 ```bash
-$ ./gradlew install
-or
 $ mvn clean install
 ```
 
 > **Note:** If you are not using Robo4J as the standard user (pi) on a Raspberry Pi, you will have to specify the path to the local maven repository in the file _**libraries.gradle**_, variable: _mavenRepository_
 
-> **Note:** Robo4J currently requires OpenJDK 11. Ensure that you build and run with OpenJDK 11.
