Sonar default, meet "container state was: CONSTRUCTED" - maven-2

Question

Environment: hudson/sonar/maven2 in ubuntu locally with default parameters
And I got the log from hudson below, I can't figure out where is the problem.

Answer 1

I got this problem with .Net plugins for Sonar.
They needed all projects to be analyzed with JDK 6 (even non-.Net projects).
This error was raised when I tried to analyze projects with JDK 5.
Here is the URL of the .Net plugins : http://docs.codehaus.org/display/SONAR/.Net+plugin
The solution I got was to fork the compiler to use a JDK5 compiler on my projects which needed to be analyzed in JDK5 and not JDK6.
See on the .Net plugins page :
Maven and Sonar dotnet plugins need Java6 (at compile time and runtime)
What the sentence does not say is that all projects in your Sonar instance must use Java6.
A JIRA has been created : http://jira.codehaus.org/browse/SONARPLUGINS-1086 .

Answer 2

Got the hints from http://old.nabble.com/Another-%22Current-container-state-was%3A-CONSTRUCTED%22-problem-td28172925.html#a28194257
It seems the problem is inconsistency in maven plugins in my nexus repository, when I change to mirrors.ibiblio.org and clean the .m2 directory, everything goes fine.
BUT I don't know which plugins causes this problem and the log information is so wired, will be nice if some people points which plugin cause this problem and explain the reason for this error information
