Must-share information (formatted with [Markdown](https://commonmark.org/help/)):

- which versions are you using (SonarQube 9.9 Community, Scanner, “4.0.0.2929”)
- how is SonarQube deployed: docker
- what are you trying to achieve: speed up analysis

Hey guys, we have 1.1M lines of code Java project  
We want to speed up analysis (now it takes around 40 minutes per each merge request)  
I am trying to reproduce the situation locally with logs  
And I see we have a huuuge delay when I see the line

_`The Java analyzer cannot skip unchanged files in this context. A full analysis is performed for all files.`_

The line I run the task is  
`./gradlew --info sonar -Dsonar.login=sqp_6feb88adfd1ebe4d3639ba864fee3eab6037b1f5 -Dsonar.projectKey=fs -Dsonar.projectVersion='2023.5.0-SNAPSHOT' -Dsonar.newCode.referenceBranch=develop -Dsonar.log.level=INFO -Dsonar.verbose=true`

Not sure what is the issue, why can’t it skip unchanged files? Could you please tell me where should I look at?

Hey there.

Skipping unchanged files is only possible for Pull Request analysis, which is not included in Community Edition.

Hello,

I have the same problem since I upgrade to 9.9 LTS.  
I have a project that is compiled in Java 8 but I run the sonar-scanner using JDK 11.  
The analysis is successful but very slow

I have the developer version
