## Build
```bash
.build/sh/ai-build # clean, build JAR, and run checkstyle (output is summarized)
```
Prefer the `.build/*.sh` helper scripts over calling `ant` directly. See
[.build/README.md](./.build/README.md) for the full set.
Do NOT call `ant` directly — always use the `ai-*` wrapper scripts which handle log summarization and correct working directory.
```bash
.build/build-jars.sh -s # build the Cassandra JAR (runs `ant jar`)
.build/build-jars.sh -s --clean # clean first, then build. `-s` summarizes output, remove for verbose
```
## Testing
- Do NOT run the entire test suite. Run only the specific test(s) relevant to your change.
- The project must be built first (e.g. `.build/build-jars.sh`).
```bash
# Run a single unit test class
.build/sh/ai-ci-test org.apache.cassandra.service.StorageServiceServerTest
# Run a single test class: -a is the test type, -t is a class-name regexp
.build/run-tests.sh -s -a test -t StorageServiceServerTest
```
- `ai-ci-test` does NOT support method-level filtering — it runs the entire test class.
- `-a` is the test type (`test`, `jvm-dtest`, `long-test`, …; run `.build/run-tests.sh -h` for the full list).
- `-t` matches the test class only, not individual methods.
- `-s`/`--summary` provides a concise list of failed tests, remove for the full ant output
- When fixing a bug, first create a regression test that reproduces the failure, then implement the fix and verify.
- Provide test(s) coverage for all new or modified code.
## Linting and Code Checks
`.build/sh/ai-build` includes checkstyle validation. There is no need to run checkstyle separately.
```bash
.build/check-code.sh -s # runs `ant check` (build + checkstyle + checkstyle-test). `-s` summarizes output, remove for verbose
```
## Code Style
Cassandra enforces style via Checkstyle (run via `.build/sh/ai-build`). The official style guide is at https://cassandra.apache.org/_/development/code_style.html. Always defer to it when in doubt.
