• CI system used: Jenkins
• Languages of the repository: Java, JS, TS

During our PR analyzing, SonarCloud posts multiple warnings like these for different files:

[WARNING] Could not find key java:contentHash:MD5:<orgname>:<path to file>in the cache

Should we worry about this/tune something in order to avoid this issue?

Hey there.

Where are you getting these warnings? Can you share a screenshot / log snippet (showing what happens before/after you get these messages)

Hi @lrozenblyum,

Thank you for reporting.

No need to worry about these log messages. Currently, from your side, there is nothing you can do.
We reevaluated the log level they have, and we decided to lower them.
Here is a ticket to track progress [SONARJAVA-4528] - Jira.

All the best,

Irina

Thanks!
