Announcement 1.0.0.Alpha6

What is WildFly Swarm?

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

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

What’s New in 1.0.0.Alpha6?

There’s quite a bit new stuff in this release, including support for applications that might want:

  • WildFly 10.0.0.CR5 as a base

  • ribbon.js so your single-page apps can enjoy the benefits of Ribbon-based discovery from the browser.

  • Swagger

  • Java Batch/JBeret support

  • WebServices

  • WildFly Management API (jboss-cli support)

Additionally, we’ve begun building WildFly Swarm-ified servers which can either be added as fractions into your own service, or executed standalone from artifacts that are addressable through Maven coordinates.

Also, we’ve improved our testing game, both in terms of how WildFly Swarm itself is tested, and the facilities we provide to make testing your own applications with WildFly Swarm.

These include changes to the Maven wildfly-swarm-plugin to allow

  • wildfly-swarm:start to start an application for integration-testing (used in the pre-integration-test Maven lifecycle phase)

  • wildfly-swarm:stop the opposite of :start

Important Changes

In addition to the new features and bug-fixes, there are some notable changes that you will need to undertake for your application since 1.0.0.Alpha5.

Simplified Maven artifactId

In previous versions of WildFly Swarm, all artifacts had a groupId of org.wildfly.swarm and an artifactId of wildfly-swarm-something.

We’ve simplified the artifactId to the bare name of the piece, avoiding the repetition of wildfly-swarm- as a prefix.

For instance, if you had dependencies of:


starting with 1.0.0.Alpha6, they should be simplified to:


Renamed Properties

In the name of consistency, we’ve adjusted the names of the system properties we use. Before, we had a mix of jboss.*, swarm.*, and wildfly.swarm.* properties - those now are all swarm.* properties, and, in one case, the property was made less verbose.

Public properties that have changed are:

Old New

















So if you were using any of the old properties, you’ll need to adjust accordingly.


Release notes for 1.0.0.Alpha6 are available here.

As a result of our move from GitHub issues to JIRA, some issues that are marked as part of the 1.0.0.Alpha6 release were actually part of prior releases. Apologies for any confusion that may cause when viewing the Release notes.


Per usual, we tend to hang out on in #wildfly-swarm.

We’ve moved all bug and feature-tracking to JIRA.

Documentation for this release is available.
