### Handling Dependencies Versions
-This module aims to be both simple and practical, as such, there are a few
recommendations to follow when contributing
-to the code on
-this particular module.
-
-The module leverages JBang's ability to [parameterize
dependencies](https://www.jbang.dev/documentation/guide/latest/dependencies.html#system-properties-and-environment-variables)
along with Antrun's
-ability to process source code on the fly and perform string substitution to
replace strings on files.
-
-During the build, the *perfectly valid* Java-based JBang script code is copied
to the `dist` directory. Then the antrun
-plugin replaces the references to parameterized dependencies. The
parameterized dependencies are in the format `${name}`.
-
-In order to minimize the problems caused by CVEs in dependencies and ensure
the correct alignment of dependencies within
-Camel, all references to dependencies should use parameterized ones. Such as:
-
-```
-//DEPS org.apache.camel:camel-bom:${camel.jbang.version}@pom
-```
-
-After being processed by antrun, during the build, the aforementioned line
would be transformed to something like (for
-a Camel 3.13.0-SNAPSHOT build):
+If needed for development and debugging purposes, dependencies can be
referenced by correctly resolving the parameterized variables on the command
line. Such as:
```
-//DEPS org.apache.camel:camel-bom:3.13.0-SNAPSHOT@pom
+jbang -Dcamel.jbang.version=3.13.0-SNAPSHOT CamelJBang.java
```
-The same applies to Camel version references, which should rely on the
`${camel.jbang.version}` parameter (such
-as when displaying help information).
-
-Despite this transformation, the code in `src/main/jbang` should be valid
nonetheless and can be executed for development
-and debugging purposes by correctly resolving the parameterized variables on
the command line. Such as:
-
-```
-jbang -Dcamel.jbang.version=3.13.0-SNAPSHOT
-Dcamel.jbang.log4j2.version=2.13.3 -Dcamel.jbang.picocli.version=4.5.0
CamelJBang.java
-```
-
-Alternatively, it is possible to just build the module and then execute the
post-processed script on the `dist` directory.
-
-```mvn clean package && ./dist/Camel```
-
### Checkstyle
Because the first line of the script requires a she-bang like line, it
violates the default checkstyle used by the
