it looks like reporting for MPP is broken as errors are all written to one single file without appending the errors of different plattforms. E.g. if you have an error in js and one in jvm then in the end, main.xml only contains the errors from the jvm platform. Shall I open a bug or do I miss something?

Can you cross che of it was the same for 1.17.1?

yes, same same

Ok then is not a regression. Please open an issue. I'll check it asap :)

Will do

Not sure if this is the same problem, but when I run multiple detekt tasks at the same time, only one of them creates output files. Or they are all writing to the same file.
