Can jfreechart 1.5.3 be used with jlink to create a self contained executable?

[AlexHomebrew]

I am adding charts to a large legacy project created in Netbeans and chose jfreechart. I have already migrated the project from Java 8 to JDK 15.0.2 and Netbeans 15, which included modularization. I added jlink to create a self contained executable so my customers don't have to install java. So far, all my installations are in Windows 10.

When I compile (in Netbeans using Maven) I get the following error:
Error: automatic module cannot be used with jlink: org.jfree.jfreechart from file:///C:/Users/AlexXX/.m2/repository/org/jfree/jfreechart/1.5.3/jfreechart-1.5.3.jar
Command execution failed.
org.apache.commons.exec.ExecuteException: Process exited with an error: 1 (Exit value: 1)
at org.apache.commons.exec.DefaultExecutor.executeInternal (DefaultExecutor.java:404)
. . .

Is there a way to modularize jfreechart so it doesn't rely on being an automatic module?
Or more to the point, can I create an executable that includes everything it needs (like jlink creates) with jfreechart?
Or, is JFreeChart 2.0 coming out soon?
Thanks,
Alex

JFreeChart version 2.0.0 is modular but not yet released. I haven't tried jlink with it, but you should be able to build, install and require it like this. Alternatively, JFree Demos illustrates using the maven-assembly-plugin to create a JAR with dependencies.

I created a Hack that allowed me to build with jlink and include JFreeChart-1.5.3.

1. Download the source code into a new Netbeans project called JFreeChart.
2. Create a new file: JFreeChart/src/main/java/module-info.java containing the following

module jfreechart
{
    requires java.desktop;
    requires java.logging;
    requires java.sql;

    exports org.jfree.chart;
    exports org.jfree.chart.axis;
    exports org.jfree.chart.plot;
    exports org.jfree.chart.renderer.xy;
    exports org.jfree.chart.ui;
    exports org.jfree.data.time;
}

3. Remove the package (and contents) org.jfree.chart.servlet
4. Add requires jfreechart; to my project's module-info.java

JLink now is happy and builds the project, which runs. I still have to verify that I can create a chart and display it.
Note that my project doesn't need the servlet functionality and I removed it because the servlet.api is not modularized so jlink was unhappy. Fortunately, it was self contained (as good designs should be) so I didn't need to modify anything else. As I build more charts, I may need to add more exports, but that is easy.

I will report back after I create some working charts.

Will this be a configuration management problem going forward? Version 2 already elides servlets, and jlink should optimize the rest. For reference, this gist illustrates migrating a Swing application; see tag v2modular.

You are correct @trashgod it will, as most hacks are. But I need to move forward now and I am expecting to have some other changes when upgrading to JFreeChart 2.0. I am documenting what I did to minimize that effort. Thanks for your feedback.

My chart is displaying great (thank you to David Gilbert)
