4. First try to build the app with mvn client:build and solve the problems along the way.

box% mvn client:build

https://pastebin.com/raw/N9eg5mFu

box% mvn -version
Apache Maven 3.6.3 (NON-CANONICAL_2019-11-27T20:26:29Z_root)
Maven home: /opt/maven
Java version: 1.8.0_282, vendor: Oracle Corporation, runtime: /usr/lib/jvm/java-8-openjdk/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "5.11.2-arch1-1", arch: "amd64", family: "unix"
box% which mvn   
/usr/bin/mvn

I wonder if I need to "install maven in graalvm", if that makes sense?

@JoelSjogren :
Welcome, my first issue reporter! :)
Here's the problem:

Downloading from snapshots: https://oss.sonatype.org/content/repositories/snapshots/com/gluonhq/client-maven-plugin/0.1.37-SNAPSHOT/maven-metadata.xml

It should be 0.1.38. I used 0.1.37-SNAPSHOT before because it contained a bugfix I needed but I guess it was removed, since 0.1.38 already has that bugfix.

Thanks for bringing this up. I've just pushed a commit with this change.
