New Licensing File: What if I build from a service account?

[Joe]

We use a Telerik via NuGet packages.  All of our developers have followed Telerik's instructions to build by putting our license files in our personal folders here.

%appdata%/telerik 

This all works just fine.

However our nightly build is performed by a service account.  Where do I put the telerik-license.txt file for that?  I do not want to add it to the project.   

Is there some global folder -- available to ALL users -- that the Telerik build process can copy it from?  Something not  local to the current user like %appdata%?

Hello Joe,

The Telerik licensing mechanism searches for a license also in the environment variables of the machine. In your scenario, you can take advantage of this and add variable named TELERIK_LICENSE as mentioned here.

Hi Martin,

I must be doing something wrong.   I have tried this approach and it does not work for me.  I get the following error messages every time I try to build using the environment variable approach

Here is what I did

1. I created a system level environment variable named TELERIK_LICENSE.   
2. I opened up in NotePad my existing license file (the one that works when I build in a local account), copied all of its text to the  clipboard and then pasted it in as the value of environment variable.
3. I made sure to shut-down and then restart Visual Studio
4. I cleaned my build and re-ran it.

I thought maybe I had copy-pasted wrong I so I re-downloaded the license file and did it again.  Same error.

Then I thought, maybe I should make the environment variable hold the path to the file or the path to the folder that contains the file.  So I tried that.  It did not help

Finally I deleted the environment variable and now I can build locally again (because it's now picking up the file in %appdata%/telerik)  but my problem remains.

In this case you are probably hitting the environment variable size limit on the used system, which probably clips the license key text. If you use Azure DevOps the limit is 4096 characters. 

If that is the case then you can use AzDO Secure File if you are using Azure DevOps or a similar feature in the CI system you are using. You can find an example with a YAML pipeline that uses secure files here.
