Kanika,

Did you take a look at the [SonarQube Scanner CLI](https://docs.sonarqube.org/display/SCAN/Analyzing+with+SonarQube+Scanner#AnalyzingwithSonarQubeScanner-Troubleshooting) documentation where the Java heap space error is specifically called out?

Best regards,

Colin

Thanks for the quick response Colin.

In task, I have defined the Additional Properties as:

# Additional properties that will be passed to the scanner,

# Put one key=value per line, example:

# sonar.exclusions=\*\*/\*.bin

SONAR\_SCANNER\_OPTS=-Xmx3072m

After this also, I am getting the error!

Kanika,

The documentation mentions using SONAR\_SCANNER\_OPTS as an environment variable, not an analysis parameter, and explicitly suggests how to set it (in TFS, you can probably just add it in the Variables section of your build)

Best regards,

Colin
