[~michael-o] How is the link answering the question? This
[line|https://github.com/apache/maven/blob/65ec04c2363b16d08b760fe7e494b56b347bffee/maven-model-builder/src/main/resources/org/apache/maven/model/pom-4.0.0.xml#L93]
shows that the version of maven-dependency-plugin as still 2.8. The new
feature that introduces `(optional)` flag is not available in v2.8, it is in
v3.1.2.
Perhaps we need to make a PR to update maven-depnendency-plugin version as
stated in [this issue|https://issues.apache.org/jira/browse/MNG-6893]?
Please let us know.

> When I run "mvn dependency:tree" with maven 3.6.3 to view the dependency

> For example, I have a pom.xml file like this:

> {code:java}
> <project xmlns="http://maven.apache.org/POM/4.0.0";
> xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";

> I have checked the org.apache:apache:23 where the maven-dependency-plugin is
> managed and the its version is defined as 3.1.1. But the output of
> dependency:tree shows the version is 2.8. So I think it is not an updating
> issue but a bug.
