According to this instruction [Gatling installation with the bundle, build tool, or package manager](https://docs.gatling.io/tutorials/oss/) i try to install Gatling to my project.  
I have a Spring Boot 3.5.3 and i added latest gatling as maven dependencies

```auto
<plugin>
<groupId>io.gatling</groupId>
<artifactId>gatling-maven-plugin</artifactId>
<version>4.19.1</version>
</plugin>

<dependencies>
<dependency>
  <groupId>io.gatling.highcharts</groupId>
  <artifactId>gatling-charts-highcharts</artifactId>
  <version>3.14.3</version>
  <scope>test</scope>
</dependency>
</dependencies>

```

When i run command ` ./mvnw clean gatling:test` the project crashed and as far as i understand thats because of version conflict Netty.

Next step i try to run gatling as independent java application.

On this page [Gatling installation with the bundle, build tool, or package manager](https://docs.gatling.io/tutorials/oss/) i downloaded two archive

1. Install Gatling using a ZIP file for build tools#

2. Use the standalone bundle#

I extract and investigate this two archive and **they absolutely the same**. What sens to create two similar link ?

The next two commands:

```auto
    cd gatling-maven-plugin-demo-java-main
    ./mvnw clean gatling:test

```

The project finished successfully and test _BasicSimulation.java_ passed.  
My custom gatling test located in my spring boot application.  
Is it possible to specify with an argument where my tests are located? Otherwise I will be forced to copy and paste test from **my-spring-boot-app/test** directory to **gatling-maven-plugin-demo-java-main**.  
Something like:

```auto
./mvnw clean gatling:test -- test-location= /path/to/my/tests/files

```

Is it possible to configure Gatling and make it as a global command line command ?  
**Correct me if i do or understand something wrong.**

Don’t share the classpath between your Java application and your Gatling tests.

> I extract and investigate this two archive and **they absolutely the same**.

They are not. You’re not display hidden folders (name starting with a dot).

> Is it possible to specify with an argument where my tests are located?

No

> Otherwise I will be forced to copy and paste test

Wrong. You can have your Gatling maven project in a subfolder of your application code repository, without mixing with your application dependencies.

Do you mean create something like this project structure ?  
I created gatling-tests package and separated pom.xml

```auto

                <version>${gatling-maven-plugin.version}</version>
                <configuration>
                    <!-- Enterprise Cloud (https://cloud.gatling.io/) configuration reference: https://docs.gatling.io/reference/integrations/build-tools/maven-plugin/#running-your-simulations-on-gatling-enterprise-cloud -->
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

```

What happens if I do **gatling-tests** as a modlue and add to the parent pom.xml

```auto
<modules>
    <module>gatling-tests</module>
</modules>

```

i assume it will be crashed .

Yes, most likely, because your application project is the parent and not a module.  
If you want a global maven project, you must make your application a module too and define all your application dependencies in the module and not the parent.
