Tiles Release Process

  Here you will find the steps to create releases for Tiles.

  Apache's existing documentation should be read

  * {{{http://www.apache.org/dev/release-publishing}Publishing Releases}}

  * {{{http://www.apache.org/dev/publishing-maven-artifacts.html}Publishing Maven Artifacts}}

  * {{{http://www.apache.org/dev/release}Releases Policy}}

Prerequisites

  To create a release you have to install:

  * {{{http://www.oracle.com/technetwork/java/javase/overview/index.html}Java 7}}. If you are using a newer
  version of Java <<change JAVA_HOME environment variable>>
  when calling Maven, so it points to an instance of Java 7;

  * {{{http://maven.apache.org/}Maven 3.0.5+}};

  * {{{http://www.gnupg.org/}GnuPG}};

  * {{{http://www.openssh.com/}OpenSSH}};

  * {{{http://www.graphviz.org/}GraphViz}};

One-time operations

  These operations need to be performed only one time.

* Create and publish your GPG key

  To create a GPG key, follow the
  {{{http://www.apache.org/dev/openpgp.html}guidelines}}.
  Include it in:

-------------------------------------
https://svn.apache.org/repos/asf/tiles/site/KEYS
-------------------------------------

  Publish your GPG key in a PGP key server, such as
  {{{http://pgp.mit.edu/} MIT Keyserver}}.

* Create and upload yout SSH key

  * Generate your SSH key (in this case we will use DSA encryption):

---------------------------------
ssh-keygen -t rsa
---------------------------------

  * Copy your public key to the server:

--------------------------------------
scp ~/.ssh/id_rsa.pub user@people.apache.org:.ssh/authorized_keys
--------------------------------------

  * Try to login:

---------------------------------
ssh user@people.apache.org
---------------------------------

  If it does not ask you a password, everything is ok.

* Modify <<<settings.xml>>>

  Your <<<settings.xml>>> must be modified to allow deployment.

  See {{{http://www.apache.org/dev/publishing-maven-artifacts.html#dev-env}Publishing Maven Artifacts – Setup your development environment}}

Repeatable operations

  These steps must be performed <<for each>> release.

* Prepare the release tag

  To prepare the release Subversion tag, check out the branch/trunk from where
  you are preparing the release and type:

-----------------------------------
mvn clean
mvn release:prepare -Dusername=YOUR_SVN_USER -Dpassword=YOUR_SVN_PASSWORD
-----------------------------------

  The plugin interactively will ask you the version to release, the Subversion
  tag to use and the next snapshot version. It is recommended to use the tag:
  <<tiles-autotag-X.X.X>>.

  See also {{{http://www.apache.org/dev/publishing-maven-artifacts.html}the recommendations of the ASF}}.

* Perform the Release

  To perform the release, i.e. creating and deploying Maven artifacts, use:

-----------------------------------
mvn release:perform
-----------------------------------

  It should compile and test everything, build and upload the artifacts and the website for the project.

  <<Troubleshooting>>: if upload of assemblies fails it can be done manually with

-----------------------------------
cd target/checkout/assembly/target/assemblies/
ssh user@people.apache.org mkdir /www/people.apache.org/builds/tiles/autotag/${version}/
scp * user@people.apache.org:/www/people.apache.org/builds/tiles/autotag/${version}/
-----------------------------------

* Close the staging repository

  Login to {{{https://repository.apache.org} Nexus repository}} using your Apache LDAP credentials.
  Click on "Staging". Then click on "tiles" in the list of repositories.

  In the panel below you should see an open repository that is linked to your username and ip.
  Right click on this repository and select "Close".
  This will close the repository from future deployments and make it available for others to view.
  If you are staging multiple releases together, skip this step until you have staged everything.

  Enter the name and version of the artifact being released in the "Description" field and then click "Close".
  This will make it easier to identify it later.

* Verify the staged artifacts

  If you click on your repository, a tree view will appear below.
  You can then browse the contents to ensure the artifacts are as you expect them.
  Pay particular attention to the existence of *.asc (signature) files.
  If the you don't like the content of the repository, right click your repository and choose "Drop".
  You can then rollback your release and repeat the process.

