set -e causes the shell to exit whenever a pipeline, list, or compound command exits with non-zero status;
set -u causes the shell to exit whenever it attempts to expand a parameter which isn't defined.
set -o pipefail If set, the return value of a pipeline is the value of the last (rightmost) command to exit with  a  non-zero  status,  or
       zero if all commands in the pipeline exit successfully.  This option is disabled by default.

Environment variables
The git plugin sets several environment variables you can use in your scripts:

GIT_COMMIT - SHA of the current
GIT_BRANCH - Name of the remote repository (defaults to origin), followed by name of the branch currently being used, e.g. "origin/master" or "origin/foo"
GIT_LOCAL_BRANCH - Name of the branch on Jenkins. When the "checkout to specific local branch" behavior is configured, the variable is published.  If the behavior is configured as null or **, the property will contain the resulting local branch name sans the remote name. 
GIT_PREVIOUS_COMMIT - SHA of the previous built commit from the same branch (not set on first build on a branch)
GIT_PREVIOUS_SUCCESSFUL_COMMIT - SHA of the previous successfully built commit from the same branch (not set on first build on a branch)
GIT_URL - Repository remote URL
GIT_URL_N - Repository remote URLs when there are more than 1 remotes, e.g. GIT_URL_1, GIT_URL_2
