To Reproduce
We run Dokka as part of an Azure pipeline and sometimes it fails in this way. Most of the times it works fine.
Dokka configuration
dokka = "1.7.10"
kotlin = "1.7.10"
kotlinxCoroutines = "1.6.3"
Installation
- Operating system: Linux in Azure pipeline
- Build tool: Gradle v7.5.1
- Dokka version: 1.7.10
Additional context
Are you willing to provide a PR?
No, because I don't know what causes this problem.
