mvn wildfly-swarm:run error

Question

I created a wildfly-swarm test project using jboss forge, but when I generate project I encounter the error:

what should I do? If anyone can help me, thank you!

Answer 1

Although you don't include your persistence.xml in your post, this error means that the default database driver wasn't started and it's referenced in your persistence.xml file used by jpa. If you're using Maven you need to include at least one of the default jdbc driver jar using compile scope, that will automatically configure the ExampleDS datasource.

Also, make sure you're using the latest ws which is 2017.5.0.
