NullPointerException when running scan

Ramy_Abdel-Azim · October 17, 2019, 3:33pm

Must-share information (formatted with Markdown):

which versions are you using (SonarQube, Scanner, Plugin, and any relevant extension)
Scanner v 4.0
what are you trying to achieve
scan my local repo
what have you tried so far to achieve this
I’ve run the following command:

sonar-scanner \
  -Dsonar.projectKey=lofocats_2 \
  -Dsonar.sources=. \
  -Dsonar.host.url=https://sonarqube01.dev.bo1.csnzoo.com \
  -Dsonar.login=ecf51e266a90f3a68c3e5840d9a54ff61a9d626a \
  -Dsonar.scm.provider=git \
  -Dsonar.projectBaseDir=/csnzoo/ra222c/lofo/lofocats_api-master

here is my stack trace:

Could you please let us know what is the version of SonarQube and also the version of the SCM Git plugin that is installed?

Hello
I have the same issue.

I create a new dotnet project:

mkdir TESTSONARSCANNER
cd TESTSONARSCANNER
dotnet new web
dotnet new sln
dotnet sln TESTSONARSCANNER.sln add TESTSONARSCANNER.csproj

Run the analysis:

dotnet sonarscanner begin /k:"testcsharp"
dotnet build 
dotnet sonarscanner end

Everything is working as expected:

This can be because you don’t have a commit yet. If you run “git commit”, then there will be a commit id/revision id created. After which it should work.

dmeneses · May 20, 2020, 6:16pm

Thanks for the details.
The scanner fails if it can’t find a HEAD reference when running a scan with git.
I created a ticket so that we can fix the problem: https://jira.sonarsource.com/browse/SONAR-13452

Workaround is to make sure there is a HEAD reference. In your case, you need to commit something before running the scanner.
Alternatively, if there is no HEAD, just specify -Dsonar.scm.disabled=true.
