We need to change the LICENSE (our file in the root repository) to Apache 2.0 (because of the code coming in - and we don't want to maintain multiple licenses) -

the module javafx iis not found @koppor

Resolution ambiguation, so the mapping is not applied..

 Could not resolve all dependencies for configuration ':mvvmfx-validation:compileClasspath'.
   > Could not resolve org.openjfx:javafx-base.
     Required by:
         project ':mvvmfx-validation'
      > The consumer was configured to find a library for use during compile-time, compatible with Java 24, packaged as a jar, preferably optimized for standard JVMs, and its dependencies declared externally, as well as attribute 'javaModule' with value 'true'. However we cannot choose between the following variants of org.openjfx:javafx-base:24:
          - compile
          - linux-aarch64Compile
          - linuxCompile
          - mac-aarch64Compile
          - macCompile
          - winCompile
        All of them match the consumer attributes:
          - Variant 'compile' capability 'org.openjfx:javafx-base:24' declares a library for use during compile-time, packaged as a jar:
              - Unmatched attributes:
                  - Doesn't say anything about how its dependencies are found (required its dependencies declared externally)
                  - Doesn't say anything about its target Java environment (preferred optimized for standard JVMs)
                  - Doesn't say anything about its target Java version (required compatibility with Java 24)
                  - Doesn't say anything about javaModule (required 'true')
                  - Provides attribute 'org.gradle.native.architecture' with value 'none' but the consumer didn't ask for it
                  - Provides attribute 'org.gradle.native.operatingSystem' with value 'none' but the consumer didn't ask for it
                  - Provides release status but the consumer didn't ask for it
          - Variant 'linux-aarch64Compile' capability 'org.openjfx:javafx-base:24' declares a library for use during compile-time, packaged as a jar:

Skipping 'org.openjfx:javafx-base' - no mapping - run ':analyzeModulePath' for more details

@jjohannes May I ask for some help here? I have troubles with the javafx configuration. I copied, adjusted and verified the gradle plugin files etc and compared them with JabRef's setup but somehow the mapping is not found and this results in ambigous resolution of javafx. It's probably some simple stupid thing I overlooked, but I am unable to spot it. Any help would be appreciated 🙏
