JENKINS_HOME

/etc/sysconfig/jenkins
on Red Hat Linux).
JENKINS_HOME
environment variable.
JENKINS_HOME
before launching your web container, or before launching Jenkins directly
from the WAR file.
JENKINS_HOME
Java system property when launching your web container, or when launching
Jenkins directly from the WAR file.
web.xml
