Hi,

You are trying to use a Maven archetype that does not exist.

Maven archetype can be used to scaffold your project structure.

Bonita provides a couple of archetypes for its specific extensions, like:

You may re-use one of those for your use case and remove the unwanted features (eg: use the connector archetype with groovy)

You can also use the simple archetype provided by maven and follow the tutorial to fill your pom.xml

Thank you for your reply. 
My problem is that I want to use the grrovy language instead of java, which is less accessible for me. 
I don't know how to generate the directory structure for groovy and also how to declare the first class. Maybe there are package dependencies to add in the name.xml for using groovy. all this is vague for me. I'll continue the research if you have a zip or repo of custom extension library in groovy not java.

I suggest using the connector archetype with groovy to get you started.

Hello i have try to use custom connector on this way : 

```

mvn -B archetype:generate \

-DarchetypeGroupId=org.bonitasoft.archetypes \

-DarchetypeArtifactId=bonita-connector-archetype \

-DgroupId=xyz.bindtech.extension -DartifactId=bonita-extension-bank -Dversion=1.0-SNAPSHOT \

-Dpackage=xyz.bindtech.extension -DbonitaVersion=9.0.0 -DclassName=Bank -Dlanguage=groovy -Dwrapper=true

```

 

after i delete some folders

```shell

rm -rf /DevEnvironment/bonita-extension-bank/schemas

rm -rf /DevEnvironment/bonita-extension-bank/src/assembly

rm -rf /DevEnvironment/bonita-extension-bank/src/main/resources

rm -rf /DevEnvironment/bonita-extension-bank/src/main/resources-filtered

rm -rf /DevEnvironment/bonita-extension-bank/target

```

Hi DrakunDry ,

Maybe a good way to get you started with a Groovy connector is watching the replay of this webinar where we create a custom connector step-by-step: https://www.bonitasoft.com/videos/replay-stop3-back-to-school

Hope this helps
