[MDEP-947] optionally import listed “dependency packages” for analyse-only

**[Thorsten Glaser](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=mirabilos)** opened **[MDEP-947](https://issues.apache.org/jira/browse/MDEP-947?redirect=false)** and commented

I’m working through the Spring Boot tutorial, and it uses packages like org.springframework.boot:spring-boot-starter-web that contain empty JARs but a lot of dependencies.

Instead of doing…

```java

org.springframework.boot:spring-boot-starter-test
org.springframework.boot:spring-boot-starter-web



org.springframework:spring-context
org.springframework.boot:spring-boot-test
org.springframework:spring-web
org.springframework.boot:spring-boot
org.junit.jupiter:junit-jupiter-api
org.springframework.boot:spring-boot-autoconfigure

```

… or replacing them by the depended-on packages, for convenience (when the user does want to allow relaxing the dependency rules for this), there could be something like…

```java

org.springframework.boot:spring-boot-starter-web
[…]
```

… with which I’d whitelist one or more specific dependencies I have for “ignore if this one is unused” and “ignore if any of **its** dependencies are used but undeclared” (but no warning if (also explicitly) declared).

Does this make sense?

No further details from [MDEP-947](https://issues.apache.org/jira/browse/MDEP-947?redirect=false)

No files, tests, or entry points are named. Start by reviewing the plugin's dependency-analysis configuration and how ignored unused and undeclared dependencies are handled; done would mean supporting an importDependencyPackages configuration that applies both ignore rules to the selected packages and their dependencies.
