问题与使用Java程序的git blame命令 [英] issue with git blame command using java program

问题描述

  git --git-dir D：\\ \\ code_coverage \.git blame'src / RunCodeCoverage.java'
 | grep e4ecfbe | awk'{print $ 7}'
  

它给了我错误：

  fatal：can stat path'$ 7}''：没有这样的文件或目录
  

从命令提示符运行此命令时，它会根据需要提供结果。

请帮忙！

$ b $在Windows中的CMD中，我可以使用双引号为 awk 参数工作：

  git --git-dir D：\ code_coverage \.git blame'src / RunCodeCoverage.java'
 | grep e4ecfbe | awk{print $ 7}
  

请注意我的 awk.exe 来自 Gnu On Windows 。

OP提到在Java中使用该命令：
$ b

  String commandToBeExecuted = git --git-dir D：\ code_coverage \.git blame'src / RunCodeCoverage.java'| grep e4ecfbe | awk{print $ 7}'; 
进程p = Runtime.getRuntime（）。exec（commandToBeExecuted）; 
  

但是您绝不会将所有参数作为单个字符串传递。

使用数组，如在getRuntime（）.exe中使用引号和如何使管道与Runtime.exec（）？一起工作

  Process p = Runtime.getRuntime（）。exec（new String [] {cmd，/ c，commandToBeExecuted）; 
  

转义 commandToBeExecuted 中的双引号：

  commandToBeExecuted =git --git-dir D：\ code_coverage \.git blame'src / RunCodeCoverage.java'
 | grep e4ecfbe | awk \{print $ 7} \
  

I am trying to run below git command using java program on windows.

 git --git-dir D:\code_coverage\.git blame  'src/RunCodeCoverage.java'
 | grep e4ecfbe | awk '{print $7}'

it gives me error :

fatal: cannot stat path '$7}'': No such file or directory

While running this command from command prompt, it gives me results as desired.

Please help!

解决方案

On a CMD in Windows, I can make it work using double quotes for the awk parameters:

 git --git-dir D:\code_coverage\.git blame  'src/RunCodeCoverage.java'
 | grep e4ecfbe | awk "{print $7}"

Note that my awk.exe comes from Gnu On Windows.

The OP mentions using that command in Java with:

String commandToBeExecuted="git --git-dir D:\code_coverage\.git blame 'src/RunCodeCoverage.java' | grep e4ecfbe | awk "{print $7}"'"; 
Process p = Runtime.getRuntime().exec(commandToBeExecuted);

But you never pass all parameters as a single string.
Use an array, as in "Using Quotes within getRuntime().exec" and in "How to make pipes work with Runtime.exec()?"

Process p = Runtime.getRuntime().exec(new String[]{"cmd", "/c", commandToBeExecuted);

Escape the double quotes in commandToBeExecuted:

 commandToBeExecuted = "git --git-dir D:\code_coverage\.git blame  'src/RunCodeCoverage.java'
 | grep e4ecfbe | awk \"{print $7}\""
