The above pom.xml does not throw any issue but it is not creating any binaries for windows and also i am unable to understand what options i could use for WINDOWS.


Solution

  • Not familiar with the issues around mac executables

    These 2 configurations will be joined together, you probably don't need the jni library section if you are aiming for an executable.

            <libraries>
                <library>
                    <type>jni</type>
                    <narSystemPackage>com.github.maven-nar</narSystemPackage>
                </library>
            </libraries>
    
            <libraries>
                <library>
                    <type>executable</type>
                    <!-- <run>true</run> -->
                    <subSystem>gui</subSystem>
                </library>
            </libraries>
    

    This section might work

    But generally would do it as

            <defines>
                <define>WINDOWS</define>
                <define>__CF_USE_FRAMEWORK_INCLUDES__</define>
                <define>LARGE64_FILES</define>
            </defines>
