ERROR: Could not find a default branch to fall back on (Maven, CircleCI, Github)

SonarCloud
1

Hi I’ve looked through the archives and couldn’t find a solution to this one, doesn’t seem the other answers answered this one.

  • GitHub

  • Circle CI with Maven build

  • Tried both ./mvnw clean verify sonar:sonar and
    ./mvnw clean verify sonar:sonar -Dsonar.projectKey=*key in sonar cloud url*

  • Java

  • Error observed:
    [ERROR] Failed to execute goal org.sonarsource.scanner.maven:sonar-maven-plugin:3.9.1.2184:sonar (default-cli) on project myproject: Could not find a default branch to fall back on. -> [Help 1]

Hi,

Welcome to the community!

Could you provide the full analysis log?

You mean the build log from CircleCI? If not, where do I find this analysis log? Also if it helps, we have Sonar working find for our UI Angular codebase, and I notice that the SONAR_TOKEN we were given in the Analyze a project with CircleCI tutorial is different than what we used to setup the UI build.

Hi,

In your OP you provided a log snippet: the error message. I’m asking for that full log instead of just the error.

If you stepped through the UI wizard to set both of them up then it’s normal to have two different tokens, since (for simplicity) the UI has you create a new one for each project.

Ok thanks, well that’s the build log that may have some private data, can I give you the snippet you’re looking for?

Hi,

Please redact the log as necessary.

Hi,

Somehow your log omits the analysis command. It might be helpful to see what it is. Could you provide it, please? And already, I see this:

[INFO] Check ALM binding of project 'com.osc:oscauction'
[WARNING] Failed to check if project 'com.osc:oscauction' is bound
[INFO] Detected project binding: ERROR

It might be interesting to enable verbose logging (-Dsonar.verbose=true on the analysis command line).

How did you initially create this project? Was it via the UI wizard?

 
Ann

Sure I can add that, I’ll do that now. Yes this was created from the UI wizard.

If you need the part where the Sonar plugin starts, here it is:

Hi,

I think I saw that in the log already. I was looking for the actual analysis command. Something like

mvn sonar:sonar [args]

or perhaps

mvn sonar-maven-plugin:3.9.1.2184:sonar [args]

 
Ann

Oh. Build attached.

Also here’s a screenshot of the command running

maven sonar

Hi,

I’m not sure what’s going on, but that isn’t a verbose analysis log.

 
Ann

14

That’s the complete log from Circleci is there anything else I can give you?

15

Hi,

Either there’s a mismatch between the command you screenshotted and the log you sent me (different job) or there’s a mismatch between your screenshot and the command that actually ran.

I’m looking for a verbose log to either confirm or dismiss my theory that this is fundamentally a permissions problem. The other thing you could do is start double-checking all your permission tokens, both analysis and GitHub.

 
Ann

16

Nope it’s the log from the Screenshot. It could be a permissions issue I’ll double check. I’ve noticed reading this forum that this seems to be a generic error message, better messages would be invaluable right now.
