I have a JAR on the build path of a medium sized Java application and I would like to know where it’s used. At the most basic level if someone could tell me how to ‘Find References’ for a Jar that would be great.
Whilst I’m looking at dependencies it would be great to find a tool that would map all of my package / external library usages and graph them. I used to have a free plug-in for eclipse that did just that but I haven’t been able to rediscover it.
Thanks,
Gav
Take a look at Classpath Helper or UCDetector.
Keep in mind that certain kinds of references might be missed (reflection, spring xml config files, etc.).
As a long term solution, using Maven to manage your dependencies is a good idea.
Alternatively, if its just one jar file, remove it from your classpath and see what breaks 😉
