Oracle once updated the Root certificates in the JDK. The certificates used to validate the default engine download page is no longer valid.</p> <p>To verify the JDK you are using inspect your environment variables:</p> <ul> <li>windows: cmd &gt; <code>echo %JAVA_HOME%</code></li> <li>linuxs: bash &gt; <code>echo $JAVA_HOME</code></li> <li>or just fire <code>javac -version</code></li> </ul> <p>If it points to binaries older than 1.8.0_171 you should install the latest 1.8 JDK. Ensure that you update the JAVA_HOME variable to the newly installed JDK afterwards.</p>Reguel WermelingerFri, 15 Jun 2018 04:06:57 -0400https://answers.axonivy.com/questions/3326/how-to-fix-maven-build-plugin-failing-with-ssl-error/3327
