How to release SCM-Manager v2 core

To release a new version of SCM-Manager v2 you have to do the following steps (replace placeholders <version> accordingly, eg. with 2.1.0):

Check out default branch

Make sure you have no changes you want to keep!

git fetch && git checkout -f origin/develop && git clean -fd && git checkout -B develop

Merge support branch

Check whether there is an integration branch for the previous release or bugfixes not merged into the develop branch. Merge them now.

git merge origin/support/<support branch>

Update Changelog

The changelog must be updated to reflect the changes for the new release. All unreleased changes are stored in the gradle/changelog directory. The changelog can be updated with the updateChangelog gradle task.

./gradlew :updateChangelog --release=<version>

Now we should manually check if the changelog looks good.

git diff CHANGELOG.md

If everything looks fine, we can remove the changelog directory.

rm -rf gradle/changelog

Create release branch

git checkout -b release/<version>

Commit version changes

git add CHANGELOG.md gradle/changelog
git commit -m "Adjust changelog for release <version>"

Push release branch

git push origin release/<version>

Wait for Jenkins build

Jenkins will

• update gradle.properties and package.json
• merge with master branch
• build and deploy everything
• set the new development version for the develop branch
• delete the release branch

Make a party

How to release SCM-Manager v2 plugins

To release a new version of a Plugin for SCM-Manager v2 you have to do the following steps (replace placeholder <version> accordingly, eg. with 2.1.0):

Attention: Migrate plugin to gradle

If an SCM-Manager plugin hasn't been migrated to gradle yet, this is highly recommended before release the next version. The migration from maven to gradle can easily be done using this tool.

Check out default branch

Make sure you have no changes you want to keep!

git fetch && git checkout -f origin/develop && git clean -fd && git checkout -B develop

Merge support branch

Check whether there is an integration branch for the previous release or bugfixes not merged into the develop branch. Merge them now.

git merge origin/support/<support branch>

Update SCM parent if necessary

If you need to update the parent of the plugin to a new release of SCM-Manager, change it now:

• build.gradle: scmVersion
• package.json: dependencies.ui-plugins

Plugin dependencies

Check if all plugin dependencies are proper versions and not SNAPSHOT!

Build, commit and push

./gradlew build \
&& git add yarn.lock build.gradle package.json \
&& git commit -m "Update to new version of SCM-Manager" \
&& git push origin develop

Wait for Jenkins to be green.

Update Changelog

The changelog must be updated to reflect the changes for the new release. All unreleased changes are stored in the gradle/changelog directory. The changelog can be updated with the updateChangelog gradle task.

./gradlew :updateChangelog --release=<version>

Now we should manually check if the changelog looks good.

git diff CHANGELOG.md

If everything looks fine, we can remove the changelog directory.

rm -rf gradle/changelog

Create, commit and push release branch

export VERSION=<version> \
&& git checkout -b release/$VERSION \
&& git commit -am "Prepare release of $VERSION" \
&& git push origin release/$VERSION

Wait for Jenkins build

Jenkins will

• update versions in gradle.properties and package.json
• merge with master branch
• build and deploy everything
• set the new development version for the develop branch
• delete the release branch

Attention: Creating new plugins

If you are creating a new plugin which doesn't exist in the SCM-Manager Plugin-Center yet, your plugin will not be shown after the release. First you have to create a plugin.yml in the website repository.
