Is anyone getting "Burp requires a license key" issue?

I'm getting stuck at "This version of Burp requires a license key. To continue, please paste your license key below." Even though I'm putting the correct License key.

@abhiunix you're not the only one - I'm getting the same issue.

On the command line:

And even when I start the BurpSuite GUI from the command line:

This workaround worked for me and you may also find it interesting.

My hypothesis is that the -classpath execution option is no longer supported (check the official burp from CLI documentation). Therefore, an option to make this work is to specify all the extension related info in the user-config.json file and provide it to the official command line burp execution command using the flag --user-config-file (a default user-config.json file can be exported form a burp project and then modified as desired). The allowed execution looks something like:

java -Djava.awt.headless=true -Xmx2g -jar /opt/burpsuite/burpsuite.jar \
  --unpause-spider-and-scanner \
  --user-config-file=user-config.json \
  --project-file=project.burp -c config.xml
