There are a number of steps to releasing jetty. It is not just limited to running a couple of maven commands and then moving onto bigger and better things. There are a number of process related issues once the fun maven bits have been completed.
This release script is for jetty-9 (to release jetty-7 or jetty-8 see older documentation).
Pick your version identification strings.
These follow a strict format and will be used when prompted during step 6 below.
Release Version : 9.0.0.v20130322 (v[year][month][day]) Next Development Version : 9.0.1-SNAPSHOT Tag Name : jetty-9.9.0.v20130322
We use the 'release-9' branch to avoid problems with other developers actively working on the master branch.
// Get all of the remotes $ git pull origin // Create a local tracking branch (if you haven't already) $ git branch --track release-9 refs/remotes/origin/release-9 // Check out your local tracking branch. $ git checkout release-9 // Merge from master into the branch (this becomes your point in time // from master that you will be releasing from) $ git merge --no-ff master
Update the VERSION.txt with changes from the git logs, this populates the resolves issues since the last release.
$ mvn -N -Pupdate-version
Edit the VERSION.txt file to set the 'Release Version' at the top alongside the Date of this release.
$ vi VERSION.txt
Make sure everything is commit'd and pushed to git.eclipse.org
$ git commit -m "Updating VERSION.txt top section" VERSION.txt $ git push origin release-9
NOTE: This step updates the <version> elements in the
pom.xml files, does a test build with these new versions, and then
commits the pom.xml changes to your local git repo. The
eclipse-release profile is required on the prepare in
order to bring in the jetty aggregates as that profile defines a
module which is ignored otherwise.
$ mvn release:prepare -DreleaseVersion=9.0.0.v20130322 \ -DdevelopmentVersion=9.0.1-SNAPSHOT \ -Dtag=jetty-9.0.0.v20130322 \ -Peclipse-release
Perform the Release
NOTE: This step performs the release and deploys it to a oss.sonatype.org staging repository.
$ mvn release:perform
Set up files for next development versions.
VERSION.txt for 'Next Development
Version' at the top. Do not date this line.
Make sure everything is commit'd and pushed to git.eclipse.org
$ vi VERSION.txt $ git commit -m "Updating VERSION.txt top section" VERSION.txt $ git push origin release-9
Close the staging repository on oss.sonatype.org
Announce stage to the mailing list for testing.
Once the staged repository has been approved by the rest of the committers.
Release the staging repository to maven central on oss.sonatype.org
Merge back the changes in release-9 to master
$ git checkout master $ git merge --no-ff release-9 $ git push origin master
Define the jetty.eclipse.website server entry in your .m2/settings.xml file. You'll need to have access to the dev.eclipse.org machine to perform these actions. If you don't know if you have access to this then you probably don't and will need to ask a project leader for help.
To build and deploy the aggregate javadoc and jxr bits:
$ cd target/checkout $ mvn -Paggregate-site javadoc:aggregate jxr:jxr $ mvn -N site:deploy
This will generate the aggregate docs and deploy them to the
directory on download.eclipse.org.
Since we also provide alternative locations to download jetty distributions we need to copy these into place. There are a couple of scripts that will take care of this although they need to be localized to your particular execution environment and you need to have authorization to put stuff where it needs to go. These scripts are located at: http://git.eclipse.org/c/jetty/org.eclipse.jetty.admin.git/tree/release-scripts.
To localize the scripts to your environment:
ensure you have "curl" installed
edit the scripts and replace all ssh login lines with your own login id
Once these are setup you can deploy a release to eclipse and codehaus with the following incantation:
$ ./promote-to-eclipse.sh 9.0.0.v20130322 ( for 7 and 8 releases remember the codehaus part) $ ./promote-to-codehaus.sh 8.1.0.v20130322 8.1.0
Each of these scripts will download all of the relevant files from maven central and then copy them into the correct location on eclipse and codehaus infrastructure. On the eclipse side of it they will also adjust the xref and javadoc documentation links if they remain broken as well as regenerate all of the html files on the eclipse download site.
Since we are not allowed to have symbolic links on the download site we have to log into the machine manually and remove the previous stable directory and update it with a new release. Maintaining the conventions we use on the site will allow all 'stable' links to be stable and not needed to update to the latest major Jetty build version:
$ ssh <user>@build.eclipse.org $ cd ~downloads/jetty/ $ rm -Rf stable-9 $ cp -r <version> stable-9 $ ./index.sh
This needs to be done for all Eclipse Jetty releases (regardless of version). In addition we have to work to reduce the footprint of jetty on the primary eclipse download resources so we want to move older releases to the eclipse archive site.
$ cd ~/downloads/jetty $ mv <old release> /home/data/httpd/archive.eclipse.org/jetty/ $ ./index.sh
Periodically we need to do the same for the osgi P2 repositories to keep the size of our downloads directory at a reasonable size.
Most of the jetty jars are also osgi bundles, plus we release some specific bundles that integrate jetty closely with osgi. To do this, we use a Hudson job on the eclipse infrastructure. You will need to have permission to access https://hudson.eclipse.org/hudson/view/Jetty-RT/
There are Hudson jobs that build osgi p2 repos for each of the major releases of jetty:7 (jetty-rt-bundles-7), 8 (jetty-rt-bundles-8) and 9 (jetty-rt-bundles-9). You will need to start a manual build of the job that matches the version of jetty that you are releasing. You will be prompted to supply some parameters to the build:
By default, this is ticked. Leave it ticked.
Enter the version number of the release, eg 9.2.6.v20141205
Leave this blank.
Enter the major.minor.point release number, eg 9.2.6
This is ticked by default. Leave it ticked
This is not the branch of the jetty release. Rather it refers to the branch structure of the project that drives the jetty p2 release. It will already be set correctly for the selected job, so don't change it unless you have an extremely good reason.
Once you have supplied the necessary parameters, the build job will
commence and the bundles and update site zips will generated and
automatically placed in the
, where [MAJOR.VERSION] matches the major version number of the jetty
release you are doing. These files will then be visible from
where [MAJOR.VERSION] corresponds to the major version of the jetty
release you are doing.
There are two git repositories you need to be aware of for releasing jetty-documentation. The jetty-documentation is located in our github repository and the jetty-website is located at eclipse.
Do the following steps to publish documentation for the release:
Checkout the jetty-documentation repository.
Edit the <version> of the jetty-documentation pom.xml and change it locally to be the release number, eg 9.2.6.v20141205
Build the documentation with mvn clean install
Checkout the jetty-website
Inside the documentation/ directory, make a directory named the same as the release number, eg 9.2.6.v20141205/
Copy the built
jetty-documentation/target/docbkx/html/jetty into the new
index.html file in the
documentation directory and add the newly
released documentation url. Make sure you follow the other examples
and include the
rel="nofollow" attribute on the link so
that search engines do not crawl newly created documentation,
otherwise we are subject to duplicate content penalties in SEO.
Commit the changes to the jetty-website project
There is a separate Jenkins build job that publishes documentation to http://www.eclipse.org/jetty/documentation/current triggered by a push of changed files to the jetty-documentation project. If you commit your change to the <version> number from step 2, then these builds will use the same release version number. It is preferable if you don't commit that version number change, or better yet, ensure that it is set to the next -SNAPSHOT version number for your jetty major release number.
You will need to have appropriate permissions to do this. Log on to the Eclipse portal and select My Eclipse Account, then select "Bugzilla Manager: components, targets, milestones", and follow the links to insert a new version number for the release you have just done.
