> When a slave node is configured to append/prepend to a variable (Node
> Properties->Environment Variables) that is used by EnvInject within a job,
> the injection fails. If the slave node simply sets the variable (i.e.
> doesn't reference the same variable in the act of setting) it works fine.
> Consider the following job, which has a single build step: echo $PATH
> In Build Environment->Inject, there is a single line in the properties
> content box: PATH=/opt/bin:$PATH
> That's the job. Now, the slave node, also sets the PATH variable. Let's
> first look at a working example, where the slave node sets PATH to:
> /data/goesrsw/goesr/bin Here is the output:
> [EnvInject] - Executing scripts and injecting environment variables after the
> SCM step.
> [EnvInject] - Injecting as environment variables the properties content
> PATH=/opt/bin:$PATH
> [EnvInject] - Variables injected successfully.
> [aaa] $ bash -xe /tmp/hudson5838824311735104563.sh
> + echo /opt/bin:/data/goesrsw/goesr/bin
> /opt/bin:/data/goesrsw/goesr/bin
> Notifying upstream projects of job completion
> Finished: SUCCESS
> Ok, so to demonstrate the problem, change the PATH in the slave node to:
> /data/goesrsw/goesr/bin:$PATH
> Now, here's the output:
> [EnvInject] - Executing scripts and injecting environment variables after the
> SCM step.
> [EnvInject] - Injecting as environment variables the properties content
> PATH=/opt/bin:$PATH
> [EnvInject] - Variables injected successfully.
> [EnvInject] - Unset unresolved 'PATH' variable.
> [aaa] $ bash -xe /tmp/hudson3276485997068093627.sh

> As you can see, the injection didn't work. /opt/bin is nowhere to be found.
