Module resolution exeption with odfdom and Gradle

Question

I am modulirizing and existing non modular application. To make my life easier with the Java modules system, I decided to pick up a working example https://github.com/beryx-gist/badass-jlink-example-log4j2-javafx which is similar to my app and add the depencies I will need to that and make it work. I started with odfdom, a I am processing lot of OpenDocument spreadsheets using jOpenDocument, but odfdom looks now more promising so I am moving to that. I get the following error when running the example:

java.lang.module.ResolutionException: Modules maven.core and maven.artifact export package org.apache.maven.artifact.repository to module org.json

This occurs when I add the following line to the buid.gradle:

implementation 'org.odftoolkit:odfdom-java:0.10.0'

otherwise the project builds and runs as expected. How I am supposed to solve this issue? Here is the build.gradle:

plugins {
    id 'application'
    id 'org.javamodularity.moduleplugin' version '1.8.9'
    id 'org.openjfx.javafxplugin' version '0.0.10'
    id 'org.beryx.jlink' version "2.24.1"
}

repositories {
    mavenCentral()
}

sourceCompatibility = "11"
targetCompatibility = "11"

dependencies {
    implementation 'org.apache.logging.log4j:log4j-core:2.11.1' //automatic-module
    implementation 'com.google.code.gson:gson:2.9.1' //module
    implementation 'org.odftoolkit:odfdom-java:0.10.0' //none
}

javafx {
    version = 16
    modules = ['javafx.controls']
}

application {
    mainClass = "org.openjfx.HelloFX"
    mainModule = "hellofx"
}

and the module-info.java:

module hellofx {
    requires javafx.controls;
    requires org.apache.logging.log4j;
    
    exports org.openjfx;
}

I think you may need to add to module-info.java the module name for implementation 'org.odftoolkit:odfdom-java:0.10.0':

requires odfdom.java;

I am not getting your error but getting lots of other module errors eg

 .... module reads package org.apache.maven.settings from both maven.settings and maven.core

Solution for me was to add some excludes in my build.gradle in order to get it to compile:

     configurations {
         compileOnly.exclude group: 'xerces', module: 'xercesImpl'       
         // exclude from compile but allow at run time  
     }
     

     implementation (group: 'org.odftoolkit', name: 'odfdom-java', version: '0.10.0') {         
        exclude group: 'org.apache.maven', module: 'maven-core'
        exclude group: 'org.apache.maven', module: 'maven-plugin-api'
        exclude group: 'io.github.git-commit-id', module: 'git-commit-id-plugin-core'
     }

My build.gradle is more complex that yours and I seemed to get a lot of module clashes and so it's not the same issue, but I hope this points you in the right direction.
