---------------------------------------------------------------------
        Key: MAVEN-1461
    Summary: Poor performance of the maven reactor
       Type: Bug

     Status: Closed
   Priority: Major
 Resolution: DUPLICATE

 Original Estimate: Unknown
 Time Spent: Unknown
  Remaining: Unknown

    Project: maven
   Versions:

Environment: Windows 2000 and Solaris 9

Description:
  We have a project with about 50 subprojects, and, on average, each subproject has 20 dependencies.
   Every time we try to compile all subprojects, the reactor takes about 17 minutes to determine the order of the subprojects.
   I found that the reactor is trying to sort all the dependencies, even the third party software dependencies, and the ones that are not in the scope of the compile. Can't the dependency graph be pruned of all necessary dependencies before looking for cycles?
  I also found that there is an alternate Dependency Resolver. My tests showed that it was much faster that the default one ( about 5 minutes ) to order the dependencies using the option -Dmaven.core.dependencyresolver=org.apache.maven.jelly.tags.maven.GraphDependencyResolver
