MavenGoalReferenceResolver (Helidon Dev Loop 2.2.3 API)

java.lang.Object
- io.helidon.build.dev.maven.MavenGoalReferenceResolver

```
public class MavenGoalReferenceResolver
extends Object
```
Utility to map a Maven goal reference to a MavenGoal. References are resolved in the context of the specified project.

References may be fully qualified:
```
    ${groupId}:${artifactId}:${version}:${goal}@${executionId}
 
```
The version will be ignored since it can only be resolved to the plugin configured in the current project. If not provided, a default executionId will be used. For example, with the compile goal the default execution id is default-compile.

A plugin prefix may be used as an alias for the groupId and artifactId, for example compiler in the following reference:
```
     compiler:compile
 
```
Finally, any lifecycle phase (e.g. process-resources) may be used as a reference, and will expand to the corresponding list of goals.

Example References
1. org.apache.maven.plugins:maven-exec-plugin:3.0.0:exec@compile-sass
2. org.apache.maven.plugins:maven-exec-plugin:exec@compile-sass
3. exec:exec@compile-sass
4. compiler:compile
5. compile
References #1-3 are equivalent, #4 executes only the compile goal and #5 executes all goals in the compile lifecycle.
