Hi Wido, I don't get this issue, I'm using openjdk version "11.0.15" 2022-04-19.
Maybe @Pearl d'Silva<mailto:pearl.dsi...@shapeblue.com> has some idea how to fix this?

[WARNING] Could not get content javax.net.ssl.SSLHandshakeException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target at sun.security.ssl.Alert.createSSLException (Alert.java:131) at sun.security.ssl.TransportContext.fatal (TransportContext.java:352) I traced this back to this part: *engine/schema/pom.xml* <execution> <id>download-checksums</id> <phase>validate</phase> <goals> <goal>wget</goal> </goals> <configuration> <url>https://download.cloudstack.org/systemvm/${cs.version}/md5sum.txt</url> <outputDirectory>${basedir}/dist/systemvm-templates/</outputDirectory> <skipCache>true</skipCache> <overwrite>true</overwrite> </configuration> </execution> The 'url' points to download.cloudstack.org where it wants to download a resource. https://download.cloudstack.org/systemvm/4.16/md5sum.txt I can download the file just fine via my browser, with cURL or wget, but my Java on my Ubuntu laptop seems to fail. I'm building with openjdk-11-jdk on Ubuntu 20.04 which is version: javac 11.0.14.1 It seems that my local Java is missing the certificate chain for the LetsEncrypt cert for download.cloudstack.org Anybody else seeing this?
