2 things :

  • Are you sure that the environment variable is visible by the account that runs the agent ? If no, set it system-wide or specify it for this account as well.
  • When you go to Project Settings -> Agent Pool -> -> , in the capabilities tab, do you see the JAVA_HOME set ? If not and point above has been verified, you can try yo reconfigure your local agent by issuing .\config.cmd remove then .\config.cmd so i might scan newest env variables and then you should be good to go.


As a last resort I rebooted the server and it was ok. It would appear the previous settings were cached or something.

Hi @mickaelcaro

Im having the same issues with sonar_scanner in Azure DevOps…
I have a reference setup to JAVA_HOME and also in Path but am always getting errors saying that Java home can not be found

Could not find ‘java’ executable in JAVA_HOME or PATH.

In your reply above you mention issuing .\config.cmd remove … what config file are you refering to ? I can not see this file in the scanner package. I have also tried stopping the agent and starting again…

Hi, the .config.cmd file is the config file of the build agent, located in the root folder of its installation path.
