kernel trunk r59845 (1.1-SNAPSHOT refresh)
kernel-1.0.x r59881 (1.0.5, 1.0.6-SNAPSHOT)
Current versions
Tag: 1.0.4
Branch: 1.0.5-SNAPSHOT
Trunk 1.1-SNAPSHOT
New versions
Tag: 1.0.5
Branch: 1.0.6-SNAPSHOT
Trunk 1.1-SNAPSHOT
Testing exceptions
None. sakai.kernel.version property added to gradebook/app/standalone-app/pom.xml and sections/sections-impl/integration-support/pom.xml now binds to sakai-kernel-impl properly
Performing the release
Copy Maven2 /kernel locally
Start now as this can take some time. Folder copy will later serve as target for deploying artifacts generated during the deploy phase.
copy http://source.sakaiproject.org/maven2/org/sakaiproject/kernel to /tmp/maven2/org/sakaiproject/kernel
Backup Sakai Maven2 Repo /kernel
Create a backup copy of /kernel.
cd /var/www/html/maven2/org/sakaiproject sudo cp -R kernel kernel-[current version]
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/ kernel-1.0.x
Avoid opening it 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.
Create tag
Issue the following release plugin goals:
mvn release:prepare -DdryRun=true mvn release:clean release:prepare release:perform
When prompted for new versions:
#set the released version to 1.0.5
#set the tag to kernel-1.0.5
#set the the new version to 1.0.6-SNAPSHOT
Should the build fail rerun the following mvn goals to restart the build:
mvn clean install mvn release:prepare
to restart the build.
Note: Beware opening the kernel in Eclipse. If you do you will have to delete Eclipse metadata files (.classpath, .project) before running mvn release:prepare.
Trunk vs Branch releases
When releasing from trunk, issue the branch goal to create a new branch:
mvn release:clean (clean up release) mvn release:branch -DbranchName=kernel-1.1.x
The release plugin will then branch the current trunk to branches/kernel-1.1.x.
Edit the poms to 1.2-SNAPSHOT and commit.

Check 1.0.5 tag
The release plugin will generate a 1.0.5 tag. Check it out and make sure it works.
Refresh Maven Repo with 1.0.5, 1.0.6-SNAPSHOT and 1.1-SNAPSHOT artifacts
Each new release will require placement of corresponding kernel artifacts in the Maven2 repo.
Steps:
1. Check out 1.0.x branch (1.0.5-SNAPSHOT) and perform
mvn deploy
2. Check out kernel trunk (1.1-SHAPSHOT) and perform
mvn deploy
For each new version (tag, SNAPSHOT) issue the following command from the root folder:
If a release:
mvn -Prelease clean install deploy -DupdateReleaseInfo=true
if a SNAPSHOT
mvn deploy
Maven will populate /tmp/maven2/org/sakaiproject/kernel with updated artifacts
SNAPSHOT refreshes
When refreshing SNAPSHOT artifacts, delete the existing artifact folder and contents before running mvn deploy.
bash deletesakaiartifact.bash 1.1-SNAPSHOT /tmp/maven2/org/sakaiproject/kernel
#!/bin/sh
# Delete artifact folders prior to deploying Maven snapshot artifacts.
# This is necessary as Maven does not update it's metadata files correctly when an old artifact exists in the repo.
# bash deletesakaiartifact.bash [TARGET FOLDER NAME] (e.g., 1.1-SNAPSHOT) [LOCATION] (e.g. /tmp/maven2/org/sakaiproject/kernel)
# author=Anthony Whyte, arwhyte@umich.edu
TARGET=$1
LOCATION=$2
cd $LOCATION
echo "Removing ${TARGET} folders and content recursively from ${LOCATION}"
rm -rf `find . -type d -name ${TARGET}`
Populate Maven Repo
Tar up kernel artifacts. Copy to source.sakaiproject.org. Make sure backup of existing /kernel directory is in place. Explode tar file.
tar -cvzf kernelrepo.tgz /tmp/maven2/org/sakaiproject/kernel}} copy kernelrepo.tgz to Maven2 repo cd /var/www/maven2/org/sakaiproject tar xvzf kernelrepo.tgz
Repo permissions
Make sure repo permissions are correct
sudo chown -R apache:apache kernel
Jira Kernel project
Set 1.0.5 version to released; add 1.0.6 (tentative).
Jira Release Mgmt project
Update home page and Kernel page.
