RFE: remove license from some of the generated files

[delabassee]

Environment Details

• Helidon Version: NA
• Helidon SE or Helidon MP : NA
• JDK version: NA
• OS: NA

---

Problem Description

Right now some of the generated files (mvn archetype:generate) are embedding a license, ex. Dockerfile, app.yaml & application.yaml. If possible to would be nice to remove them in such a case as

• the singal-to-noise ratio is very high (80%-90%)
• those license block are not collapsable (YAML limitation)

There are a few files that are not yet fixed:

1. app.yaml in both SE and MP quickstarts
2. pom.xml in MP quickstart

All other files are fixed.

Is it issue still valid after #4887 ?

The license header is also being generated for the src/main/resources/META-INF/native-image/native-image.properties file for the Database SE archetype of version 3.x.

However, perhaps this file should be removed because two native-image.properties files are being generated for this archetype.

The generation of a native-image.properties file is already defined in archetype/common/files/src/main/resources/META-INF/native-image/__dir__/native-image.properties.mustache.

Also, the src/main/resources/META-INF/native-image/native-image.properties file only sets -H:+RemoveSaturatedTypeFlows, which is enabled by default since GraalVM 20.2.0 (2020-08-18).

The Database MP archetype of version 3.x also has a file for native-image.properties generation setting Args=-H:+RemoveSaturatedTypeFlows, but this file is being ignored. It is not generated.

https://github.com/helidon-io/helidon/blob/helidon-3.x/archetypes/helidon/src/main/archetype/mp/database/files/src/main/resources/META-INF/native-image/native-image.properties

So maybe it should be deleted as well. Although this one doesn't have the license header.

@tvallin can you take a look

I think all the copyright header had been removed. Thanks @felvid for your help.
