Why does Maven not find org.json JPMS automatic module?-CodePudding

I have a small test project, containing 2 files:

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">
    <modelVersion>4.0.0</modelVersion>

    <groupId>org.example</groupId>
    <artifactId>test</artifactId>
    <version>1.0.0-SNAPSHOT</version>

    <properties>
        <maven.compiler.source>17</maven.compiler.source>
        <maven.compiler.target>17</maven.compiler.target>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.json</groupId>
            <artifactId>json</artifactId>
            <version>20210307</version>
        </dependency>
    </dependencies>
</project>

and src/main/java/module-info.java:

module org.example.test {
    requires org.json;
}

When I compile with Temurin 17:

openjdk version "17" 2021-09-14
OpenJDK Runtime Environment Temurin-17 35 (build 17 35)
OpenJDK 64-Bit Server VM Temurin-17 35 (build 17 35, mixed mode, sharing)

And Maven 3.6.3 packaged with IntelliJ IDEA, I get this error:

src/main/java/module-info.java:[2,17] module not found: org.json

The json-20210307.jar file contains this line in META-INF/MANIFEST.MF:

Automatic-Module-Name: org.json

What further do I need to do to use JPMS in Maven?

CodePudding user response：

If you run mvn help:effective-pom you will notice that the project uses the maven compiler version that may be a bit dated. Try explicitly using a newer version and see how it changes things:

<build>
    <pluginManagement>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.8.1</version> <!-- current version -->
            </plugin>
        </plugins>
    </pluginManagement>
</build>
