I use mvn-golang-wrapper plugin to build binary for Go project, and maven-assembly-plugin to pack that binary and some related files to a .tar.gz artifact. To make mvn-golang-wrapper work, I specify <packaging>mvn-golang</packaging> in my pom.xml.
The issue is that with <packaging>mvn-golang</packaging>, when Maven uploads the .tar.gz to the artifactory, it doesn't create nor update maven-metadata.xml there. If I remove the <packaging> tag, maven-metadata.xml gets created, but, of course, Go binary doesn't get built.
Just in case, Maven is being run on TeamCity CI.
