The OpenSAML 2 library uses the Maven2 build tool, which provides the following useful commands (among many others):
target/site/apidocs
directorytarget/site/unitTest
target/site/checkstyle
target/site/xref
In addition there is build profile called release
used by the OpenSAML developers to create the release distributions of the libraries. You may use this but it requires that gpg be installed as it will compute and the signatures for the distribution packages.
When building OpenSAML 2 from source it is recommended that you check out the java-opensaml2-main project, REL_2 branch. This repository contains SVN externals that causes the latest java-xmltooling, java-openws, and java-opensaml2 code to be checked out as well. It also contains a Maven project file that will build both projects. The final results will be in the java-opensaml2/target directory. Additional the project will aggregate the junit, javadoc, and jxr reports and place them in the java-opensaml2-main/target/site directory.
JDK 1.4 builds are disabled for the moment.
