the bb file

use

inherit gitpkgv
SRCREV = "${AUTOREV}"
PV = "1.0+git${SRCPV}"
PKGV = "1.0+git${GITPKGV}"

any idea how can fix it

Comment 1 Randy MacLeod 2019-04-11 16:37:58 UTC

We can't risk changing the code that generates these long filenames in 2.7 but we want to come up with a solution for 2.8-M1. 

For now, can you work-around the issue by using shorter recipe names/ an abbreviated commit id in the recipe, etc?

As far as I know this isn't a problem for any of the recipes in oe-core, meta-oe, meta-virt, etc so I assume that people have just worked around the problem.
