Answer 1

I managed to create a custom Jar file with its own manifest file like so:

task createJar(type : Jar) {
    manifest {
        attributes(
            'Manifest-Version': "1.0",
            'Main-Class': "org.springframework.boot.loader.JarLauncher",
            'Start-Class': "com.my.app.AppApplication",
            'Spring-Boot-Version': "2.2.4.RELEASE",
            'Spring-Boot-Classes': "BOOT-INF/classes/",
            'Spring-Boot-Lib': "BOOT-INF/lib/"
        )
    }
    def originDir = file("${buildDir}/unpacked")
    def destinationFile = "${buildDir}/repackaged/${project.name}-${version}"
    entryCompression ZipEntryCompression.STORED // no compression in case there are files in BOOT-INF/lib
    archiveName destinationFile
    from originDir
    archiveFile
}
