Issue
I am trying to keep up with the new changes in Java, one step a time.
I am updating my old libraries with module-info.java files.
I have a very simple project named "api-clone" dependent on "gwt-user".
pom.xml:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<maven.compiler.target>17</maven.compiler.target>

</project>
With the module-info.java below:
open module com.tugalsan.api.clone {
requires gwt.user;
}
When netbeans runs compile, it builds successfully:
cd C:\me\codes\GWT\api\api-clone; "JAVA_HOME=C:\\Program Files\\Eclipse Adoptium\\jdk-17.0.2.8-hotspot" cmd /c "\"C:\\Program Files\\NetBeans-13\\netbeans\\java\\maven\\bin\\mvn.cmd\" \"-Dmaven.ext.class.path=C:\\Program Files\\NetBeans-13\\netbeans\\java\\maven-nblib\\netbeans-eventspy.jar\" -Dfile.encoding=UTF-8 clean install"

However, when I look at the module-info.java file, Netbeans show error:
- Is it because "gwt.user" is not a module-ized project?
- How to handle that kind of projects, when ones projects are dependent on them?
Solution
As @skomisa answered, the problem I am facing in "module-info.java"
can be solved in "pom.xml" by adding exclusion on dependecy tag.
<dependencies>
<dependency>
<groupId>com.google.gwt</groupId>
<artifactId>gwt-user</artifactId>
<exclusions>
<exclusion>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
</exclusion>
</exclusions>
<version>2.9.0</version>
<scope>provided</scope>
</dependency>
</dependencies>
