[ARCHETYPE-629] Lexical Error when archetype-resource contains excel file

**[Deepak](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=JIRAUSER289216)** opened **[ARCHETYPE-629](https://issues.apache.org/jira/browse/ARCHETYPE-629?redirect=false)** and commented

I have created an archetype where my archetype-resources under src/main/resources contains an template excel that will get copied when a project will be created out of it. While executing the archetype:generate on this, it throws lexical error while creating the excel file.

Exception Trace:

```java

**Affects:** 3.2.1

Start with DefaultFilesetArchetypeGenerator.processTemplate and processTemplates, then reproduce the failure with archetype:generate using an .xlsx file under archetype-resources. Determine how binary resources are distinguished from Velocity templates; done means the Excel file is copied without a lexical error while ordinary templates still process correctly.
