Description

Maven Resolver spends a lot of time calculating the canonical path for a File, and subsequently interning the result, in order to generate an in memory lock object for the File. This can add up to 50% or more of the time in a build, especially when using maven-enforcer-plugin with the bannedDependencies rule with searchTransitive true.

Caching these lookups will reduce build times, even for well behaved plugins.
