PKIX Path Building Failed

Error Code:

javax.net.ssl.SSLHandshakeException: 
sun.security.validator.ValidatorException: 
PKIX path building failed: 
sun.security.provider.certpath.SunCertPathBuilderException: 
unable to find valid certification path to requested target.

Reason:
This error occurs when the Java environment does not trust the certificate of the server running your SonarQube instance.

Solution:
Install the server certificate to the Java key.

Steps:

1. In your browser, to the left of the URL, there is a lock icon ().

2. Click on this icon and a window will pop up. From the window, select Connection is secure.
   

3. Select the second option, i.e., Certificate is valid.
   

4. Go to the Details tab and click on Export.
   

5. Rename the certificate (e.g., codescan-certificate), then choose a location and save the certificate.
   

6. The next process is to install the certificate in the cacerts file of the jdk installed in the system using the command line.

   Command:

   keytool -import -alias {alias-name for the certificate} -keystore “{path for the cacerts file}” -file {path where we have save the certificate}

   
   Example:

   keytool -import -alias codescan-certificate -keystore "C:\Program Files\Java\jdk-11.0.9\lib\security\cacerts" -file c:/tmp/codescan-certificate.crt

When adding the certificate, password is required. The password is changeit.
