in particular including Robert's commit:

57e7dbd QA: raise dependency to site 1.2.2

The problem is a bit convoluted but the dependency chain eventually points to the old dead bom 5.6.3-SNAPSHOT—the one included in the 5.6.4 release by accident.

It goes through site 1.2.1 > main 5.6.3 > bom SNAPSHOT.

Although this causes no issue at runtime for most webapps including proper dependencyManagement, the issue pops in if you check out the multisite version currently bundled in latest bundles; it won't validate & build.

rsiska was this the reason for your QA commit too bumping site version? or was there anything else?

Thanks cringele for reporting too.
