Description

mvn site hangs while generating the reports (dump below). This is 100% reproducible.

This happens while contacting maven-repository.dev.java.net. The connection is opened and never closed. The connection to this external repository was done successfully several time in the same build.

Notes:

• a timeout would be useful:
  at org.apache.maven.wagon.providers.http.LightweightHttpWagon.resourceExists(LightweightHttpWagon.java:312)
  at org.apache.maven.report.projectinfo.dependencies.RepositoryUtils.dependencyExistsInRepo(RepositoryUtils.java:219)

• for some reason, the site report bypass our corporate repository (nexus). Cf MPIR-137
• workaround is to enable
  <dependencyLocationsEnabled>false</dependencyLocationsEnabled>
  <dependencyDetailsEnabled>false</dependencyDetailsEnabled>
  as done in MPIR-137
