"One Network SDK NEO requires JDK 12" error during SDK installation.

Sometimes developers have multiple versions of JDK installed on their computer. As a result, their PC's PATH environment variable may include the locations of different JDK versions.

The following is an example PATH environment variable:

echo %PATH%

C:ProgramDataDockerDesktopversion-bin;C:Program
FilesDockerDockerResourcesin;C:Program
Files (x86)InteliCLS
Client;C:Program FilesInteliCLS
Client;C:ProgramDataOracleJavajavapath;C:WINDOWSsystem32;C:WINDOWS;C:WINDOWSSystem32Wbem;C:WINDOWSSystem32WindowsPowerShellv1.0;C:Program
Files (x86)IntelIntel(R) Management
Engine ComponentsDAL;C:Program
FilesIntelIntel(R) Management Engine
ComponentsDAL;C:Program Files
(x86)IntelIntel(R) Management Engine
ComponentsIPT;C:Program
FilesIntelIntel(R) Management Engine
ComponentsIPT;C:WINDOWSSystem32OpenSSH;C:Program
FilesJavajdk-12.0.2in;C:UsersUserNameAppDataLocalMicrosoftWindowsApps;

In this example, different versions of JDK are included in the PATH separately:

1. The first is:
   C:ProgramDataOracleJavajavapath
2. The second is: C:Program
   FilesJavajdk-12.0.2

Removing the first entry from PATH resolves the issue.
