lanch4Jbin dependency does not recognize aarch64 platform architecture and patch level version number

Problem

gradle-launch4j plugin assumes a workdir package classifier as linux when running on other than x86-64.

I have made forked version of launch4j that have an linux-aarch64 support. You can find it at https://repo1.maven.org/maven2/org/omegat/launch4j/3.50.1/

When specified a configuration

dependencies {
    launch4jBin 'org.omegat:launch4j:3.50.1:workdir-linux-aarch64'
}

I got an error

> Could not create task ':createExe'.
   > Could not create task of type 'Launch4jLibraryTask'.
      > launch4j binary jar workdir-linux file not found! Expected workdir-linux.jar but got [launch4j-3.50.1-workdir-linux-aarch64.jar]. Use the correct classifier for this platform.

It is because

gradle-launch4j/src/main/groovy/edu/sc/seis/launch4j/Launch4jPlugin.groovy

Lines 106 to 113 in 4b6ab73

	} else if (os.isLinux() || os.isUnix()) { // isUnix will also match MacOs, hence, call it as last resort
	String arch = System.getProperty("os.arch")
	if ("amd64" == arch || "x86_64" == arch) {
	return 'workdir-linux64'
	} else {
	return 'workdir-linux'
	}
	}

The plugin assumes there are only linux and linux64.

It is better to respect the configuration or providing a way to mapping among platforms and flavors.

When forked version of launch4j is modified to publish lanuch4j-3.50.2-workdir-linux.jar for aarch64, the plugin download the intended jar file but failed with error message on Ubuntu 24.10 for ARM64

The plugin assumes (specified) launch4j has artifact-id launch4j and version contains 3.50 form hard-coded, and does not respect configured values, e.g., 3.50.1 patch level.

 def jarName = "launch4j-(\\d{1,2}\\.\\d{1,2})-${workingDirName}"

gradle-launch4j/src/main/groovy/edu/sc/seis/launch4j/tasks/DefaultLaunch4jTask.groovy

Lines 246 to 254 in 4b6ab73

	private static File getWorkingJar(ConfigurableFileCollection launch4jBinaryFiles) {
	def workingDirName = Launch4jPlugin.workdir()
	def jarName = "launch4j-(\\d{1,2}\\.\\d{1,2})-${workingDirName}"
	def workingJar = launch4jBinaryFiles.files.find { File file -> file.name =~ /${jarName}.jar/ }
	if (!workingJar) {
	throw new Exception("launch4j binary jar ${workingDirName} file not found! Expected ${workingDirName}.jar but got ${launch4jBinaryFiles.files.collect { it.name }}. Use the correct classifier for this platform.")
	}
	workingJar
	}

The plugin also assumes a hard-coded classifier string got by workDir() instead of user specified one.
