Description

The commons-beanutils jar doesn't support Java modules:

[INFO] --- maven-compiler-plugin:3.11.0:compile (compile-java9) @ opencsv ---
[WARNING] ***************************************************************************************************************************************************
[WARNING] * Required filename-based automodules detected: [commons-beanutils-1.9.4.jar]. Please don't publish this project to a public artifact repository! *
[WARNING] ***************************************************************************************************************************************************

At the very least the manifest could define an Automatic-Module-Name but preferably the project should be configured to build a multi-release jar that can support Java 8 while also compiling a module-info targeting a newer JDK such as 11. 

 

here is an example maven profile that can be used to ensure that a module-info gets included when a project is built with JDK 9 or above:

<profile>
    <id>jpms</id>
    <activation>
        <jdk>[9,)</jdk>
    </activation>
    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <executions>
                    <execution>
                        <id>compile-java9</id>
                        <phase>compile</phase>
                        <goals>
                            <goal>compile</goal>
                        </goals>
                        <configuration>
                            <release>9</release>
                            <compileSourceRoots>
                                <compileSourceRoot>${project.basedir}/src/main/java9</compileSourceRoot>
                            </compileSourceRoots>
                            <multiReleaseOutput>true</multiReleaseOutput>
                        </configuration>
