Spring Tool Suite 17 with maven no longer copies application.properties file to the target folder

[marcgemis]

Describe the bug
When you create a new Spring Boot project (2.76, Maven, Java 17) with Spring Web an application.properties file gets created. When you edit this file, e.g. add server.port=8888 and save the file, the file never appears in the target folder of the project.
This also means that the web application still starts at the default port 8080.

There is no problem with the same project is created with gradle.

Platform MacOS Monterey 12.5.1 Apple M1 chip - Eclipse STS 17.0

To Reproduce
See above

Problem does not occur in STS 14

A non-working maven project, and a working gradle project

I can reproduce this and I think this is a problem with the m2e integration in Eclipse (since I can reproduce this with Eclipse 2022-12 RC1 JEE package as well), therefore I reported this issue via eclipse-m2e/m2e-core#1148 to the m2e project.

Here is the issue from the m2e project where this got fixed: eclipse-m2e/m2e-core#1150 - now waiting for a new release of m2e to be published that includes this fix.

thanks for keeping me updated

In case you want to try the fix early, you can add the m2e snapshots update site to the preferences (Preferences -> Install/Update -> Available Update Sites, then add https://download.eclipse.org/technology/m2e/snapshots/latest/) and run a Check for Updates.

Feel free to uncheck the JustJ JRE update, but keep everything else selected and run the update. It includes the fix for this issue.
