There's a Payara Micro maven archetype available in Maven Central repository. Here's how to use it to generate a project: https://github.com/payara/ecosystem-maven/tree/master/payara-micro-maven-archetype
You just need to set version.javaee
to 8.0
, version.payara.micro
to 5.181
and also set version of the payara-micro-maven-plugin
to 1.0.0, which is the last one available in Maven Central right now.
However, the generated project is fairly simple - it only configures the payara-micro-maven-plugin and contains a simple html page. There's no other generator for Payara Micro yet. However any Java EE 8 project generator would work because you don't need any special configuration to build and run a microservice with Payara Micro. You can simply run the final WAR with Payara Micro from command line or you can generate an executable JAR. Payara Micro Maven plugin only makes it easier to do this from within a maven build but it's not required.
