Description

Steps to replicate:

$ mvn archetype:generate

I then entered

• 1313 for the quickstart archetype.

• 8 for quickstart archetype version 1.4.

• info.cameronhudson.18655 for the groupId

• lab1 for the artifactId

• 1.0 for the snapshot version

• public-recommendation-service for the package name

• Y for confirmation

This successfully creates a project, even though the package name is invalid.

Attempting to run mvn clean install results in misleading compilation errors:

[ERROR] COMPILATION ERROR :
[INFO] -------------------------------------------------------------
[ERROR] /Users/cameronhudson/Repositories/CMU/18-655_Lab_1_Public_Recommendation_Service/lab1/src/main/java/public-recommendation-service/App.java:[1,8] <identifier> expected
[ERROR] /Users/cameronhudson/Repositories/CMU/18-655_Lab_1_Public_Recommendation_Service/lab1/src/main/java/public-recommendation-service/App.java:[1,15] class, interface, or enum expected
[INFO] 2 errors

 

Expected behavior:

Inform the user that the package name is invalid (ideally, explaining why it's invalid) and present the prompt again.
