Hi Team,

I am facing issue while creating module, I followed the forms, my problem is same as specified below link [Building new module in Maven](https://forum.inductiveautomation.com/t/building-new-module-in-maven/12100)

Here is the plugin code

```
     <plugin>    
         <groupId>com.inductiveautomation.ignitionsdk</groupId>
            <artifactId>ignition-maven-plugin</artifactId>
            <version>1.2.0</version>   
         <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>modl</goal>
                    </goals>
                </execution>
            </executions>

            <configuration>
                <projectScopes>
                    <projectScope>
                        <name>customauth-gateway</name>
                        <scope>G</scope>
                    </projectScope>
                </projectScopes>

                <moduleId>{project.moduleId}</moduleId>
                <moduleName>{project.moduleName}</moduleName>
                <moduleDescription>Module for authorizatition </moduleDescription>
                <moduleVersion>1.2.1</moduleVersion>
                <requiredIgnitionVersion>8.1.16</requiredIgnitionVersion>
                <requiredFrameworkVersion>8</requiredFrameworkVersion>

                <hooks>
                    <hook>
                        <scope>G</scope>
                        <hookClass>{package}.GatewayHook</hookClass>
                    </hook>
                </hooks>
            </configuration>
        </plugin>

```

Added this plugin to create a module.

Getting this error  
Failed to execute goal com.inductiveautomation.ignitionsdk:ignition-maven-plugin:1.2.0:modl (default) on project customauth-gateway: Execution default of goal com.inductiveautomation.ignitionsdk:ignition-maven-plugin:1.2.0:modl failed.: NullPointerException  
Please let me know what is wrong here.

Thanks,  
Naveen Batchu.

Is there a stack trace or any additional information to go with that NullPointerException?

It looks like the actual problem is you’re trying to use an old version of Java…

```auto
