I am trying to inject environment variables to the build process after SCM checkout. If I point to a .properties file in the workspace some variables do not get set properly while others are OK. If I copy/paste the content of the file into the "Properties Content" box in the Jenkins project configuration page then it works fine for all variables.

For example

AVARIABLE=/some/path
PATH=/opt/bin:${AVARIABLE}/bin:${PATH}
LD_LIBRARY_PATH=${AVARIABLE}/lib:${LD_LIBRARY_PATH}

where I already have some existing directories in my $PATH. If I save this in a file and point to it then I get errors :

[EnvInject] - Variables injected successfully.
[EnvInject] - Unset unresolved 'PATH' variable.
[EnvInject] - Unset unresolved 'LD_LIBRARY_PATH' variable.

But the same 3 lines work fine if I enter them directly in the "Properties Content" dialog box
