verifyPlugin does not fails builds if verificationReportsFormats does not include PLAIN reports

[sbouchet]

What happened?

we're using pluginverification task and noticed that even the report mention errors, the task don't fail if we specify the correct failure level, if the PLAIN verificationFormat is missing
it fails only if the ALL level is used

Relevant log output or stack trace

we're currently using

pluginVerification {
        failureLevel = listOf(INVALID_PLUGIN, COMPATIBILITY_PROBLEMS, MISSING_DEPENDENCIES)
       verificationReportsFormats = listOf(MARKDOWN)

and build outuput is

...
BUILD SUCCESSFUL in 4m 46s

but as soon as i change to

pluginVerification {
        failureLevel = ALL
        verificationReportsFormats = listOf(MARKDOWN)

the same build fails with

> Task :verifyPlugin FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':verifyPlugin'.
> SCHEDULED_FOR_REMOVAL_API_USAGES: Plugin uses API marked as scheduled for removal (ApiStatus.@ScheduledForRemoval). Check Plugin Verifier report for more details.

that is the correct expected output

Steps to reproduce

check out redhat-developer/intellij-kubernetes@5eea7ff
./gradlew verifyPlugin will not fail
change build.gradle.kts to use ALL as failureLevel and it will fail
or change verificationReportFormats to 'verificationReportsFormats = listOf(MARKDOWN, PLAIN)'

found out it's because we're not using PLAIN report format.
still an issue though, but workaround is to always set PLAIN format
