Symptoms
- I have added a certificate to a truststore but I am still getting
sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException
Diagnostic/Treatment
- Pre-condition: How to install a new SSL certificate guide.
Check Jenkins JVM can reach out to a Server via SSL
From the Script Console ($JENKINS_URL/script):
def url = "$serverUrl"
def connection = new URL(url).openConnection() as HttpURLConnection
connection.with {
println "ResponseCode: ${responseCode}"
println "Body: ${inputStream.text}"
}
A more extended script is here: checkSSLConnection.
Validate the truststore outside Jenkins
To test the connection with a plain “java command” run jrunscript -Djavax.net.ssl.trustStore=<JENKINS_TRUSTSTORE_FILE> -Djavax.net.ssl.trustStorePassword=<JENKINS_TRUSTSTORE_PASS> -e "println(new java.net.URL(\"<URL>\").openConnection().getResponseCode())"
Note:
- Do not forget to include all quotes (").
- If everything is fine the expected response is
200
In case you get a different result that expect response (200).
A - Firstly, verify your certificate is included in the <JENKINS_TRUSTSTORE_FILE> by:
keytool -list -v -keystore cacerts -alias <YOUR_ALIAS_HERE>
B -In case the javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: No name matching <SERVER_HOSTNAME> found. Check that the “CN” (Common Name) attribute of the “Owner” entry matches with the <SERVER_HOSTNAME> used by CJE or CJOC (also check the “SubjectAlternativeName” section for Multi hostname certificates)
keytool -printcert -file path/to/<YOUR_CA_FILE>.pem
Example:
> jrunscript -Djavax.net.ssl.trustStore=./cacerts-with-jenkins.example.com.jks -Djavax.net.ssl.trustStorePassword=changeit -e "println(new java.net.URL(\"https://jenkins.example.com\").openConnection().getResponseCode())"
java.lang.RuntimeException: javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: No name matching "https://jenkins.example.com found

Then checking the hostname, we realized that differs from example.com, it is CN=*.notExample.com
