nvkleban · 2023-11-20T13:44:21Z

Describe the bug
Sometimes Kover generates error stacktrace in the start of html report file for some modules in android project. Can't reproduce it reliably.

When generating an HTML report, errors sometimes occur when reading the freemarker template from resources. The exact cause of the error has not yet been determined (relates to the Gradle isolated class loaders), but it disappears when you try to read again. In some cases, it is necessary to increase the number of repetitions, so this setting was made in Kover Gradle plugin. Fixes #510

Fixed in 0.7.6

If the problem repeats frequently again, reopen the issue.

nvkleban · 2024-04-03T15:09:33Z

@shanshin Not sure if it's the same error but on CI this one happened:

> A failure occurred while executing kotlinx.kover.gradle.plugin.tools.kover.HtmlReportAction
> Failed to generate file: /builds/[removed]/build/reports/kover/html/ns-2/index_SORT_BY_BLOCK.html. zip file closed

Similar to experienced in 436

kover = "0.7.6"

shanshin · 2024-04-03T16:25:59Z

Yes, it's the same error, but in the coming 0.8.0 it shouldn't appear anymore.
