Well i import this org.apache.poi dependency to my project to export a word file.

    <dependency>
      <groupId>org.apache.poi</groupId>
      <artifactId>poi-ooxml</artifactId>
      <version>5.2.3</version>
    </dependency>

But it comes to an error when i was packaging the proj, i try to import the module which was not founded, but it always comes out another "module not found" error.

[ERROR]  Exception in thread "main" java.lang.module.FindException: Module commons.math3 not found, required by org.apache.poi.poi

I guess there is a conflict between "org.apache.poi" and JavaPackager because when i deleted the dependency, the Packager works correctly.

Please tell us about your environment:

• JavaPackager version:1.7.5
• OS version:Windows11
• JDK version:17.0.9
• Build tool:
  • Maven
  • Gradle

I also encountered the same problem.

Hi @chenyany and @payfish!
I haven't found a solution for this issue yet ... a work around is to set customizedJre=false and bundle a full JRE, or manually specify modules (but this is a bit tedious). jdeps is used to find out which core modules are needed in order to generate a minimal JRE, including only those core modules, but not sure why some non-modular JARs cause this problem. I'd really appreciate it if you could give me some hint on what options JP should pass to jdeps to solve this problem.
Thanks!

I researched again about this issue and found this answer in StackOverflow, then I tried to add --add-modules=ALL-MODULE-PATH to jdeps call as explained, and it seems to be working fine. 😮

I've only tried adding the poi-ooml dependency to the pom.xml file and it bundles a customized JRE without errors, so I released a SNAPSHOT version, so you can check it: 1.7.6-20240416.203813-5.

Changes were pushed into issue-399 branch.

Please, give me some feedback.

Thanks!!

Doing some tests I just realized that jdeps can't find all needed modules when using a fat jar 😢

When using a normal jar with dependencies in libs folder, app runs fine:

When using fat jar, app fails due to missing modules in JRE:

Thank you!! Things works well with the SNAPSHOT version! But here is some little question: when I import the SNAPSHOT plugin I encountered an "Unresolved plugin" error, but I can still package my proj with it, despite the maven sync error.

I'm not familiar with jdeps so I'm sorry that I can't help, But I believe you have found out the correct anwser to solve this problem. Your work helps me a lot! I appreciate for your time and thank you truely!

Please, could you post here the error message?
