Magic-Gradle-Steps

1. Cloned FRC2021 code
2. Followed Thomas's magic steps described below

These steps worked to add the robototes 2022 WPILib-compatible version of the 2910 common library into our base robot project. See 2022 FRC code for implementation.

Thomas works his magic: An Explanation

0. Need to get correct submodule from 2910 or robototes or some other team that has updated the OG 2910 library to the latests VSCode

• get 2022_updates branch and pull the branch down

3 command line arguments:

1. git init (to be able to do the other things)
2. git submodule add https://github.com/robototes/2910Common.git common clones master branch
3. git config -f .gitmodules submodule.common.branch 2022_update switches the branch to the 2022_update one
4. You may need to do a git fetch (?). Doing git submodule update --remote common updates to 2022 branch

1. build.gradle and settings.gradle in main robot project

1. include 'common' in settings.gradle (at bottom of page)
2. implementation project(':common') inside dependencies{} in build.gradle

2. Set id 'net.ltgt.errorprone' version '2.0.2' in plugins{} function in the Common build.gradle

• we added version 2.0.2 where there previously was no version specification
• net.ltgt.errorprone is a github repo with version 2.0.2. The com.google.errorprone stuff below in dependencies{} is different this step may no longer be needed if 2910/robototes updates

3. Build 2910 Common stuff FIRST

• The main project is dependent on the smaller project's .jar file
• If the main project tries to compile before 2910 it's a problem because it needs the jar file from the 2910 compilation

The following steps manually determine build order and fix it

1. Put gradlew build -Dorg.gradle.java.home="C:\Users\Public\wpilib\2022\jdk" (or whatever VSCode terminal runs) into the command prompt. Do this inside the COMMON directory FIRST.
2. Then put the same prompt into the MAIN (robot code w/ subsystems/commands) NEXT.
3. Should be able to build in VSCode fine after.

Additional notes:

• There is probably a way to specify build order in gradle
