[MASSEMBLY-946] Dependency resolve issues when using revision variable for the project version

**[Muris Ahmovic](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=grandon)** opened **[MASSEMBLY-946](https://issues.apache.org/jira/browse/MASSEMBLY-946?redirect=false)** and commented

I have a multi-module project and use the ${revision} variable for versioning. The assembly plugin execution happens in one of the child modules.

root pom:

```java
[...]
group
root
${revision}
[...]

1.0.0-SNAPSHOT

[...]
```

child pom:

```java
[...]

group
root
${revision}

[...]
```

The build is successful, but I get some warnings and I can see that the ${revision} variable is used instead of 1.0.0-SNAPSHOT

```java
[WARNING] Failed to build parent project for group:child:jar:1.0.0-SNAPSHOT

Could not find artifact group:root:pom:${revision} in central
```

---

**Affects:** 3.3.0

Reproduce the warning with the root and child POM setup shown in the issue, using the assembly plugin in the child module and the ${revision} project version. Start by examining dependency and parent-project resolution during the Maven build. Done means the build no longer tries to resolve group:root:pom:${revision} or emits the reported warning.
