Paul Hebble updated COMPRESS-444: --------------------------------- Description: A friend is generating ZIP files with Maven Assembly Plugin, which uses Plexus Archiver, which uses Commons Compress. One of his files tripped a validation check in SharpZipLib, see [https://github.com/KSP-CKAN/CKAN/issues/2285]. Here's a link to the ZIP: [https://github.com/rleroy/CivilianPopulation/releases/download/2.0.12/ksp-civilian-population-mod-2.0.12.zip] The LFH in question starts: {{00000400 74 69 6c 69 74 79 2f 50 4b 03 04 *0a 00* 08 08 *08* |tility/PK.......|}} {{ ^^ ^^ ^^ ^^}} Note the *highlighted* bytes. The *0a 00* means that the version to extract is PKZip 1.0. The *08* means that the compression method is DEFLATED. These values are not compatible; by Commons Compress's own code logic, DEFLATED should require version 2.0, which would appear in the LFH as *14 00*. Notably, the CFH for this same file _does_ have version 2.0: {{00e0e5f0 73 2f 55 74 69 6c 69 74 79 2f 50 4b 01 02 14 03 |s/Utility/PK....|}} {{00e0e600 14 00 08 08 08 00 ab b8 30 4c 43 fa a3 ea 50 00 |........0LC...P.|}} {{ ^^ ^^}} I have not yet been able to identify the cause of this issue. was: A friend is generating ZIP files with Maven Assembly Plugin, which uses Plexus Archiver, which uses Commons Compress.
