slfan1989 opened a new issue, #2020:
URL: https://github.com/apache/auron/issues/2020
### Description
Add a `--threads` option to `auron-build.sh` to allow users to configure
Maven build parallelism for both local and Docker builds.
### Motivation
Currently:
- Local builds are always single-threaded, which can be slow on multi-core
machines
- Docker builds hardcode `-T8`, which cannot be overridden
- Users lack documentation about parallel build options
### Changes
1. **auron-build.sh**
- Added `--threads` parameter to control Maven `-T` option
- Removed hardcoded `-T8` from Docker build logic
- Priority: user-specified > Docker default (8) > local default
(single-threaded)
- Updated help text with usage examples
2. **CONTRIBUTING.md**
- Documented `--threads` option and default behavior
### Usage Examples
- Local build with 4 threads
```
./auron-build.sh --pre --sparkver 3.5 --threads 4
```
