Announcing WildFly Swarm 2017.5.0

WildFly Swarm 2017.5.0

To celebrate May Day, we’re going to work 8 hours today and give you the 2017.5.0 release of WildFly Swarm.

What’s New?

More YAML fixes

We’ve fixed, we hope, for the last time, loading of project-<stageName>.yml with correct precedence, plus the ability to specify the current stage(s) through either the -S command-line argument or through the -Dswarm.config.stage property.

Additionally, we should support both the previous .yml extension and the seemingly more correct .yaml extension. Unless you’re on DOS 3.1. Then you’re still limited to 8.3 naming, of course.

Still better auto-detection

We’ve attempted to improve the auto-detection of required fractions, accounting for and persistence.xml among other things.

More auto-installed JDBC drivers

We’ve enhanced the list of detected JDBC drivers that WildFly Swarm can wire up for you now, to include:

  • PrestoDB

  • MariaDB

  • Derby

  • Hive2

  • Teiid

What is WildFly Swarm?

WildFly Swarm is the decomposition and reconstitution of the popular WildFly Java Application Server in order to support just enough appserver for microservice type applications.

Each portion of the appserver is referred to as a fraction, which many times maps to a subsystem from WildFly, but also may include other discrete chunks of non-Java EE or WildFly functionality, such as Swagger, or Jolokia.
