Set up a embedded Payara 5 for Arquillian tests with DB2 z/OS drivers

Despite a lot of tutorials on using embedded Payara with Arquillian, I struggled a while to get the container running. Here are the steps

Code for configuring and deploying the embedded container

@Deployment public static Archive createDeployment() throws IOException {
File[] files = Maven.configureResolver().withMavenCentralRepo(false).loadPomFromFile("pom.xml").resolve("com.ibm:db2jcc4:version1234", "com.ibm:db2jcc_license_cisuz:version1234").withTransitivity().asFile();
final WebArchive war = ShrinkWrap.create(WebArchive.class, "test.war").addPackages(true, "my.org.backend").addPackages(true, "my.org.exceptions").addAsResource("persistence.xml", "META-INF/persistence.xml").addAsLibraries(files); // add all xml required for the queries 
Files.walk(Paths.get("src/main/resources/META-INF")).forEach(file - >{
if (file.toFile().isFile() && !file.getFileName().toString().equalsIgnoreCase("MANIFEST.MF") && !file.getFileName().toString().equalsIgnoreCase("persistence.xml")) {
final String fileName = file.toAbsolutePath().toString();
final int start = fileName.indexOf("META-INF");
final String resource = fileName.substring(start - 1);
war.addAsResource(file.toFile(), resource);
}
});
return war;
}

Mind to put the arquillian.xml under „src/test/resources“
