}:update-parent is not required to update project versions in most cases so you may remove it from both version updating maven calls. But there are exceptions like jaxb-ri or metro-jax-ws with boms where parent must be updated too.

# Project identifiers
ARTIFACT_ID=$(mvn -B ${HELP_PLUGIN}:evaluate -Dexpression=project.artifactId -Pstaging | grep -Ev '(^\[)')
GROUP_ID=$(mvn -B ${HELP_PLUGIN}:evaluate -Dexpression=project.groupId -Pstaging | grep -Ev '(^\[)')
STAGING_DESC="${GROUP_ID}:${ARTIFACT_ID}:${RELEASE_VERSION}"
STAGING_KEY=$(echo ${STAGING_DESC} | sed -e 's/\./\\\./g')
echo '-[ Set release version ]--------------------------------------------------------'
# Set release version
mvn -U -C -B -Pstaging \
    -DnewVersion="${RELEASE_VERSION}" -DparentVersion="${RELEASE_VERSION}" \
    -DprocessAllModules=true -DgenerateBackupPoms=false \
    clean ${VERSIONS_PLUGIN}:set ${VERSIONS_PLUGIN}:update-parent

echo '-[ Commit modified pom.xml files ]----------------------------------------------'
POM_FILES=`git status | grep -E 'modified:.*pom\.xml' | sed -e 's/[[:space:]][[:space:]]*modified:[[:space:]][[:space:]]*//'`
git add ${POM_FILES} && \
git commit -m "Prepare release ${GROUP_ID}:${ARTIFACT_ID}:${RELEASE_VERSION}"

Build and Deploy Artifacts

Old Nexus deployments with the same description groupId:artifactId:version are dropped. All artifacts are built and deployed to the staging repository. Code with release versions is tagged with release tag. This maven task requires specific settings.xml file with GPG setup. Profile oss-release is defined in parent POM. It contains setup for packaging sources and javadoc and specific setup for GPG signing plugin (--pinentry-mode loopback). Minimal version of parent POM is 1.0.5. Project's pom.xml must define versions for the following plugins:

  • maven-enforcer-plugin
  • maven-source-plugin
  • maven-javadoc-plugin
  • maven-gpg-plugin
echo '-[ Drop old staging repository deployments ]------------------------------------'
for staging_key in $(mvn -B nexus-staging:rc-list -Pstaging | egrep "^\[INFO\] [A-Z,a-z,-]+-[0-9]+\s+[A-Z]+\s+${STAGING_KEY}" | awk '{print $2}'); do
  echo "Repository ID: ${staging_key}"
  mvn -U -C -B -Pstaging \
      -DstagingRepositoryId="${staging_key}" \
      nexus-staging::rc-drop
done
echo '-[ Deploy artifacts to staging repository ]-------------------------------------'
mvn -U -C -B -Poss-release,staging \
    -DskipTests -Ddoclint=none \
    -DstagingDescription="${STAGING_DESC}" \
    clean package source:jar javadoc:jar gpg:sign install:install ${MVN_DEPLOY_ARGS}
echo '-[ Tag release ]----------------------------------------------------------------'
git tag "${RELEASE_TAG}" -m "Release ${GROUP_ID}:${ARTIFACT_ID}:${RELEASE_VERSION}"

Set Next Development Cycle Version

Next development cycle SNAPSHOT version is set in maven project (pom.xml). Updated project is stored in git release branch with corresponding message.

echo '-[ Set next snapshot version ]--------------------------------------------------'
mvn -U -C -B -Pstaging \
    -DnewVersion="${NEXT_VERSION}" -DparentVersion="${NEXT_VERSION}" \
    -DprocessAllModules=true -DgenerateBackupPoms=false \
    clean ${VERSIONS_PLUGIN}:set ${VERSIONS_PLUGIN}:update-parent

echo '-[ Commit modified pom.xml files ]----------------------------------------------'
POM_FILES=`git status | grep -E 'modified:.*pom\.xml' | sed -e 's/[[:space:]][[:space:]]*modified:[[:space:]][[:space:]]*//'`
git add ${POM_FILES} && \
git commit -m "Prepare next development cycle for ${NEXT_VERSION}"

NOTE: Once you're committed to the release, this release branch should be merged into master and deleted. This will move master to the next snapshot version and prepare it for future development. For example:

$ git pull -r
$ git merge origin/1.2.3-RELEASE
$ git push origin master
$ git branch -D 1.2.3-RELEASE    # deletes local branch, in case it exists
$ git push origin :1.2.3-RELEASE # deletes remote branch

Update Git Repository

If DRY_RUN argument is not active (false), release branch and tag will be pushed to GitHub.

if [ ${DRY_RUN} = 'true' ]; then
  echo '-[ Skipping GitHub update ]-----------------------------------------------------'
else
  echo '-[ Push branch and tag to GitHub ]----------------------------------------------'
  git push ${GIT_ORIGIN} "${RELEASE_VERSION}"
  git push ${GIT_ORIGIN} "${RELEASE_TAG}"
fi
