[MNG-7074] Environment Variable defaulting

**[Loïc Hermann](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=loichrn)** opened **[MNG-7074](https://issues.apache.org/jira/browse/MNG-7074?redirect=false)** and commented

Hi all,

maven build in CI environment often rely on environnement variables.

If those environment variables are not defined on the developper environment the build will fail.

`For now defaulting those environment variable can only be done by defining one profile per variable which is really verbose.`

`it would be easier if we can either`

`add a default value where the variable is used:`

```

`$\{env.VARIABLE_NAME:defaultValue`}

```

or have a section to define default values in the pom:

```

   <`VARIABLE_NAME`>defaultValue

```

I would love to work on a PR to implements one of those solution if this make sense to you.

 

Regards

Start by reviewing Maven core's existing environment-variable interpolation and the two proposed default-value syntaxes in the issue. Decide which approach is appropriate and trace its impact through POM processing. Done means the chosen behavior is specified clearly and covered by relevant tests.
