I've had tons of issues with the reporting in Detekt, maybe something from my earlier thread could help? https://kotlinlang.slack.com/archives/C88E12QH4/p1634170406079800?thread_ts=1634170406.079800&cid=C88E12QH4 Some issues may also be fixed in 1.19.0

Thanks @Michael Marshall, I've checked, seems my problem was that

detektTask.xmlReportFile

name was always

detekt.xml

, but when I ran

detekt<variant>

the report file was generated with

<variant>.xml

name
