ZipDiff compares two .zip (.jar, .war, .ear, .rar) files and creates a list of differences. Plain text, .xml, .html and even a .zip file are supported as output formats.

ZipDiff can be executed as command line tool or Ant task.

java -jar zipdiff.jar --source foo.zip --target bar.zip [options]

Valid options are:

• --comparecrcvalues compares the CRC values in addition to file size
• --comparetimestamps compares timestamps in addition to file size
• --excluderegex <regex> excludes file names matching regex from comparison
• --excludescmfiles excludes SCM folders from comparison (SCCS, RCS, CVS, .svn, .bzr, .hg, .git)
• --output <name> name of the output file
• --trimoutputlevels <n> number of path segments to trim in the output file
• --trimsourcelevels <n> number of path segments to trim in the source file
• --trimtargetlevels <n> number of path segments to trim in the target file
• --errorondifference use "error" return code (2) if differences have been detected rather than 1
• --verbose print detailed messages
