-----------------------------------

             Summary: improve "Error during page generation" error message
                 Key: MSITE-713
                 URL: https://jira.codehaus.org/browse/MSITE-713
             Project: Maven Site Plugin
          Issue Type: Improvement
    Affects Versions: 3.3
            Reporter: Herve Boutemy


the actual error message doesn't tell which report plugin caused a failure:
{noformat}[INFO] ------------------------------------------------------------------------
[INFO] BUILD FAILURE
[INFO] ------------------------------------------------------------------------
[INFO] Total time: 3.649s
[INFO] Finished at: Thu May 29 15:48:19 CEST 2014
[INFO] Final Memory: 20M/491M
[INFO] ------------------------------------------------------------------------
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-site-plugin:3.4-SNAPSHOT:site (default-site) on project failure-it: Error during page generation: Error rendering Maven report: Cannot run changelog command : Can't load the scm provider. SCM Connection is not set. -> [Help 1]{noformat}

then people report m-site-p failed, which is wrong, and we need to guess from error message which report plugin failed

this should be enhanced with information on the report which failed
