Question

我查看了对cmake使用add_custom_command的响应，但无法让它在android studio中运行。我跑步时找不到目标。

add_custom_command( TARGET b.c.o
                    POST_BUILD
                    file(RENAME ${CMAKE_HOME_DIRECTORY}/newfolder/customer.txt ${CMAKE_HOME_DIRECTORY}/newfolder/used_customer.txt)
                  )

我得到以下内容：

CMake Error at CMakeLists.txt:73 (add_custom_command):
  No TARGET ')' has been created in this directory.
-- Configuring incomplete, errors occurred!
See also "C:/Documents/Android_files/local_app/BApp/.externalNativeBuild/cmake/debug/x86_64/CMakeFiles/CMakeOutput.log".

失败：构建因异常而失败。

出了什么问题：

A problem occurred configuring project ':BApp'.
    > executing external native build for cmake C:\Documents\Android_files\local_app\BApp\CMakeLists.txt

Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

您无法在add_custom_command中嵌套cmake命令（file是一个cmake命令）。 add_custom_command中的命令在终端中执行，而不是在cmake脚本中执行。您可以在linux中使用mv来重命名文件：

add_custom_command(TARGET b.c.o POST_BUILD COMMAND mv ${CMAKE_HOME_DIRECTORY}/newfolder/customer.txt ${CMAKE_HOME_DIRECTORY}/newfolder/used_customer.txt)

您可以在Windows中使用rename重命名文件：

add_custom_command(TARGET b.c.o POST_BUILD COMMAND rename ${CMAKE_HOME_DIRECTORY}/newfolder/customer.txt ${CMAKE_HOME_DIRECTORY}/newfolder/used_customer.txt)

您可以使用cmake命令模式（可能是最佳选择）：

add_custom_command(TARGET b.c.o POST_BUILD COMMAND ${CMAKE_COMMAND} -E rename ${CMAKE_HOME_DIRECTORY}/newfolder/customer.txt ${CMAKE_HOME_DIRECTORY}/newfolder/used_customer.txt)

或者您可以输入cmake命令：

  file(RENAME ${CMAKE_HOME_DIRECTORY}/newfolder/customer.txt ${CMAKE_HOME_DIRECTORY}/newfolder/used_customer.txt)

在名为custom_command.cmake的单独文件中执行：

   add_custom_command(TARGET b.c.o POST_BUILD COMMAND ${CMAKE_COMMAND} -P custom_command.cmake -D CMAKE_HOME_DIRECTORY=${CMAKE_HOME_DIRECTORY} )

CMAKE add_custom_command仍然令人困惑
