maven - pointing to a parent pom allready installed in the local cache for jenkins -

we have different environments building same snapshot version of different projects @ same time. can separate maven caches, snapshots installed @ different places , don't affect each other.

for reason though following error message when building child module:

[fatal] non-resolvable parent pom: failure find com.sample:parent-pom:pom:4.0-snapshot in http://localhost/nexus/content/groups/public/ cached in local repository, resolution not reattempted until update interval of nexus has elapsed or updates forced , 'parent.relativepath' points @ wrong local pom @ line 4, column 10 

i can't install snapshot in nexus, , can't point parent pom in file system.

the snapshot in cache, maven continue using instead of failing. ideas?

update:

this looks jenkins maven problem, if start mvn locally @ jenkins machine, same configuration , workspace, works. have no idea though how check jenkins doing.