  Note the repository URL, you will need this in your vote email.

* Verify the uploaded assemblies

  * go to the destination directory on people.apache.org (cd /www/people.apache.org/builds/tiles/autotag/${version})

  * check the presence of the 3 distributions (bin, doc and src), and their signature files (*.asc, *.md5, *sha1).

* Release the JIRA version

  * In JIRA go to the version that you want to release and release it.

  * Create a new version, if it has not been done before.

  * Create the release notes and <<write down the link>> that it uses.

* Send announcement for the test build

  In <<developers mailing list>> send an announcement for the test build:

-----------------------------------
Subject: [ANNOUNCE] Tiles Autotag ${version} test build available

The test build of Tiles Autotag ${version} is available.


No determination as to the quality ('alpha,' 'beta,' or 'GA') of Tiles Autotag
${version} has been made, and at this time it is simply a "test build". We
welcome any comments you may have, and will take all feedback into
account if a quality vote is called for this build.

Release notes:

* ${jira.release.notes}

Distribution:

 * http://people.apache.org/builds/tiles/${version}/

Maven 2 staging repository:

 * https://repository.apache.org/content/repositories/tiles-[YOUR REPOSITORY ID]/

A vote regarding the quality of this test build will be initiated
within the next couple of days.
-----------------------------------

* Call for a vote

  A few days after the test build announcement, call for a vote in
  <<developers mailing list>>.

-----------------------------------
Subject: [VOTE] Tiles Autotag ${version} Release Quality

The Tiles Autotag ${version} test build has been available since ${testBuildDate}.

Release notes:

* ${jira.release.notes}

Distribution:

 * http://people.apache.org/builds/tiles/autotag/${version}/

Maven 2 staging repository:

 * https://repository.apache.org/content/repositories/tiles-[YOUR REPOSITORY ID]/

If you have had a chance to review the test build, please respond with
a vote on its quality:

 [ ] Leave at test build
 [ ] Alpha
 [ ] Beta
 [ ] General Availability (GA)


Everyone who has tested the build is invited to vote. Votes by PMC
members are considered binding. A vote passes if there are at least
three binding +1s and more +1s than -1s.
-----------------------------------

* Post-vote operations

  After a vote is finished, and it has been decided that is
  <<at least of alpha quality>>, there is the need of a post-vote process.

** Promote maven staged artifacts

  Once the release is deemed fit for public consumption it can be transfered to a
  production repository where it will be available to all users.

  Login to {{{https://repository.apache.org}Nexus repository}} again.
  Click on "Staging" and then on the repository with id "tiles-staging".
  Find your closed staging repository, right click on it and choose "Release".

  Next click on "Repositories", select the "Releases" repository
  and validate that your artifacts exist as you expect them.

** Publish distribution artifacts

  * Move assemblies into the Apache {{{http://www.apache.org/dev/release#when-to-archive}dist}} repository:

-------------------------------------------
svn co https://dist.apache.org/repos/dist/release/tiles/autotag tiles-autotag-dist-releases
mkdir tiles-autotag-dist-releases/v${version}
cd tiles-autotag-dist-releases/v${version}
scp user@people.apache.org:/www/people.apache.org/builds/tiles/autotag/${version}/* .
svn add .
svn ci
-------------------------------------------

** Update the site

  * Wait 24 hours to let the mirror sync to the release and then update the
  site. In particular you have to update the index and the download pages:

------------------------------------------------
https://svn.apache.org/repos/asf/tiles/site/src/site/xdoc/index.xml
https://svn.apache.org/repos/asf/tiles/site/src/site/apt/download.apt
------------------------------------------------

  Build and publish the site:

--------------------------------------
mvn clean site site:stage
mvn scm-publish:publish-scm
# check staging website at target/scmpublish-checkout/index.html
cd <tiles-site-checkout>/publish/tiles-autotag/
svn merge ^/tiles/site/staging/tiles-autotag .
svn ci
--------------------------------------

** Send announcement

  Finally, send an an announcement to the <<users>> and <<developers mailing
  list>>:

--------------------------------------
