[ARCHETYPE-547] triple underlines

**[Dorin Brage](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=dorin.brage@gmail.com)** opened **[ARCHETYPE-547](https://issues.apache.org/jira/browse/ARCHETYPE-547?redirect=false)** and commented

Let's say you have the next path

```java
/src/main/resources/50____rootArtifactId__.ui/
|---local___rootArtifactId__.properties
|---prod___rootArtifactId__.properties
```

I want to achieve 

 

```java
/src/main/resources/50_demoApp.ui/
|---local_demoApp.ui.properties
|---prod_demoApp.ui.properties
```

The console output

 

```java
[WARNING] Property '_rootArtifactId' was not specified, so the token in 'src/main/resources/////50___rootArtifactId__.ui/local___rootArtifactId__.properties
```

 

Workaround 

Avoid adding as a prefix/suffix extra underlines

```java
50.__rootArtifactId__.ui
```

Reproduce the issue with the shown /src/main/resources/50____rootArtifactId__.ui/ layout and compare it with the 50_demoApp.ui/ target layout. Start by tracing Maven Archetype's resource-path token processing and verify that extra underscores are preserved correctly while _rootArtifactId is substituted without producing the warning's malformed path.
