jardiff
A tool to help visualise API differences between two different versions of
a project. Jardiff takes two jar files and outputs all the public API changes
as xml, html or plain text. Currently this is command line driven, though
we are working on an ant plugin. It requires java 1.4 to run.
<h2>Background</h2>
At OSjava, we were using a shell script to work out API differences between
our release versions. This unfortunately doesn't scale very well to larger
projects, the main reason for jardiff was to do the same in a much shorter
time (From memory it was taking minutes to get the API diff from two fairly
small jars). In it's current state, jardiff can generate the api differences
between rt.jar for java 1.4 and java 1.5 in under 20 seconds, so it should
scale to even the largest of projects.
