We use: - Azure DevOps traditional pipeline definitions - Azure DevOps TFS for source control - Custom build agents - SonarCloud - C# is our main programming language Error: > ##[error]java.lang.OutOfMemoryError: Java heap space I’ve read different topics and different suggestions, but they are typically referring to a personally hosted SonarQube setup or .yaml based pipeline and don’t seem to work. How should I configure the pipeline to address this “Java heap space” problem? What settings to use and where to configure? How can i make sure this will continue to be working when i move to a hosted build agent from Microsoft?

Hey there. You can adjust the [`SONAR_SCANNER_JAVA_OPTS`](https://docs.sonarsource.com/sonarqube/latest/analyzing-source-code/analysis-parameters/#other-parameters) variable in your pipeline (see [Set variables in Pipelines \> Classic](https://learn.microsoft.com/en-us/azure/devops/pipelines/process/variables?view=azure-devops&tabs=classic%2Cbatch#set-variables-in-pipeline). For what it’s worth, you can also simply use an analysis parameter rather than an environment variable (`sonar.scanner.javaOpts`) A good starting value would be `-Xmx2G`. ---

Thank you! i will try this and let you know how it goes! ---

it still failed with the same error message: > ##[error]Exception in thread “HttpClient-1-SelectorManager” java.lang.OutOfMemoryError: Java heap space > > Exception in thread “HttpClient-1-SelectorManager” java.lang.OutOfMemoryError: Java heap space > > INFO: ------------------------------------------------------------------------ > > INFO: EXECUTION FAILURE > > INFO: ------------------------------------------------------------------------ > > INFO: Total time: 29:13.153s > > INFO: Final Memory: 98M/376M > > INFO: ------------------------------------------------------------------------ > > ##[error]ERROR: Error during SonarScanner execution Is there anyway i can easily check if the settings made any difference? should i perhaps do a print out before the analyse task to print out the variables? or specify some other settings? Or some verbose logging? ---

If you turn on `DEBUG` level logging (`sonar.verbose=true`), you should see a message like this at the beginning of your scanner logs. `12:24:30.017 DEBUG Scanner max available memory: 2 GB` If you see this, and still face the issue… my next suggestion is to bump the memory up again, from `-Xmx2G` to `-Xmx4G`. ---

Thanks, we set it to -Xmx16G, which seemed to have resolve our issues at the moment. Thank you! ---
