Hi, Are you trying to download an artifact from an repository via https?
It seems, that your certificate is not valid for Java (e.g. it is an self signed certificate). Add your certificate to an keystore and pass that keystore to maven (e.g. -Djavax.net.ssl.trustStore=%M2_HOME%\conf\trust.jks in your MAVEN_OPTS) Greetings Jens -----Ursprüngliche Nachricht----- Von: wang xiao [mailto:cquptwan...@gmail.com] Gesendet: Donnerstag, 14.
