After successfully installing a new SonarQube server, I followed the documented steps to configure the Azure DevOps integration. However when trying to register our on premise Azure DevOps instance, SonarQube throwed the following exception:
2025.02.10 11:47:30 ERROR web[13308e38-2d1a-46ae-80d9-baa54c12ffac][o.s.a.c.a.AzureDevOpsHttpClient] Unable to contact Azure DevOps server for request [https://azuredevops.server.be/tfs/defaultcollection/_apis/projects?api-version=3.0]: [PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
I found an old post online that links this error message to a problem with our SSL certificate. It seems that Java is unable to recognize the root certificate authority (CA). This could make sense as our internal Azure DevOps instance is using an SSL certificate signed by an internal root certificate.
To fix the issue, I followed the steps described in the post:
- First I exported the existing keystore to a file using the following command:
keytool -list -v -keystore "C:\Program Files\Microsoft\jdk-17.0.11.9-hotspot\lib\security\cacerts" > java_cacerts.txt
- I checked the exported file and indeed the root certificate was missing. So we need to add it to our keystore.
- I already had the root certificate available as a .cer file so I could import it immediately:
keytool -import -alias VLM_ROOT -keystore "C:\Program Files\Microsoft\jdk-17.0.11.9-hotspot\lib\security\cacerts" -file rootcert.cer
Enter keystore password:
Owner: CN=Enterprise Root CA 1, DC=server, DC=be
Issuer: CN=Enterprise Root CA 1, DC=server, DC=be
Serial number: 536c46e9d58b64a14005e8e460f5a834
Valid from: Mon Nov 08 08:08:22 CET 2021 until: Sat Nov 08 08:15:58 CET 2036
Certificate fingerprints:
Signature algorithm name: SHA256withRSA
Subject Public Key Algorithm: 2048-bit RSA key
Version: 3
- I had to confirm that I trusted this certificate:
Trust this certificate? [no]: Y
Certificate was added to keystore
After doing that I was able to create the connection between SonarQube and Azure DevOps without any other issues.
