How to do releases
Release Numbers
CONGO uses version numbering of a.b.c.d[-SNAPSHOT].
- 'd' values are build-releases. Patches for bug fixes and feature inclusion should increement this value.
- 'c' When patches are completed, and a new feature set is included, we jump 'c' and reset 'd' to 0.
- 'b' Should be updated only when MAJOR functionality is altered, such as entire new modules, etc.
- 'a' Should never be changed.
- '-SNAPSHOT' - appended by the build system for 'on the fly' builds.
Philosophy
- All development is done against the v2 trunk. (in SVN: /svn.stonekeep.com/svn/congo/v2/trunk )
- "current" build numbers are in the pom.xml:
<groupId>com.stonekeep.congo</groupId>
<artifactId>congo</artifactId>
<version>2.0.1.2-SNAPSHOT</version>
<packaging>war</packaging>
* The 'current' version in the above notation should be 'above' the current release. Ala, for the above example, the most recent tag/release should be 2.0.1.1. The current version being worked on is '2.0.1.2' - that will be the 'next' release.
Generating a release via Hudson
A release should be done when patches are complete, and a build is ready to be punched out to run on a customer-facing site. The following process assumes the same versions as above - IE, 2.0.1.1 is the latest release, 2.0.1.2 is being worked on.
- Commit all changes against the trunk.
- Go to http://hudson.stonekeep.com - Hudson will do all the branching, tagging, and pom file editing :
- Click on the project 'congo-v2'
- Click on 'perform maven release'
- Click on 'specify release version'
- Release version should be 2.0.1.2
- Development version should be 2.0.1.3-SNAPSHOT
- Select Schedule Maven Release Build
- The new build will be on nimitz in /var/lib/maven/stoneport.com/releases/com/stonekeep/congo/congo/
Generating a release via Maven on the command line
Occasionally Hudson is not available or is acting wonky. Here's the steps to do a build / release on the command line. Details here make the same assumptions as above.
- Commit all changes against the trunk
- cd to your working directory (where the pom.xml file is)
- mvn release:clean
- mvn release:prepare
Answer questions that come up - in general, the defaults are fine:
[INFO] Checking dependencies and plugins for snapshots ...
What is the release version for "CONGO"? (com.stonekeep.congo:congo) 2.1.0.4: :
What is SCM release tag or label for "CONGO"? (com.stonekeep.congo:congo) congo-2.1.0.4: :
What is the new development version for "CONGO"? (com.stonekeep.congo:congo) 2.1.0.5-SNAPSHOT: :
[INFO] Transforming 'CONGO'...
- The new build will be in the 'target' subdirectory:
yacht:CONGO v2 trunk dbs$ ls -l target/congo*.war
-rw-r--r-- 1 dbs staff 24386297 Oct 17 08:49 target/congo-2.1.0.4.war
