NumberFormatException at Flake8 parser

[henriquetruta]

I'm getting an error on the Flake8 parser on this log: flake8-failure.log

It seems like the last line is causing it. When I remove it I see a lot of non-flake8 violations being reported, such as this screenshot:

Not sure if I want to support this. There are a lot of irrelevant lines in that report file. Any attempt at supporting this might make the code more complex and I'm not even sure it would be possible to support cases with this much noise.

Did you have a look at the examples here? https://github.com/tomasbjerre/violations-lib/tree/master/src/test/resources/flake8

[henriquetruta]

Yeah, I saw it. And I understand your point. I can live with the false positives. Do you think it makes sense to at least add some logic so it doesn't crash in such cases?

[tomasbjerre]

Released 1.93 now that will allow not fail. But will contain a lot of noise. If this causes other bugs in the future, it might be reverted... so still I would strongly recommend to keep the report file clean.

You are just using the library right? I did not release any plugins now.

[henriquetruta]

Just the library, yes. Thanks! Em sex, 7 de jun de 2019 às 07:45, Tomas Bjerre <notifications@github.com> escreveu:
