See line: https://github.com/tomchavakis/nuget-license/blob/cd15113781151dcce71af304d9ea48508dd8937b/src/Methods.cs#L976

I am using your tool for quite some time now, works great and helps me a lot! But now I ran into a problem that when there is a download timeout (export licenses) the application crashes. It would be nice when the execption is caught and logged. Now our build fails for difficult to troubleshoot error.

try…catch for the ExportLicenseTexts function ->
catch (TimeOutException ex) { WriteOutput($“Problem during download of License url: {fileToDownload} -> {ex.Message}”); }

Can confirm it’s working as expected; both exception types are handled and logged. Log output:

HI @dbeusink , Thank you for your suggestion. Maybe I will ask you to run one more test before merging to master.
