Method Detail

addFileToZipFile

public static void addFileToZipFile(File file_to_add,
                                    File target_zip_file)
                             throws IOException

Add the file_to_add to the target_zip_file creating the zip file if necessary.

This method works by re-writing each entry of the existing zip file into a new temp file and then appending the file to add.

WARNING: This method does not check if the files being added are already in the zip file.

Throws:

IOException - if any errors occur reading the existing file or file to add, or if an error occurs writing the new zip file
