Error installing SonarQube on Azure DevOps server edition

[sat1 (Satish Ramamoorthy)]

Hi,
I am trying to integrate SonarQube into my Azure DevOps pipeline - my DevOps pipeline is installed on my an in-house windows server as opposed to the cloud. I am getting a java mismatch error while running the ‘Run Code Analysis’ step. Can you please help? Here are some details:

I know SonarQube requires Java 11 installed - I did go and install that on my server and I also added it to the path but I still get this error -

Here is what running the comman java --version on command prompt tells me -

 C:\Users\******>java --version
java 11.0.9 2020-10-20 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.9+7-LTS)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.9+7-LTS, mixed mode)

Error I get -

Must-share information (formatted with Markdown):

• which versions are you using - SonarQube
• what are you trying to achieve - integrating sonarQube with Azure DevOps pipeline
• what have you tried so far to achieve this - installed correct version of java.

Hi,

Welcome to the community!

I’m not an Azure expert (OK, I have no experience on Azure at all) but I can see from your log that analysis is picking up the wrong Java version.

You’ve already demonstrated that the default Java on the instance is Java 11. This means there’s a configuration somewhere that explicitly points the analyzer at Java 8. At a guess, there’s a JAVA_HOME variable configured somewhere. Can you see if you can find that?

 
HTH,
Ann

Satish,
I am encountering the same error. How were you able to resolve it?

Apologies - I did not respond to Ann’s note too earlier as well - I had to make sure that I had the right version of java installed.
Once I did that, I was able to add a new pipeline variable in my specific Azure DevOps build pipeline called JAVA_HOME - it just needed to point to the location where the relevant java version was installed.
