What the reason? Does exist workaround? Thanks.

Hey!

This sounds a lot like this problem:

HTH,

Martin, shouldn't this issue "kind=var" be fixed in STS? Why not support it?

Thanks

Hey!

The issue is with the Maven Integration for Eclipse:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=394042

So we cannot fix this ourselves directly in STS. In the meantime, I hope the workaround described at stackoverflow helps!

Cheers,
