Disabling compression in remapJar task causes a ZipException

[chylex]

The following task configuration:

tasks.remapJar {
	entryCompression = ZipEntryCompression.STORED
}

fails with the following exception:

org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':Fabric:remapJar'.
Caused by: org.gradle.workers.internal.DefaultWorkerExecutor$WorkExecutionException: A failure occurred while executing net.fabricmc.loom.task.RemapJarTask$RemapAction

It would be useful to have the option to produce uncompressed jars, as it seems to lead to smaller multiloader jars if the nested jars are uncompressed.

A simple workaround is to create a second jar task that re-creates the output of remapJar:

tasks.register<Jar>("uncompressedRemapJar") {
	group = "fabric"
	
	from(tasks.remapJar.map { it.outputs.files.map(::zipTree) })

	archiveClassifier.set("uncompressed")
	entryCompression = ZipEntryCompression.STORED
}
