> h2. WildFly inter-war dependency problem when module is optional by present
> This project is provide a simple illustration of how an inter-war dependency can cause a war deployment to fail when the war it has
> declared an a dependency through jboss-deployment-structure.xml is redeployed and all the dependent modules are `optional="true"`
> {code:xml}
> <?xml version="1.0" encoding="UTF-8"?>
> <jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.1">
> <deployment>
> <dependencies>
> <module name="deployment.app1.war" optional="true"/>
> <module name="deployment.app3.war" optional="true"/>
> </dependencies>
> </deployment>
> </jboss-deployment-structure>
> {code}
> If you set optional to {{false}} or leave it out completely, then deployment happen correctly no matter the order.

> This seem to only happen under the following conditions:
> # At least three WARs are deployed in the same container.
> # App 2 has at least one Persistence Unit
> # App 2 depends on the App 1 and App 3 deployments (via jboss-deployment-structure.xml)
> # Both dependencies are marked `optional`
> # With server down, deploy all applications
> # Start server
> # Redeploy all applications with server running
> # See App 2 fails. It becomes unavailable.
> This can also be triggers using the deployment triggers:
> This seems to work fine:
> {{$ touch app1.war.dodeploy app2.war.dodeploy app3.war.dodeploy}}
> This seems to result in App 2 failing to deploy.
> {{$ touch app2.war.dodeploy app3.war.dodeploy app1.war.dodeploy}}
> h3. Building these sample applications
> The gradle build expects to find a property named `serverHome` used in the deploy task. This should point to the directory
> of your WildFly install. If you are familiar with Gradle, then setting up this property will be easy.
> Executing: `gradle clean deploy` from the root project will deploy all wars
> h3. Environment
> - **OS**: Windows or MacOSX
> - **Java**: 1.8+
> - **Server**: WildFly 10.1
