I have Spring-Boot Eclipse project which displays the subject message in the eclipse problems. My single test method in org.test.Test is:

package org.test;
public class Test
{
    public static void main(String[] strings) {
    }
}

my module-info.java is:

open module ws.daley.pihome.environ
{
    exports org.test;

    requires com.google.gson;
}

my pom.xml is:

<?xml version="1.0" encoding="UTF-8"?>

</project>

In the module_info.java file, the line:

    requires com.google.gson;

is flagged and com.google.gson is underlined in red.

I’m running Spring Tool Suite 4.22.1, Eclipse 2024-06, and Java Zulu21.34+19-CA.

How do I resolve the error?
