[MDEP-556] The dependency:resolve goal tries to resolve all dependencies, regardless of the exclude filters

**[Yoann Rodière](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=yrodiere)** opened **[MDEP-556](https://issues.apache.org/jira/browse/MDEP-556?redirect=false)** and commented

My use case was to download dependencies in a CI script, before executing the build. To that end, I wanted to execute something along the lines of:

```
mvn -q -B dependency:resolve -DexcludeArtifactIds='hibernate-search-integrationtest-wildfly'
```

... `hibernate-search-integrationtest-wildfly` being a module that other modules in my project depend on.

But I get this stacktrace:

```

I think I know why this fails: when one executes the `dependency:resolve` goal, there is a first dependency resolution requested by the mojo executor, because [the resolve mojo is marked as requiring resolution of test-scoped dependencies](https://github.com/apache/maven-plugins/blob/trunk/maven-dependency-plugin/src/main/java/org/apache/maven/plugins/dependency/resolvers/ResolveDependenciesMojo.java#L42).
I am not sure why the `dependency:resolve` mojo would require this, though... It seems odd, considering that the purpose of this mojo is to perform dependency resolution.

Start with ResolveDependenciesMojo.java, especially the requirement for test-scoped dependency resolution linked in the issue, and trace how Maven invokes dependency:resolve before the mojo runs. Reproduce the command with the excludeArtifactIds option; done means excluded artifacts are not resolved while the requested dependencies still are.
