             Summary: Hot deployment causes cascading redeployment of dependent artfacts when using jboss-all.xml configuration files
                 Key: WFLY-10221
                 URL: https://issues.jboss.org/browse/WFLY-10221
             Project: WildFly
          Issue Type: Bug
    Affects Versions: 11.0.0.Final
            Reporter: John Doe
            Assignee: Jason Greene
            Priority: Minor


Let's assume I have 2 files _app.ear_ and _framework.ear_ deployed in WildFly 11.

_framework.ear_ needs to be deployed before _app.ear_ which is expressed by the _jboss-all.xml_ file contained in the app.ear/META-INF folder:

{code:java}
<jboss umlns="urn:jboss:1.0">
<jboss-deployment-dependencies xmlns="urn:jboss:deployment-dependencies:1.0">
     <dependency name="framework.ear" />
</jboss-deployment-dependencies>
</jboss>
{code}

Now something changes in _framework.ear_ and a redeployment of _framework.ear_ becomes necessary.

_app.ear_ does get redeployed, too, immediately after a hot deployment of _framework.ear_ has been carried out.

*Observations:* After the redeployment of _framework.ear_ a new _framework.ear.deployed_ marker gets created, but same does not hold for _app.ear.deployed_.

In fact no new _app.ear.deployed_ gets created at all (same timestamp for this file as before) despite a redeployment takes place.

Nevertheless, in the console I see a redeployment for the dependent _app.ear_ occurs.

Extending the example above, this is time consuming when you have a couple of additional dependencies cascading through.

I don't understand why this happens because _app.ear_ did not change.

My expectation is that only a redeployment of _framework.ear_ will take place. In my opinion there is no reason to redeploy _app.ear_, too.
