It seems to me a problem of ownership of the source.
Go to : /Users/Shared/Jenkins/Home/jobs/Jenkins4AndroidTest/workspace/XJenkins/bin/
and perform and : ls -rtl
You should see something like that :
-rw-r--r-- 1 jenkins jenkins AndroidManifest.xml
If not, give the right to jenkins to it with chown command. I will personnaly do it on all directory
sudo chown -R jenkins:jenkins /Users/Shared/Jenkins
This command will give ownership of ALL CONTENT within Jenkins directory to Jenkins User.
BE CAREFUL : This is assuming that Jenkins is launched as a service with User Jenkins. If you launch jenkins as a webapp on tomcat7 for instance, Jenkins user will be tomcat7 and you shall grand tomcat7 with ownership
