But this work fine
```yaml
apiVersion: camel.apache.org/v1
kind: Integration
metadata:
name: my-integration
spec:
dependencies:
# - "mvn:org.codehaus.groovy:groovy-sql:3.0.25"
flows:
- route:
id: "test"
from:
uri: "timer://foo"
parameters:
repeatCount: 1
steps:
- script:
groovy: |
def list = [1,"App",3,4]
list.each {println it * 2}
```
### Steps to reproduce
Just run the integration on top (The only difference is the '#' in the
dependency)
### Relevant log output
```shell
```
### Camel K version
v2.7.0 (Weird i updated to 2.8.0 so i don't know why it's 2.7.0 again)
