Hi,

is it somehow possible to add or modify the project resp. its properties during 
e.g. validate or initialize with this plugin? 
I defined the following and want 

<properties>
  
<docker-maven-plugin.from>docker.io/library/eclipse-temurin:21.0.9_10-jre-alpine-3.23</docker-maven-plugin.from>
  <java.version>21<java.version>
</properties>

<plugins>
<plugin>
        <artifactId>maven-scripting-plugin</artifactId>
        <version>3.1.0</version>
        <executions>
                <execution>
                        <id>foo</id>
                        <phase>initialize</phase>
                        <goals><goal>eval</goal></goals>
                        <configuration>
                                <engineName>java</engineName>
                                <script><![CDATA[
                                        var props = $project.getProperties();
                                        System.err.println("XXXXX " + 
props.getProperty("docker-maven-plugin.from"));
                                        var version = 
props.getProperty("java.version");
                                        switch (version) {
                                                case "21" -> 
props.setProperty("docker-maven-plugin.from", 
"docker.io/library/eclipse-temurin:21.0.9_10-jre-alpine-3.23");
                                                case "25" -> 
props.setProperty("docker-maven-plugin.from", 
"docker.io/library/eclipse-temurin:25.0.1_8-jre-alpine-3.23");
                                                default -> throw new 
IllegalArgumentException("Not supported“);
                                        }
                                        System.err.println("YYYYY " + 
props.getProperty("docker-maven-plugin.from"));
                                ]]>
                                </script>
                        </configuration>
                </execution>
        </executions>
</plugin>
<plugins>

The println statement are executed and show the „correct“ result, however when 
I lateron reference reference property docker-maven-plugin.from in a plugin it 
still has the value of the definition in the standard properties section.


Mit freundlichen Grüßen
