Why annotation processor doesn't work with Maven and java11?

I'm migrating a Java webapp from Java8 to Java17.
This project uses this very nice solution to embed strings (ex. SQL queries) in constanst:
https://github.com/adrianwalker/multiline-string
This library requires the annotation processor.

With the old version I could run "mvn clean install" to get the war file of my application, this process correctly processed annotations. I had just to add the library in the pom dependencies.

Now using java17 the annotation doesn't work. Then I tried to use in my Eclipse IDE and here the compilation doesn't work too.

Then I tried to downgrade to Java11 and I could start the project from Eclipse, setting the library as annotation processor in java compile option of Eclipse.
Finally I tried the maven install, it completed successfully but the annotations are not processed.

This is my pom.xml

I also tried to add this option in maven compilter plugin settings of pom.xml

<configuration>
<annotationProcessors>
<annotationProcessor>
org.adrianwalker.multilinestring.MultilineProcessor</annotationProcessor>
</annotationProcessors>
</configuration>

I cannot understand why Eclipse can compile and run the application with annotations, it can also export valid ROOT.war, but Maven ignores (without errors) completely the annotations.

Do you have any idea why maven doesnt run the annotation processor?
Do you know how can I get the eclipse command called when I export WAR file from a project?

EDIT

These are the versions:
Apache Maven 3.8.7
Java version: 17.0.7
Eclipse Version: 2023-03 (4.27.0)
M2E Maven Integration for Eclipse: 2.2.1.20230307-1553

Java 17 supports multi line strings directly in code (so-called text blocks).

Instead of making some ancient hack work again, just refactor to modern Java.
