lein run "Unsupported major.minor version 52.0" on Ubuntu 14.04

When doing lein run got unsupported major minor version error. I thought it was downloading everything by itself.
Does it require Java 8?

It looks like the latest version of Immutant might be putting in a Java 8 compiled library. You could try rolling back to [org.immutant/web "2.1.0"] to see if that helps.
yogthos commented
actually, sorry the latest release still has 2.1.0, since it looks like the problem comes from Immutant you could try using a different HTTP server, e.g: lein new luminus myapp +jetty.
rmangi commented
Have the same issue on OS X. Even after adding jetty

yogthos commented
ah right Jet is also compiled against Java 8, http-kit might be the one that works on 7
anshbansal commented
I used JDK 8 to use with this. Probably just add something in docs that JDK 8 is the requirement.
yogthos commented
It depends on the HTTP server being used, both Jet and Immutant are built against JDK8 nowadays, but I think HTTP Kit and Aleph should still work with older versions.
