Thanks Gilles. I will open a jira issue to track this problem. Here is the situation we ran into. The filesystem resolver has the following patterns ivy.local.default.ivy.pattern is "[organisation]/[module]/[type]s/[artifact]-[revision].[ext] ivy.local.default.artifact.pattern is "[organisation]/[module]/[type]s/[artifact]-[revision].[ext]" and ivy.local.default.root is c:\downloads\Program Files (x86)\repo When the resolver tries to look in the local repository the (x86) was removed.
