jenkins - how to pass a value from bash to groovy? -

i'm working on jenkins install 2 script components. bash bits run first , groovy. i'd able pass value (property? other?) bash script->groovy script.

is possible? need write value property file , read in groovy?

edit: goal generate build # in bash , pass groovy set description , build # in jenkins display. appears groovy isn't available on build server i'm looking direction. experimenting 'postbuild' plugin , 'env-inject' plugin. open suggestions.

here few things consider make successful:

1. make sure you're trying accomplish 1 "execute shell" in jenkins or script.
2. export shell variable variable present in child process execute groovy script.

# foo.sh export foo=bar groovy myscript.groovy 

# myscript.groovy def env = system.getenv() string myvar=env['foo'] println myvar 

running foo.sh should produce following:

./foo.sh bar
