SnpEff error message

Question

[eb050187]

I seem to get the same error message when I try to do anything using SnpEff. It seems like other people have addressed this error by updating java, but I have tried that and think I have the most up to date version (build 1.7.0_67-b01). Any help would be greatly appreciated. Thank you.

Error Message:

what's the version of snpEff ?

[eb050187]

I think it's LGPLv3 - I just tried redownloading it today

[eb050187]

I guess it's called "snpEff_latest_core.zip"

[Devon Ryan]

I wonder if the newest version got compiled with j2se v 8, since otherwise it should be compatible with version 7, which is what you're running. Perhaps upgrading java will fix this?

[Pierre Lindenbaum]

Devon is right jdk8:

Manifest-Version: 1.0
Build-Jdk: 1.8.0
Main-Class: ca.mcgill.mcb.pcingola.snpEffect.commandLine.SnpEff

but the error message is weird. Snpeff seems to work with my jdk7

[Devon Ryan]

Thanks for confirming. Given that snpEff is explicitly supposed to work with jdk7 could someone report this to the author?

[Pierre Lindenbaum]

It doesn't mean that it's an error. I think you can compile with a modern jdk and produce an legacy code.

I'm downloaded and installed snpEff_v3_6_core.zip, it works fine, maybe you can have a try too.

For your information, my java version is 1.7.0_09-icedtea, running on 64bit OS.

May I know if you're stucked at which session, when you're building database or annotating variants file?
