In old versions of Jenkins/Hudson, the -U flag is not used for the POM parsing step (although it is used for the build step) leading to inconsistencies depending on the state of your local repository.
This was fixed in Jenkins 1.461. In any case, possible workarounds are : - switch to freestyle job (no parsing involved *before* the build) - empty local repository Vincent 2012/8/7 Jeff <predato...@gmail.com> > The parent POM need not be in the path at all...if the relative path is > not specified and there is no parent POM in the immediate parent (../) > folder, maven will download it just like any other dependency.
