Hi,

I am using the workflow plugin to organize my builds on jenkins.

In my script I currently must run many "Shell Script" steps.
Most of the scripts produce some output that I should catch and use in my further steps.

Currently I handle this as following:

sh "xmlstarlet sel -N m=http://maven.apache.org/POM/4.0.0 -t -v \'/m:project/m:version\' pom.xml > .version"
def ver =  readFile '.version'

But I assume there is a better (undocumented?) way available. Does 'sh' step support more parameters?

By the way, what does 'sh' step returns? Is it shell script exit code?

Thank you in advance
