Method

voidextract(Path archive, Path targetDirectory)
Extracts a ZIP archive into the target directory 
System.out.println("Unzipping " + archive.getFileName().toString() + "...");
byte[] buffer = new byte[bufferSize];
try (ZipInputStream zin = new ZipInputStream(new FileInputStream(archive.toFile()))) {
    ZipEntry ze;
    while ((ze = zin.getNextEntry()) != null) {
        Path extractedFile = targetDirectory.resolve(ze.getName());
        try (FileOutputStream fout = new FileOutputStream(extractedFile.toFile())) {
            int len;
...
StringextractClassName(Path path)
Extracts the actual Class-Name from the given Path which should be a Path to a Class-File

If the given Path does not discribe a Class-File the result may be completly unusable 

String className = path.toString();
return className.substring(1, className.length() - CLASS_FILE_ENDING.length()).replace('/', '.');
StringextractCurrentPath()
extract Current Path 
return Paths.get(".").toAbsolutePath().normalize().toString();
voidextractFile(ZipInputStream zipIn, Path filePath)
Extracts a zip entry (file entry) 
BufferedOutputStream bos = new BufferedOutputStream(
        new FileOutputStream(filePath.toFile().getAbsolutePath()));
byte[] bytesIn = new byte[BUFFER_SIZE];
int read = 0;
while ((read = zipIn.read(bytesIn)) != -1) {
    bos.write(bytesIn, 0, read);
bos.close();
...
StringextractLanguageRelativePath(final Path absolutePath)
extract Language Relative Path 
final String fileName;
if (absolutePath != null && absolutePath.getFileName() != null) {
    fileName = absolutePath.getFileName().toString();
} else {
    fileName = "";
final String pathRegexSeparator;
if ("\\".equals(File.separator)) {
...
StackTraceElement[]extractLuaStacktrace(Path path, StackTraceElement[] stackTrace)
extract Lua Stacktrace 
if (stackTrace == null || stackTrace.length == 0) {
    return new StackTraceElement[0];
List<StackTraceElement> luaStackTrace = new ArrayList<>();
String pathAsString = path.toString().replace('.', '/');
for (StackTraceElement stackTraceElement : stackTrace) {
    String fileName = stackTraceElement.getFileName();
    if (fileName != null && fileName.startsWith(pathAsString)) {
...
StringextractVersion(Path pathToBinaries)
extract Version 
return pathToBinaries.getParent().getFileName().toString();
voidextractZipArchive(final File zipFile, Path destDir)
extract Zip Archive 
if (!destDir.toFile().exists() || !destDir.toFile().isDirectory()) {
    throw new IllegalArgumentException("can only unzip to directory");
if (!zipFile.exists()) {
    throw new IllegalArgumentException("zip file not found");
try (FileSystem zipFileSystem = FileSystems.newFileSystem(zipFile.toPath(), null)) {
    final Path root = zipFileSystem.getPath("/");
...
voidunzipFileInArchive(FileChannel channel, String relpathInZip, File extractTo)
unzip File In Archive 
relpathInZip = relpathInZip.replace("\\", "/");
Pattern pattern = Pattern.compile(wildcardToRegex(relpathInZip), Pattern.CASE_INSENSITIVE);
ZipInputStream stream = new ZipInputStream(Channels.newInputStream(channel));
ZipEntry entry;
while ((entry = stream.getNextEntry()) != null) {
    File file = new File(extractTo, entry.getName());
    String name = '/' + entry.getName();
    Matcher matcher = pattern.matcher(name);
