I want to use CDI functionality in a java module. I'd like my code to remain generic and do not depend on a particular implementation.
I use Java 11 and Maven 3.6.0.
For a simplicity, my goal is reduced to importing package javax.enterprise.context in a java file. When I do so without module (without module-info.java) every thing works well.
Now when I add a module-info.java without requiring other modules, I get the following error message:
package javax.enterprise.context is not visible (package javax.enterprise.context is declared in the unnamed module, but module javax.enterprise.context does not read it)
Until now everything is OK. This message makes sens since I didn't require the CDI module.
To fix this I add requires cdi.api; to my module-info.java, only to get the following error:
module not found: cdi.api
My understanding is that the CDI library should take an automatic module name inspired by the jar file's name. When I run maven with -X directive I see cdi-api-2.0.jar in my classpath. I believe, correct if I'm wrong, this should translate to cdi.api automatic module name. But still this doesn't work.
Here is my minimal example:
pom.xml:
<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">

<groupId>com.acme</groupId>
<artifactId>test.java.cdi</artifactId>
<packaging>jar</packaging>
<version>1.0-SNAPSHOT</version>
<properties>

<dependency>
<groupId>javax.enterprise</groupId>
<artifactId>cdi-api</artifactId>
<version>2.0</version>
<scope>provided</scope>
</dependency>
</dependencies>
</project>
src/main/java/module-info.java:
module com.acme.test.cid {
requires cdi.api;
}
src/main/java/com/acme/Main.java
package com.acme;
import javax.enterprise.context.*;
class Main {}
Any insights are highly appreciated.
