JDK maven Nexus and HTTPS

If your Nexus repository uses certificates signed by your own Root CA, chances are that a JDK doesn't trust them.

Then when you run

mvn package

you get


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


Go to your JAVA_HOME\jre\lib\security folder, where the cacerts file is located, and issue

keytool -list -v -keystore cacerts

enter "changeit" as password

this shold tell you all your trusted CAs

You should import your own CA certificate to into this keystore.


I have tried also setting:


set MAVEN_OPTS="-Dmaven.wagon.http.ssl.insecure=true -Dmaven.wagon.http.ssl.allowall=true -Dmaven.wagon.http.ssl.ignore.validity.dates=true"

but it disn't work for me.
