Variable propagation support for JSR 223 Bash Engine #1984

Closed activeeon-bot closed 9 years ago

Original issue created by Mauricio Jost on 16, Jan 2015 at 10:13 AM - SCHEDULING-2220

Currently it is possible to read the variables map from bash scripts, but it is not possible to set new ones.

It is a limitation from the fact this engine forks a process and the only we can get is the exit code. A possible workaround would be to write to a file and use post script to read it back and then write the variables

Here there is an example of a job that uses a workaround. The idea is to use a post script to read a file created in bash task, a file containing all variables to be propagated.
