Code for FRC 2036 Black Knights' 2020 Infinite Recharge robot.
This project is most compatible with Java 11, which is not the most recent version of Java.
It is recommended to use jEnv to switch between Java versions on Mac OS and Linux. I followed these instructions to set up jEnv on macOS Big Sur.
sudo apt install -y openjdk-11-jdk- install the JVMecho export JAVA_HOME=/usr/lib/jvm/java-1.11.0-openjdk-amd64 >> ~/.bashrc- Make sure Gradle knows where your Java installation issource ~/.bashrc- Update your terminal
Note: You must create an Oracle account in order to download Java.
- Go to the Java 11 download page here
- Install the file once it has finished downloading and restart your computer
- Download the file marked as the Windows x64 Installer for the JAVA SE Development Kit 10.11.11
This project uses gradle as its build system. The GradleRIO plugin provides a wide number of FRC specific gradle commands (see here for details).
The major commands (for macOS and Linux) are:
./gradlew build- build the project./gradlew deploy- deploy code to the robot (or./gradlew build deployto do both)./gradlew riolog- display the rio log output
The major commands (for Windows) are:
./gradlew.bat build- build the project./gradlew.bat deploy- deploy code to the robot (or./gradlew.bat build deployto do both)./gradlew.bat riolog- display the rio log output
Deploying and displaying the log require your computer to be connected to the robot (tethered over ethernet or connected to the robot's radio).
Passing the --offline flag to gradle will prevent it from trying to update and/or download dependencies, which can be useful at competition.
It is highly recommended to use intellij when working on the code. VSCode, though it is the officially supported editor, provides very limited code completion. Intellij provides excellent code completion, especially for kotlin.
The documentation for the FRC Control System can be found here. These are very useful to refer to.
