如何在Install4j自定义代码和资源文件选项中使用tar.gz

import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.util.zip.GZIPInputStream;
import java.util.zip.TarInputStream;

public void run() throws Exception {
    File tarGzFile = new File(context.getInstallationDirectory(), "yourfile.tar.gz");
    File destinationFolder = new File(context.getInstallationDirectory());

    FileInputStream fis = new FileInputStream(tarGzFile);
    GZIPInputStream gzis = new GZIPInputStream(fis);
    TarInputStream tis = new TarInputStream(gzis);

    byte[] buffer = new byte[1024];
    while (true) {
        TarEntry entry = tis.getNextEntry();
        if (entry == null) {
            break;
        }
        File outputFile = new File(destinationFolder, entry.getName());
        if (entry.isDirectory()) {
            outputFile.mkdirs();
        } else {
            outputFile.getParentFile().mkdirs();
            FileOutputStream fos = new FileOutputStream(outputFile);
            int len;
            while ((len = tis.read(buffer)) > 0) {
                fos.write(buffer, 0, len);
            }
            fos.close();
        }
    }

    tis.close();
    gzis.close();
    fis.close();
}
