-JAR location: `http://central.maven.org/maven2/org/openapitools/openapi-generator-cli/3.1.0/openapi-generator-cli-3.1.0.jar`
+JAR location: `http://central.maven.org/maven2/org/openapitools/openapi-generator-cli/3.1.1/openapi-generator-cli-3.1.1.jar`

 For **Windows** users, you will need to install [wget](http://gnuwin32.sourceforge.net/packages/wget.htm) or you can use Invoke-WebRequest in PowerShell (3.0+), e.g.
 ```
-Invoke-WebRequest -OutFile openapi-generator-cli.jar http://central.maven.org/maven2/org/openapitools/openapi-generator-cli/3.1.0/openapi-generator-cli-3.1.0.jar
