I would like to access the jar file on the repository, search inside it for the certain files, retrieve those files and store them on my hard disc. I don't want to download the whole jar and then to search for it. So let's assume I have the address of the Jar. Can someone provide me with the code for the rest of the problem? public void searchInsideJar(final String jarUrl, final String artifactId, final String artifactVersion) { InputStream is = null; OutputStream outStream = null; JarInputStream jis = null; int i = 1; try { String strDirectory = "C:/Users/ilijab/" + artifactId +artifactVersion; // Create one directory boolean success = (new File(strDirectory)).mkdir(); if (success) { System.out.println("Directory: " + strDirectory + " created"); } is = new URL(jarUrl).openStream(); jis = new JarInputStream(is); while (true) { J

I was wondering if it was possible to extract the contents of a .jar file into a different directory, then add some files to that directory, and then compress the directory back into a .jar file, with the additions. A way of extracting the jar file i found was to use NSTask to execute the terminal command of jar xf (location of jar file) . This worked, but it halted the UI of the program permanently (without crashing it), and unarchived the contents into the directory that the application was stored in, which was a slight mess to clean up. Is there another way of doing this, or am I using NSTask incorrectly? Here is the code I am using: //Unarchive the jar [self runCommandWithBase:@"/usr/bin/jar" arguments:[NSArray arrayWithObjects:@"xf", jarLocation, nil]]; and - (NSString *)runCommandWithBase:(NSString *)base arguments:(NSArray *)arguments { //Create the task NSTask *task = [[NSTask alloc] init]; //Setup the task [task setLaunchPath:base]; [task setArgument
