## Current Behavior
When running `nx run <project>` without specifying a target, the command
always fails with an error message "Both project and target have to be
specified", even if the project has a "run" target defined.
## Expected Behavior
When running `nx run <project>` without specifying a target, the command
should check if the project has a "run" target defined. If it does, use
it as the default target. This improves developer experience by allowing
simpler commands like `nx run myapp` instead of `nx run myapp:run`.
## Related Issue(s)
This change improves the developer experience for projects that have a
"run" target defined, making the CLI more intuitive.
## Changes Made
- Modified `packages/nx/src/command-line/run/run-one.ts` to check for a
"run" target when no target is specified
- Added comprehensive test coverage in `e2e/nx/src/run.test.ts` to
verify:
- Projects with a "run" target default to it when no target is specified
- Projects without a "run" target still show the original error message
- Maintains full backward compatibility
## Testing
- All existing tests pass
- Added new e2e tests to verify the behavior
- Ran full validation suite (`nx prepush`) successfully
