Adding .gitattributes to archetype-metadata.xml. Fixes #825.

[GuillaumeCleme]

Description

Adding .gitattributes to archetype-metadata.xml. File previously added in #661 but missing from new projects when using the mvn -B archetype:generate command.

Related Issue

• Relates to Dispatcher immutable files pushed/cloned with invalid line endings #661
• Fixes Dispatcher immutable files pushed/cloned with invalid line endings #825

Motivation and Context

In certain development environments that may be configured with different GIT line ending configurations, it is possible for developers to unwillingly commit files with invalid line endings which will break the Dispatcher module's immutable file check due to invalid MD5 hashes.

How Has This Been Tested?

Yes. Steps included:

• Adding changes locally
• Building archetype project with mvn clean install -Pit-basic
• Run mvn -B archetype:generate ... -DarchetypeVersion=31-SNAPSHOT
• Confirm presence of .gitattributes in new project
