@Goooler May I kindly request your help with this issue?

Accodirding to https://github.com/pinterest/ktlint/runs/7827127989?check_suite_focus=true:

xecution failed for task ':buildSrc:generateExternalPluginSpecBuilders'.

  If the artifacts are trustworthy, you will need to update the gradle/verification-metadata.xml file by following the instructions at https://docs.gradle.org/7.4/userguide/dependency_verification.html#sec:troubleshooting-verification

I do understand that I need to add something to verification-metadata.xml, but I don't know what. I have tried to regenerate this files but this result in expanding the file from 326 lines to 2000+ lines. Any help, especially some explanation of how to resolve it myself would be appreciated.

Try ./gradlew --write-verification-metadata pgp,sha256 help, and you also need to bump the kotlin version in version catalog, I'm addressing the fix to paul-dingemans#4.

@paul-dingemans I tested this PR in Goooler#29, you can revert changes after b2a2041, and pick up 0510a0b to try again.

@Goooler Cool, it finally worked. Tnx for helping out! I am gonna try again with next Kotlin update where I can manage it without your help.
