[SOLVED] Modules not found when trying to inject module-info.java

Modules not found when trying to inject module-info.java

I have a JavaFX project that uses Apache's PDFBox. I want to use JLink to build a JRE of it, but I can't since PDFBox is an automodule. Thus, I'm trying to inject a module-info file in it.

I generated this module-info file using jdeps:

module org.apache.pdfbox {
    requires org.bouncycastle.pkix;
    requires org.bouncycastle.provider;

    requires transitive commons.logging;
    requires transitive java.desktop;
    requires transitive java.xml;
    requires transitive org.apache.fontbox;

    exports org.apache.pdfbox.contentstream;
    exports org.apache.pdfbox.contentstream.operator;
    exports org.apache.pdfbox.contentstream.operator.color;
    exports org.apache.pdfbox.contentstream.operator.graphics;
    exports org.apache.pdfbox.contentstream.operator.markedcontent;
    exports org.apache.pdfbox.contentstream.operator.state;
    exports org.apache.pdfbox.contentstream.operator.text;
    exports org.apache.pdfbox.cos;
    exports org.apache.pdfbox.filter;
    exports org.apache.pdfbox.io;
    exports org.apache.pdfbox.multipdf;
    exports org.apache.pdfbox.pdfparser;
    exports org.apache.pdfbox.pdfwriter;
    exports org.apache.pdfbox.pdmodel;
    exports org.apache.pdfbox.pdmodel.common;
    exports org.apache.pdfbox.pdmodel.common.filespecification;
    exports org.apache.pdfbox.pdmodel.common.function;
    exports org.apache.pdfbox.pdmodel.common.function.type4;
    exports org.apache.pdfbox.pdmodel.documentinterchange.logicalstructure;
    exports org.apache.pdfbox.pdmodel.documentinterchange.markedcontent;
    exports org.apache.pdfbox.pdmodel.documentinterchange.prepress;
    exports org.apache.pdfbox.pdmodel.documentinterchange.taggedpdf;
    exports org.apache.pdfbox.pdmodel.encryption;
    exports org.apache.pdfbox.pdmodel.fdf;
    exports org.apache.pdfbox.pdmodel.font;
    exports org.apache.pdfbox.pdmodel.font.encoding;
    exports org.apache.pdfbox.pdmodel.graphics;
    exports org.apache.pdfbox.pdmodel.graphics.blend;
    exports org.apache.pdfbox.pdmodel.graphics.color;
    exports org.apache.pdfbox.pdmodel.graphics.form;
    exports org.apache.pdfbox.pdmodel.graphics.image;
    exports org.apache.pdfbox.pdmodel.graphics.optionalcontent;
    exports org.apache.pdfbox.pdmodel.graphics.pattern;
    exports org.apache.pdfbox.pdmodel.graphics.shading;
    exports org.apache.pdfbox.pdmodel.graphics.state;
    exports org.apache.pdfbox.pdmodel.interactive.action;
    exports org.apache.pdfbox.pdmodel.interactive.annotation;
    exports org.apache.pdfbox.pdmodel.interactive.annotation.handlers;
    exports org.apache.pdfbox.pdmodel.interactive.annotation.layout;
    exports org.apache.pdfbox.pdmodel.interactive.digitalsignature;
    exports org.apache.pdfbox.pdmodel.interactive.digitalsignature.visible;
    exports org.apache.pdfbox.pdmodel.interactive.documentnavigation.destination;
    exports org.apache.pdfbox.pdmodel.interactive.documentnavigation.outline;
    exports org.apache.pdfbox.pdmodel.interactive.form;
    exports org.apache.pdfbox.pdmodel.interactive.measurement;
    exports org.apache.pdfbox.pdmodel.interactive.pagenavigation;
    exports org.apache.pdfbox.pdmodel.interactive.viewerpreferences;
    exports org.apache.pdfbox.printing;
    exports org.apache.pdfbox.rendering;
    exports org.apache.pdfbox.text;
    exports org.apache.pdfbox.util;
    exports org.apache.pdfbox.util.filetypedetector;
}

At the jar's folder, I ran: javac --patch-module org.apache.pdfbox=pdfbox-2.0.20.jar module-info.java

But then I got

pdfbox/module-info.java:2: error: module not found: org.bouncycastle.pkix
    requires org.bouncycastle.pkix;
                             ^
pdfbox/module-info.java:3: error: module not found: org.bouncycastle.provider
    requires org.bouncycastle.provider;
                             ^
pdfbox/module-info.java:5: error: module not found: commons.logging
    requires transitive commons.logging;
                               ^
pdfbox/module-info.java:8: error: module not found: org.apache.fontbox
    requires transitive org.apache.fontbox;
                                  ^
4 errors

How can I fix this? Is there any better workaround? Thanks in advance.

Solution

You cannot use jlink directly because of the automatic module issue. But you can follow this tutorial https://github.com/dlemmermann/JPackageScriptFX which also uses jlink but only to create a dedicated runtime without having to modularize your project. I am also using PDFBox in my project, so I know it works. Disclaimer: I am biased because I am the co-author of the above mentioned tutorial :-)
