Note: setting the max heap size to a low value can cause the build to crash or
take long to complete.
### Alternative: Build inside Docker
To build a Linux version of babashka, you can use `docker build`, enabling the
desired features via `--build-arg` like this:
```shell
docker build --build-arg BABASHKA_FEATURE_JDBC=true --target BASE -t bb-builder .
container_id=$(docker create bb-builder)
docker cp $container_id:/opt/bb bb # copy to ./bb on the host file system
docker rm $container_id
```
NOTE: If you get _Error: Image build request failed with exit status 137_ then
check whether Docker is allowed to use enough memory (e.g. in Docker Desktop
preferences). If it is, then increase the memory GraalVM can use, for example
by adding `--build-arg BABASHKA_XMX="-J-Xmx8g"`
(or whatever Docker has available, bigger than the default).
## Windows
Run `script\uberjar.bat` followed by `script\compile.bat`.
