Usage

From source file:com.google.jenkins.plugins.persistentmaster.volume.zip.ZipCreator.java

private void copySymlink(Path file, String filenameInZip) throws IOException {
    logger.finer("Adding symlink: " + file + " with filename: " + filenameInZip);
    Path symlinkTarget = Files.readSymbolicLink(file);
    // Unfortunately, there is no API method to create a symlink in a ZIP file,
    // however, a symlink entry can easily be created by hand.
    // The requirements for a symlink entry are:
    //  - the unix mode must have the LINK_FLAG set
    //  - the content must contain the target of the symlink as UTF8 string
    ZipArchiveEntry entry = new ZipArchiveEntry(filenameInZip);
    entry.setUnixMode(entry.getUnixMode() | UnixStat.LINK_FLAG);
    zipStream.putArchiveEntry(entry);//from  w ww.  j  av  a 2 s  . com
    zipStream.write(symlinkTarget.toString().getBytes(StandardCharsets.UTF_8));
    zipStream.closeArchiveEntry();
