h1. Requirements

# Internet connection
# You have an access to the OW2's MRM ([Nexus|http://repository.ow2.org/]), and your account can publish artifacts of the repository 'stagging'.
# Your Maven's setting file is right, containing:
#* MRM declarations,
#* Credential of the OW2's MRM to publish artifacts into the repository 'stagging'

{code}

h1. Before release

Before to start the release process, disable the continuous integration to avoid failed build because of artifacts not promote from the repository 'stagging' to the repository 'public'.
In the [Jenkins console script|http://jenkins.petalslink.com/script], execute the following script to disable all jobs:
{code}
import hudson.model.*

// For each project
for(item in Hudson.instance.items) {
println("JOB : "+item.name)
item.disabled=true
item.save()
println("\n=======\n")
}
{code}

h1. Releasing Petals ESB

To release Petals ESB, you will release, if needed, in the following order:
# Petals dev tools,
# Easycommons tools,
# Petals ESB.

h2. Releasing Petals dev tools

For each dev tools:
# prepare the release executing the command:
{code}
> mvn release:prepare
{code}
# perform the release executing the command:
{code}
> mvn release:perform
{code}

During the perform phase, Maven will ask you the PGP's pass-phrase.

Once dev tools are released, go to the [OW2's MRM to promote|http://repository.ow2.org/nexus/index.html#stagingRepositories] the released artifacts into the repository containing released artifacts:
# Select the temporary repository containing artifacts just released,
# and "close" it,
# and "release" it.

h2. Releasing EasyCommons artifacts

h3. Releasing EasyCommons artifacts for branchs 4.x.y

First, prepare the release executing the command:
{code}
> mvn release:prepare -DtagBase=https://svn.petalslink.org/svnroot/tags
{code}
Next, perform the release executing the command:
{code}
> mvn release:perform
{code}

h3. Releasing EasyCommons artifacts for trunk

Same as releasing Petals ESB artifacts of trunk.

h2. Releasing Petals ESB artifacts

> mvn release:prepare -P prepare-release-profile -DtagBase=https://svn.petalslink.org/svnroot/tags
{code}
# Next, perform the release executing the command:
{code}
> mvn release:perform -P perform-release-profile

> mvn release:prepare -Darguments="-P prepare-release-profile" -DtagBase=https://svn.petalslink.org/svnroot/tags
{code}
# Next, perform the release executing the command:
{code}
> mvn release:perform -Darguments="-P perform-release-profile"
{code}

Once Petals ESB projects are released, go to the [OW2's MRM to promote|http://repository.ow2.org/nexus/index.html#stagingRepositories] the released artifacts into the repository containing released artifacts:
# Select the temporary repository containing artifacts just released,
# and "close" it,
# and "release" it.

> mvn release:prepare -P prepare-release-profile
{code}
# perform the release executing the command:
{code}
> mvn release:perform -P perform-release-profile

{code}
> mvn release:prepare -Darguments="-P prepare-release-profile"
{code}
{warning}Caution, for *Debian package* and *ZIP distributions* artifacts, you must enter something as {{$\{petals-cli.version\}-1.1-SNAPSHOT}} as the new development version.{warning}
{warning}
Preparing release from a branch as {{.../svnroot/branches-legacy/petals-esb-enterprise-4.2.x}} requires the definition of the right tag base adding the following argument to the previous command line: {{-DtagBase=https://svn.petalslink.org/svnroot/tags}}
{warning}
{tip}
The profile {{prepare-release-profile}} is required to disable the check about SCM URL. During the release preparation, SCM URL are updated just before to tag the artifact and the SCM URL declared in the POM will not match the current SCM URL, so SCM enforcer rule must be disable.
{tip}
# perform the release executing the command:
{code}
> mvn release:perform -Darguments="-P perform-release-profile"
{code}
{tip}
The profile {{perform-release-profile}} is required to sign all deployed artifacts (required by OW2).
{tip}

Once Petals ESB projects are released, go to the [OW2's MRM to promote|http://repository.ow2.org/nexus/index.html#stagingRepositories] the released artifacts into the repository containing released artifacts:
# Select the temporary repository containing artifacts just released,
# and "close" it,
# and "release" it.

h1. After the release

h2. Acceptance & Integration tests

Update integration and acceptance tests against new SNAPSHOT versions.

h2. Enable Jenkins's jobs

Now, the continuous integration can be re-enable. In the [Jenkins console script|http://jenkins.petalslink.com/script], execute the following script to enable all jobs:
{code}
import hudson.model.*

// For each project
for(item in Hudson.instance.items) {
println("JOB : "+item.name)
item.disabled=false
item.save()
println("\n=======\n")
}
{code}

h2. Changelog

In [JIRA|http://jira.petalslink.com], release version of released projects. If needed, move unresolved issues to a next version or change its resolution state.

h2. Release the documentation

If the released component has a documentation, release the documentation 'SNAPSHOT' renaming 'SNAPSHOT' by the right version, next copying the released documentation with a new name ending with 'SNAPSHOT'

The component having a documentation to release are:
* Petals ESB container,
* Petals JBI components,
* Petals CLI,
* Petals Ant Tasks,
* Maven Petals Plugin

h2. Communication

If needed, an announcement will be done on the right channels: Twitter, News on the Petals web-site, ...

All tweets done with a personal account should be retweeted with the account '*petalslink*' to be automatically listed on the home page of the [Petals web site|http://petals.ow2.org] (see [consulting:Le Compte Twitter de Petals ESB] for more information on account '*petalslink*').
