[1.1.3] run as runnable jar: traceback returns NullPointer

Please give a sample snippet

Sorry, I didn't found a option to add in the attachment the traceback.

But while I was codoing a sample snippet to explain better the problem, I found more clues about it.

In the Sikuli IDE I wrote the code:

import traceback

try:
    teste = 10/0
except:
    print(traceback.format_exc())

When I click on the button "Run" its work fine, returning the traceback about the division by zero. But when I use the option on "File" "Export as runnable jar" and try to execute the .jar from CMD it returns the java.lang.NullPointerException.

Obs. Another thing is my java is the 11

This is the full error:

I am sorry, but I do not support 1.1.3 anymore with such special problems like runnable jar.

In actual versions, the feature "export as runnable jar" is not supported anyways.

I am not sure, whether the feature will come back in the next time.

You have to find another solution.

Alright we tested with the last Sikuli version and it works fine. But we realise that its not the way we want the traceback, because in this case they will show the error line """"wrong"""", because after they "change" the file.

So, what is the right way to get other exceptions traceback besides the FindFailed?

ok, just tested your case with 2.0.5 on Win 11:
When run from the runnable jar, there seems to be a problem with the stack trace, since it reports the exception cause correctly, but the line reference points to some line in the traceback module.

So as mentioned: it does not work, but I have to leave you alone with that.

You have to find another solution, to pack and run your scripts.

No problem we will probably use sys.exc_info() with "except:", its not the better solution and not even the best practice, but its the better for now.

We are planning to migrate to the Sikuli using the Robot Framework, so its ok for this old code.

Thanks for now RaiMan!
