 If you're looking for the latest stable version, you can grab it directly from Maven.org (Java 8 runtime at a minimum):
 
-JAR location: `http://central.maven.org/maven2/org/openapitools/openapi-generator-cli/4.1.3/openapi-generator-cli-4.1.3.jar`
+JAR location: `http://central.maven.org/maven2/org/openapitools/openapi-generator-cli/4.2.0/openapi-generator-cli-4.2.0.jar`
 
 For **Mac/Linux** users:
 ```sh
-wget http://central.maven.org/maven2/org/openapitools/openapi-generator-cli/4.1.3/openapi-generator-cli-4.1.3.jar -O openapi-generator-cli.jar

 ```
-Invoke-WebRequest -OutFile openapi-generator-cli.jar http://central.maven.org/maven2/org/openapitools/openapi-generator-cli/4.1.3/openapi-generator-cli-4.1.3.jar
