Analysis:

Difficult to Jenkins use the jdk1.5 version of the package compilation.

View the "System Setup" JDK entry for the next Jenkins already using the JDK1.7

Search on the Internet, you need to modify in the Jenkins configuration file

To modify the default JDK version
Cd/root/.jenkins/tools/hudson.tasks.maven_maveninstallation/maven/conf

First back up CP Setting.xml Setting.xml.bak

VI setting.xml File
