jenkins build error

When I attempt to execute a build I created on Jenkins I get the following error immediately:

FATAL: hudson.scm.SCM.checkout(Lhudson/model/AbstractBuild;Lhudson/Launcher;Lhudson/FilePath;Lhudson/model/BuildListener;Ljava/io/File;)Z
java.lang.AbstractMethodError: hudson.scm.SCM.checkout(Lhudson/model/AbstractBuild;Lhudson/Launcher;Lhudson/FilePath;Lhudson/model/BuildListener;Ljava/io/File;)Z

it appears that jenkins can't connect to the git server but not sure how to correct this. I am very sure that my credentials are valid because I checked outside of jenkins and it works.
