null pointer when launching interpretter from the command line

[nitrocode]

Command:

java -Xmx1g -jar ..\..\Downloads\jython-standalone-2.7.0.jar -Dpython.path=Lib/ run.py -i -d -B ..\..\Downloads\burp_suite_pro.jar

Then when Burp loads I select to use a temporary project and use Burp defaults. After I click on Start Burp that's when it shows me:

An error occurred when starting a project with the selected options.

Failed to create Burp project: NullPointerException

Nothing else is outputted but this seems to be a good workaround:

1. Load Burp

   java -Xmx1g -jar ..\..\Downloads\burp_suite_pro.jar
   

2. Navigate to Extender and manually load Lib/burp_extender.py

@mwielgoszewski please could you weigh in on this?

[mwielgoszewski]

The old run.py script was for versions of Burp before the new Extender API was introduced, where you had to manually specify arguments on the command line. The latter approach, or in your terms, "workaround", is actually the preferred way to load the the jython-burp-api.

Oh that's unfortunate... I was hoping to use the run.py for automated testing.

Thanks for the update.

@nitrocode I'm trying to automate testing using Burp from the blog and was stuck with the same error as yours - Failed to create Burp project: NullPointerException on executing the command java -Xmx1g -jar ../jython.jar -Dpython.path=Lib/ run.py -i -d -B burpsuite_free_v1.7.24.jar

I'm executing the command in EC2 instance and I have no option to use the UI interface of Burp.

Can you please suggest if there is any possible workaround for the automated testing with Burp.

TIA
