Estou recebendo umClassNotFoundException durante a tentativa de executar uma análise SonarQube 4.0 de Jenkins em um projeto Maven usando SonarPerfil de linguagem XML. Na análise do SonarQube, a exceção está ocorrendo durante a tentativa de executar oValidação de Esquema XML Verifica. O que pode estar errado?

Esta é a exceção do trabalho de construção do Jenkins:

Configuração:

Jenkins 1.509.2 job using Maven 2.2.1.Jenkins está funcionando sob o Tomcat 7.0.11.Versão do plugin Jenkins Sonar 2.1.Plugin XML Sonar versão 1.0.1.Análise do SonarQube 4.0 usando o perfil de linguagem XML.

Tentei iniciar a análise do Sonar a partir do trabalho do Jenkins usando o a) SonarQube runner 2.3 através da etapa de pós-compilação do Maven; e b) usando diretamente uma ação pós-construção do Sonar. Ambos dão o mesmo resultado. Observe que a análise do SonarQube ainda é concluída e posso ver os resultados no SonarQube. Eu também tentei executar o trabalho usando o Maven 3.0.3. O mesmo resultado.
