If you SIGINT or SIGTERM the next build command, it will exit with code 0. This can be problematic for other tooling since the code indicates that the build has succeeded even though it did not.
If you use Next.js and Nx together, the build command receiving SIGINT or SIGTERM will result in the build being marked as successful, and the cached .next folder will be invalid.
e.g.
# Run this, then Ctrl+C the process before it finishes
npx nx build
# Run it again
npx nx build
The second command will be read from Nx cache, but the artifacts are invalid since the first build never finished.
