[jboss-user] Issue with the maven plugin when using an IP address without reverse name resolution

[Dominique Broeglin]

Hello!

I encountered an issue when trying to use the jbos-as-maven-plugin to
deploy on a remote JBoss AS server. I use something akin to :

            <plugin>
                <groupId>org.jboss.as.plugins</groupId>
                <artifactId>jboss-as-maven-plugin</artifactId>
                <version>7.4.Final</version>
                <configuration>
                  <hostname>10.1.2.3</hostname>
                  <port>9999</port>
                  <username>admin</username>
                  <password>xxx</password>
                  <filename>${project.build.finalName}.ear</filename>
                  <name>backend</name>
                  <skip>false</skip>
                </configuration>
              </plugin>

And I get the following error :

Caused by: org.apache.maven.plugin.MojoExecutionException: Could not

The error is caused by the fact that the IP address I provide in the
<hostname> configuration entry does not have a reverse DNS name
associated with it. A quick workaround is to add a name for it in my
local hosts file and everything works fine. Also, when using the
jboss-cli everything works fine.

I tracked the hostname parameter in the code and I think that the
issue is in the following line of
org.jboss.as.controller.client.impl.ClientConfigurationImpl:

        return new ClientConfigurationImpl(address.getHostName(),
port, handler, null, null, createDefaultExecutor(), true);

The plugin gets an InetAddress which works fine, but when entering
this line we try to get the hostname (which does not exist) and we get
nothing back. This is then used later to construct the URI:

        configuration.setUri(new URI("remote://" +
formatPossibleIpv6Address(client.getHost()) +  ":" +
client.getPort()));

And finally we get the exception shown above.

I'm not familiar enough with the code to try an provide a patch but I
wanted at least to communicate the issue.

Hope this helps,

Dominique
