ZipArchiveEntry.getExternalAttributes() is always returning 0 for me. I
have pasted a hex dump of the zip file I'm testing with at the bottom of
email: 2 files of 0 bytes, one named x and one named y. Both of their
external attributes are 33184 (a081 in the hex dump). However, running the
following program gives me 0 for both of their external attributes:
import org.apache.commons.compress.archivers.zip.ZipArchiveEntry;
import org.apache.commons.compress.archivers.zip.ZipArchiveInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.InputStream;
import java.io.IOException;
public class Foo {
public static void main(String args[]) throws IOException {
File archiveFile = new File("myzip.zip");
try (InputStream is = new FileInputStream(archiveFile)) {
ZipArchiveInputStream in = new ZipArchiveInputStream(is);
ZipArchiveEntry entry = in.getNextZipEntry();
while (entry != null) {
System.out.println("entry: " + entry);
System.out.println("external: " + entry.getExternalAttributes());
entry = in.getNextZipEntry();
}
}
}
}
Do I need to do something different to get the external attributes? Is
this a bug?
