[MDEP-762] `mvn compile dependency:tree` and `mvn package dependency:tree` outputs different result

**[sify21](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=sify21)** opened **[MDEP-762](https://issues.apache.org/jira/browse/MDEP-762?redirect=false)** and commented

I made a [sample project here](https://github.com/sify21/mvntest).

```java
mvn compile dependency:tree
```

resolves one version of snappy-java

```java
org.xerial.snappy:snappy-java:jar:1.1.4:compile
```

However,

```java
mvn package dependency:tree
```

resolves two version of snappy-java

```java
org.xerial.snappy:snappy-java:jar:1.1.4:compile
org.xerial.snappy:snappy-java:jar:1.1.7.2:compile
```

Start with the linked sample project and run `mvn compile dependency:tree` and `mvn package dependency:tree` against Maven Dependency Plugin 3.0.2. Compare the results with attachments output1 and output2, then establish why the dependency tree differs and verify that the two commands produce consistent resolution.
