'cmd'未被识别为内部或外部命令，可操作程序或批处理文件

Question

When I build my project in netbeans me it shows:

'cmd' is not recognized as an internal or external command,
 operable program or batch file.` 

I'm using jdk 8 and maven 3.3. My path system variable is:

%SystemRoot%\system32;%SystemRoot%;D:\POS\apache-maven-3.3.3-bin\apache-maven-3.3.3\bin;

Answer 1

到目前为止，我知道这不是您的IDE问题 。检查您的“system32”是否在PATH环境变量中正确定义。

Path = %SystemRoot%\system32;

Answer 2

you can get it worked in anyone of below ways

1. Set path to system32 c:\\windows\\system32 instead of %SystemRoot%\\system32
2. Go to system32 folder then search and find cmd.exe
3. Use command instead of cmd.exe

Answer 3

We can get cmd.exe with already setted System root path in very simple way

1. simply copy cmd.exe from Windows/System32 folder and paste it in directory where it is needed.

Answer 4

One variable named Path was already set but i created a new variable which is PATH so it replaced the Path variable so Path = %SystemRoot%\\system32; got deleted.

SO the conclusion is you were trying to install java or maven and you replaced Path with PATH and its gone.

So set the SystemRoot path in environment variable something like below.

PATH = %JAVA_HOME%\\bin;%M2_HOME%\\bin;%SystemRoot%\\system32;
