EnvInject plugin - Not loading variables configure in Node properties file

[Joshua Staker]

I've configured the following setting to load environment variables from a .properties file: 

1. Manage Jenkins > Manage Nodes > Node1 > Configure 
2. Under Node Properties enabled the checkbox for 'Prepare Jobs environment' 
3. In 'Properties File Path' I specify the path to the .properties file 

In the job which is running on this node, I then have a script which is just echoing the environment variable which is supposed to be loaded from the .properties file, but this is always empty. The Output shows: 

--------------------------------------------------- 
Started by user anonymous 
[EnvInject] - Loading node environment variables. 
Building remotely on Node1 (slave) in workspace C:\jenkins\workspace\EnvInject Test 
[EnvInject Test] $ powershell.exe "& 'C:\Users\ADMINI~1\AppData\Local\Temp\hudson4027871172984182957.ps1'" 


Finished: SUCCESS 
--------------------------------------------------- 

If I inject the .properties file in the Project from Build Environment or as a build step, the variable is populated, but I can't get this working by configuring it in the Node settings. Am I missing something or did I misunderstand how to use the Node setting? 

Would appreciate any help. 

Thanks, 

Josh
