Building the wonder source code with maven
Building instructions are in the file BUILD.txt at the top level of the svn checkout.
https://wonder.svn.sourceforge.net/svnroot/wonder/trunk/Wonder/BUILD.txt
Currently (February 2009) the wonder frameworks, applications, etc, can be built for WebObjects 5.3.x or 5.4.x; the choice is made by using a "profile" which has the value of wo53 or wo54, e.g.:
mvn clean install -P wo54
This installs frameworks for WebObjects 5.4.x, some of which appear in your local repository with the wo54 qualifier:
./repository/wonder/core/ERExtensions/5.0.0-SNAPSHOT/ERExtensions-5.0.0-SNAPSHOT-wo54.jar
and most frameworks are the same for either version of WebObjects, and have nor need any qualifier.
To utilize these frameworks in a wonder supported project, one must add the correct dependency, and this will depend on which profile you want to link to. This is done by a maven "classifier", which is used to select the correct qualifier. A qualifier is part of the basic artifact coordinate system:
<major version>.<minor version>.<incremental version>-<qualifier>
For ERExtensions, this is: 5 . 0 . 0-SNAPSHOT - wo54; which selects the correct dependency for WebObjects 5.4.x. In the pom dependencies section this would be
<dependency>
<groupId>wonder.core</groupId>
<artifactId>ERExtensions</artifactId>
<version>5.0.0-SNAPSHOT</version>
<classifier>wo54</classifier>
</dependency>
See also the woapplication-archetype ( http://wiki.objectstyle.org/confluence/display/WOL/woapplication-archetype ) which can create wonder supported applications or frameworks which utilize the maven standard project layout.
