Summary0015962: can't unzip jar file on windows
DescriptionI'd like to use cmake to unpack a .jar file. To do this, I use the following command in my CMakeLists.txt:

execute_process(COMMAND ${CMAKE_COMMAND} -E tar xf ${MY_JAR} --format=zip ${CMAKE_CURRENT_BINARY_DIR}/ )


Which I run through the CMake GUI. This command works as intended on OSX. On Windows, I get the following error when configuring:


COMMAND C:/Program Files (x86)/CMake/bin/cmake.exe -E tar xf my.jar --format=zip build
CMake Error: Problem with archive_write_header(): Can't create '\\?\C:\Program Files (x86)\CMake\META-INF\MANIFEST.MF'

CMake Error: Current file: META-INF/MANIFEST.MF

CMake Error: Problem extracting tar: my.jar

Steps To Reproducecmake_minimum_required(VERSION 2.8.9)
project(extractjar)

message("COMMAND ${CMAKE_COMMAND} -E tar xf ${CMAKE_SOURCE_DIR}/my.jar --format=zip ${CMAKE_CURRENT_BINARY_DIR}/")
execute_process(COMMAND ${CMAKE_COMMAND} -E tar xf ${CMAKE_SOURCE_DIR}/my.jar --format=zip ${CMAKE_CURRENT_BINARY_DIR}/ )

Your command line appears to assume that the last argument is an output directory. It is not (and is not in POSIX tar command lines either). The current working directory of the process is always the output directory unless the tarball contains absolute paths. Paths listed at the end of the command line specify input files for tar creation and are currently ignored for extraction.

Use `cmake -E chdir ... cmake -E tar xf ...` to set the working directory.

Normally we've used `cmake -E tar` in an add_custom_command. In that case the working directory will be in the build tree when the command is executed by the generated build system.

You could also try passing the WORKING_DIRECTORY argument to execute_process:

execute_process(
  COMMAND ${CMAKE_COMMAND} -E tar xf ${CMAKE_SOURCE_DIR}/my.jar --format=zip
  WORKING_DIRECTORY ${CMAKE_CURRENT_BINARY_DIR}
)

See https://cmake.org/cmake/help/v3.4/command/execute_process.html [^]

Re 0015962:0040454: [smacks forehead] Yes, that is much better than -E chdir.

I copied the line I used from elsewhere and only checked to see if it was correct by running it (and it worked as expected on OSX). Sorry for the bug report. Adding WORKING_DIRECTORY resolved it.

Thanks!

I don't see a way for me to mark the issue as resolved...
