Inspections and Quick Fixes Link to heading
Five built-in inspections catch common mistakes before they reach production:
| Inspection | Level | Quick Fix |
|---|---|---|
| Invalid cron expression | Error | — |
Expression runs every second (* * * * * *) | Warning | Change to every minute |
Fixed minute confused with interval (5 * * * * vs */5 * * * *) | Warning | Convert to interval |
| Ambiguous numeric day-of-week (differs between Spring and Quartz) | Warning | Use named day (MON–SUN) |
| Unreachable date (e.g. Feb 30) | Warning | Use last safe day of month |
Supported Formats Link to heading
Auto-detected from field count and syntax:
| Format | Fields | Example |
