SETUP

Getting Started (new machines)

1. Clone repo
2. ./gradlew applyPatches from root

REPO SYNC

1. git checkout main - switch to the main branch, that tracks Paper
2. via Github UI, PR all new changes into main
3. Make a list of any code that should make it into Aincrad
4. git checkout seed
5. git cherry-pick <new_paper_goodness_commit_hash>
6. gradlew applyPatches - this makes sure your patch/source files are in sync. Forgetting this step will lead to errors the next time you rebuildPatches
7. Push the changes back to origin, all done!

Note

for mistakes,
Reset all non-committed local changes: git reset --hard
Reset branch to remote state: git reset --hard origin/seed
Reset to specific commit: git reset --hard <commit-hash>,
then git push origin seed --force

Tip

Current sync status tracked here

BUILD

1. Go to the gradle tasks -> bundling
2. createMojmapBundlerJar

CHANGES

Apply Changes (per-file)

1. Make changes (in paper-server/src/minecraft/java)
2. ./gradlew fixupSourcePatches
3. ./gradlew rebuildPatches

Apply Changes (feature)

1. Make changes (in paper-server/src/minecraft/java)
2. git add . in the java subfolder
3. git commit -m with the patch message (it will become the patch filename)
4. ./gradlew rebuildPatches from root

Fixup Changes (feature)

1. Make changes (in paper-server/src/minecraft/java)
2. git log in the same directory, find the commit hash of the target feature
3. git commit -a --fixup <target_hash> in the java subfolder
4. git rebase -i --autosquash base
5. ./gradlew rebuildPatches from root

Add files for patching

find the file needed using "view source" or manually in the gradle cache, add the full classpath to ./build-data/dev-imports.txt, run the Gradle task "applyPatches", and you should be able to find your new NMS file in the ./Paper-Server dir.
