Jira 1.0.x merge review
Confirm that all merges scheduled for the next kernel release have been merged to the 1.0.x branch. Tidy up KNL issues associated with release.
Backup Sakai Maven2 Repo /kernel
Be conservative. Back up https://source.sakaiproject.org/maven2/org/sakaiproject/kernel/ until we are sure that Maven properly pushes the new release to the repo.
cd /var/www/html/maven2/org/sakaiproject tar -czvf kernel-[YEARMONTHDAYHOURMINSEC].tgz kernel
Checkout the kernel project
Checkout a clean version of the project using SVN not git.
svn co https://source.sakaiproject.org/svn/kernel/branches/kernel-1.0.x/ 1.0.x
Avoid opening 1.0.x in Eclipse; otherwise you will pollute the projects with Eclipse metadata files that will have to be deleted before performing the release. Checkout with svn (not git)
Clean out local repo
Verify that a clean build works ok with no external dependencies. Issuing mvn -o clean install ensures that .m2 repo is populated, a requirement for the assembly plugin. If the build fails because external dependencies are missing in .m2 run mvn clean install, then delete /kernel and run mvn -o clean install again.
rm -rf ~/.m2/repository/org/sakaiproject/kernel mvn -o clean install
Note: check for Eclipse metadata files (.classpath, .project) and remove. Uncommitted versions of these files will cause mvn release:prepare to fail.
Run integration tests
Note: not sure if we are ready for this step.
See integration test set up instructions at https://source.sakaiproject.org/svn/test-harness/trunk/xdocs/README-INTEGRATION-TESTING.txt
Create tag
Issue the following release plugin goals. Perform a dry run first.
mvn release:prepare -DdryRun=true mvn release:clean release:prepare release:perform
~arwhyte: the combination of Maven 2.0.10 (or 2.1.0), Subversion 1.5.6 and maven-release-plugin 2.0-beta-9 on Mac 10.5.7 (Leopard) resulted in a svn commit failure during the release:perform phase when attempting to update the branch pom <version>. I resolved this issue by first performing a rollback and then added my username and password as arguments to the clean/prepare/perform goals. This problem occurred despite my ability to commit to our SVN SCM system normally using either my username/password or SSH private/public key.
mvn release:rollback mvn -Dusername=arwhyte@umich.edu -Dpassword=mypassword release:clean release:prepare release:perform
When prompted for new versions:
#set the released version to 1.0.THIS REVISION VERSION
#set the tag to kernel-1.0.THIS REVISION VERSION
#set the the new version to 1.0.NEXT REVISION VERSION-SNAPSHOT
Should the build fail rerun the following mvn goals to restart the build:
mvn clean install mvn release:prepare
Trunk vs Branch releases
When releasing from trunk, issue the branch goal to create a new branch. The release plugin will then branch the current trunk to branches/kernel-1.NEXT MINOR VERSION.x.
mvn release:clean (clean up release) mvn release:branch -DbranchName=kernel-1.1.x
Release from tag
If the release:perform should hang for some reason you can check out the tag do the following:
- restore maven2/org/sakaiproject/kernel from backup *.tgz
- check out tag and generate the release based on the tag:
cd 1.0.10 mvn release:perform -DconnectionUrl=scm:svn:https://source.sakaiproject.org/svn/kernel/tags/kernel-1.0.10
Check out and test tag
The release plugin will generate a tag. Check it out and make sure it works, binding it against a local working copy of Sakai.
Refresh Maven Repo with 1.0.10, 1.0.11-SNAPSHOT and 1.1-SNAPSHOT artifacts
For each new version (release, SNAPSHOT) issue the following command from the root folder:
If a release:
mvn -Prelease clean install deploy -DupdateReleaseInfo=true
if a SNAPSHOT:
mvn clean install javadoc:jar source:jar deploy
1. Check out 1.0.x branch (1.0.11-SNAPSHOT) and perform
mvn deploy
2. Check out kernel trunk (1.1-SHAPSHOT) and perform
mvn clean install javadoc:jar source:jar deploy
Maven will deploy the new artifacts to the Sakai Maven2 SNAPSHOT Repo automatically.
Confirmation
- Confirm Maven2 repo and Maven2 snapshot repo are populated with new artifacts
- Confirm repo permissions are correct
sudo chown -R apache:apache kernel
Repo cleanup
Move old /kernel backup archive to /var/www/html/tarball. Delete kernel-1.0.10.tgz.
Base pom.xml updates
Update 2.6.x and 2.6.0 branch poms to bind to kernel-1.0.10. File a Jira on this in order to document pom updates.
Jira Kernel project
Go to "manage versions" console at http://bugs.sakaiproject.org/jira/secure/project/ManageVersions.jspa?pid=10410
Set 1.0.10 version to released; add 1.0.10 (tentative).
Jira Release Mgmt project
Update home page and Kernel page.
Inform community with email.
links for fixforversion need to be updated to point to 1.0.10.
Example:
I've released sakai-kernel-1.0.10 and updated both the Sakai maven2 release and snapshot repositories with fresh artifacts (1.0.10, 1.0.11-SNAPSHOT; 1.1-SNAPSHOT was refreshed yesterday). Both Sakai 2.6.x and the upcoming sakai-2.6.0-rc05 will bind to 1.0.10. The issues addressed by 1.0.10 can be reviewed in Jira at http://jira.sakaiproject.org/jira/browse/KNL/fixforversion/11505 Issues addressed by earlier releases can also be reviewed in Jira at http://jira.sakaiproject.org/jira/browse/KNL?report=com.atlassian.jira.plugin.system.project:versions-panel KERNEL (K1) PROJECT INFO Jira: http://bugs.sakaiproject.org/jira/browse/KNL Confluence: http://bugs.sakaiproject.org/confluence/display/REL/Kernel+1+(K1) NOTICE: TRUNK/CONTRIB DEVELOPERS DEVELOPING AGAINST K1 Please refresh your local development environment. 1. MVN: Backup/delete the .m2/repository/org/sakaiproject/kernel of your repo 2. SVN: perform an svn update on sakai trunk code (this will pick up Sakai updates that complement the K1 updates) 3. MVN: perform a clean and install on your sakai trunk code to refresh your .m2 repo with updated kernel 1.1-SNAPSHOT artifacts. 4. Build and deploy to Tomcat. cd master mvn clean install cd .. mvn clean install sakai:deploy cheers, Anthony
