MappingUtils (Apache Maven Mapping 3.0.0 API)

java.lang.Object
- org.apache.maven.shared.mapping.MappingUtils

```
public final class MappingUtils
extends Object
```
Utilities used to evaluate an expression.

The expression might use any field of the Artifact interface. Some examples might be:
- @{artifactId}@-@{version}@@{dashClassifier?}@.@{extension}@
- @{artifactId}@-@{version}@.@{extension}@
- @{artifactId}@.@{extension}@
Although parts of this code comes from the Assembly Plugin, it cannot be shared with the Assembly Plugin. The reason for this is that the Assembly Plugin always uses a prefix for the expressions, whereas this code does not.
