I've created a domain from pom.xml:

<plugin>
                <groupId>org.glassfish.maven.plugin</groupId>
                <artifactId>maven-glassfish-plugin</artifactId>
                <version>2.1</version>
                <configuration>
                    <glassfishDirectory>${glassfish.home}</glassfishDirectory>
                    <user>${domain.username}</user>

                    <domain>

                        <iiopPort>3700</iiopPort>
                        <jmsPort>7676</jmsPort>
                        <reuse>false</reuse>
                        <jvmOptions>

                        </jvmOptions>
                        <properties>
                            <property>
                                <name>server.log-service.file</name>
                                <value>${domain.log.dir}/server.log</value>
                            </property>
                        </properties>
                        <auth>
                            <realm>
                                <name>testRealm</name>
                                <className>com.sun.enterprise.security.auth.realm.file.FileRealm</className>
                                <properties>
                                    <property>
                                        <name>jaas-context</name>
                                        <value>test</value>
                                    </property>
                                    <property>
                                        <name>file</name>
                                        <value>${project.build.outputDirectory}/keyfile</value>
                                    </property>
                                </properties>
                            </realm>
                        </auth>
                        <resources/>
                    </domain>
                    <components>
                        <component>
                            <name>${project.artifactId}</name>
                            <artifact>${project.build.directory}/artifacts/${project.build.finalName}.war</artifact>
                        </component>
                    </components>
                </configuration>
            </plugin>

the command: mvn glassfish:create-domain succeeds.

When I try to run: mvn glassfish:start-domain, I see the follwing text in my console:

[INFO] addJvmOptions: OUT Property -Djava.security.auth.login.config=C:ProjectsxyzservermodulesFrontServertargettest-classes/login.conf

This is a path which is missing all the slash'es in the path.
