ERROR: Error during SonarScanner execution java.lang.ArrayIndexOutOfBoundsException: Index -1 out of bounds for length 1024 - sonarqube

Question

I am not able to figure out what is wrong with the sonar-scanner cli in my AWS CodeBuild container. It was working perfectly fine and stopped working all of sudden. I have searched for the exception and don't seem to figure out what is wrong with code. When I check the sonar project, it is not showing any analysis at all. Which means its failing locally does not event reach sonar server. I have checked this and many others but not able to figure out the problem. The Following is the error:
[Container] 2022/06/29 12:49:26 Running command echo $(sonar-scanner -Dsonar.projectKey=$sonar_project_key -Dsonar.sources=$CODEBUILD_SRC_DIR -Dsonar.host.url=$sonar_host_url -Dsonar.login=$sonar_login)

Please help me understand what I am doing wrong or if you need more information.

Answer 1

Found the problem: Sonar cli throws this error when file is too large. To be honest, the file wasn't even that large. It was a 2K line cloudformation template. But I can scan it with cfn_nag, no need of sonar.
