Well, with such a big leap between versions I’d say whatever works is good :)
Being nervous about the jar hell is always wise. Going through the dependencies is probably the most straightforward option, unfortunately. You could try to reduce the number of Ignite modules you’re using - optional ones are not picked up by default and ignite-core has almost no dependencies. Or you could build your servers as regular Java applications, with a Main class instead of ignite.sh runner. Then you’ll declare the Ignite modules you need as dependencies, and with some Maven kung-fu you should be able to identify (and hopefully fix) conflicts at build-time.

I'm not at all excited by trying to sort through which jars I depend on but are already present in the ignite distribution / optional modules etc. Is there a magic reason not to worry about this? Is there a better way to approach it? Thanks, -- Chris -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
