> In comparison with maven 2.2.1 resolving of dependencies with scope "import"
> is very slow in maven 3.
> Example results for "mvn dependency:tree" in one my project: maven 2.2.1 says
> "[INFO] Total time: 8 seconds" but 3.0.4 "[INFO] Total time: 13:02.069s".
> Resulting trees are identical.
> I profiled the code and found that maven 3 did not cache parsed pom files but
> it reads and parses one pom file every time when it find it in imported
> dependencies. So the method
> org.apache.maven.model.building.DefaultModelBuilder.importDependencyManagement()
> is called many times for one artifact. There is JProfiler result for "mvn
> dependency:tree" in attachment.
