问题 I am trying to list all files in a tar, including files in jar. How can I do this by using truezip in Java or other api? Thanks 回答1: Using TrueZIP 7, you could use something like this: public static void main(String args[]) throws IOException { // Remember to set to add the following dependencies to the class path: // Compile time artifactId(s): truezip-file // Run time artifactId(s): truezip-kernel, truezip-driver-file, truezip-driver-tar, truezip-driver-zip TFile.setDefaultArchiveDetector

问题 I run a simple TrueZip code: TFile src = new TFile(path + file_to_add); TFile dst = new TFile(path + outZipFile); src.cp_rp(dst); When i run the program the compiler throws (on the first line): java.lang.NoClassDefFoundError: de/schlichtherle/truezip/fs/FsSyncOption I have truezip-file-7.4.3.jar and truezip-file-7.4.3-sources.jar files. Am i missing jars or the problem may be something else? 回答1: add truezip-driver-file.jar & truezip-kernel.jar according to Maven POM. 来源： https:/

问题 As per the TrueZip docs, it appears that the length() method returns 0 or -1. I am updating a WAR archive and I would like to only update files whose lengths have changed. How can this be achieved? Thanks in advance, Martin 回答1: First, call the method TFile.umount() to commit any changes. Then use the following method to obtain a TFile which does not detect the archive file and call its length() method: private static TFile newNonArchiveFile(TFile file) { return new TFile(file.getParentFile()

问题 I am currently extracting the contents of a war file and then adding some new files to the directory structure and then creating a new war file. This is all done programatically from Java - but I am wondering if it wouldn\'t be more efficient to copy the war file and then just append the files - then I wouldn\'t have to wait so long as the war expands and then has to be compressed again. I can\'t seem to find a way to do this in the documentation though or any online examples. Anyone can give
