The latest Javadocs with links to source code can be found on the Taverna Web site.
In order to generate Javadocs, as of Taverna 2.2.0 we have created a module taverna-javadocs in net.sf.taverna.t2.taverna-workbench under products in SVN. The module only contains one pom.xml file that contains instructions to generate javadocs as part of the "release" build profile. This means that this profile will be activated at time when we do a Taverna release with the normal
mvn install command, and not while we do builds during the usual development.
