* **adapter-only** - A WildFly server with the Keycloak adapter subsystem added. This build is based on the WildFly Web Feature Pack. **keycloak-adapter-feature-pack** contains all the modules needed to run the Keycloak WildFly Adapter. Therefore, the build is _org.wildfly:wildfly-web-feature-pack_ + _org.keycloak:keycloak-adapter-feature-pack_.
* **server-only** - A WildFly server with the Keycloak adapter subsystem added. This build is based on the WildFly Full Feature Pack. **keycloak-server-feature-pack** contains all the modules needed to run the Keycloak Server without those already provided by the full WildFly Server. Therefore, the build is _org.wildfly:wildfly-feature-pack_ + _org.keycloak:keycloak-server-feature-pack_.
* **server-and-adapter** is the same thing as **server-only** except it also includes **keycloak-adapter-feature-pack**. Therefore, the build is _org.wildfly:wildfly-feature-pack_ + _org.keycloak:keycloak-server-feature-pack_ + _org.keycloak:keycloak-adapter-feature-pack_.
The build version is a server that uses the new WildFly 9 feature whereby maven artifacts are not bundled with the server. Instead, they are looked up in a repository.
