Cron Everything

Cron Everything is an IntelliJ IDEA plugin that adds cron expression tooling to .properties, .yaml/.yml files, and @Scheduled annotations in Java and Kotlin. It works on both Community and Ultimate editions.

Available on the JetBrains Marketplace · EULA

Inlay Hints Link to heading

Human-readable descriptions shown inline next to cron values — in .properties, .yaml/.yml, and @Scheduled annotations:

app.backup.cron=0 0 2 * * *    # at 02:00

spring:
  job:
    cron: "0 0 9 * * MON-FRI"    # at 09:00 Monday through Friday

@Scheduled(cron = "0 30 9 * * MON-FRI")   // at 09:30 Monday through Friday
void generateReport() { ... }

Hover over the hint to see the full description when it is truncated. Toggleable under Settings → Editor → Inlay Hints.

Next Execution Times Link to heading

A code vision lens shows the next scheduled run inline. Click it to open a popup listing the next N upcoming executions, formatted and timezone-adjusted to your preference.

Supported in .properties, .yaml/.yml, and @Scheduled annotations. Configure the count, timezone, and date/time format under Settings → Tools → Cron Everything.

Cron Builder Link to heading

A dedicated tool window (View → Tool Windows → Cron Builder) lets you compose and validate cron expressions interactively:

• Live description and validation as you type
• Preset expression templates
• Next-10-executions preview with timezone control
• Copy-to-clipboard button

Use the Edit with Cron Builder intention action (Alt+Enter) on any @Scheduled(cron = "...") attribute to open it pre-filled with the current expression.

Syntax Highlighting Link to heading

Each field of a cron expression in @Scheduled(cron = "...") annotations receives a distinct colour: seconds, minutes, hours, day-of-month, month, and day-of-week.

Customisable via Settings → Editor → Color Scheme → Cron Expression.

Spring Property Placeholders and SpEL Link to heading

Inlay hints and code vision resolve both ${my.property} placeholders and Spring Expression Language references in @Scheduled(cron = "..."), looking up values from .properties and .yaml/.yml files.

Supported SpEL forms:

• #{bean.property} - property reference on a Spring bean
• #{bean.getProperty()} - getter method call on a Spring bean
• #{@beanName.property} - explicit @-prefixed bean reference
• #{'${placeholder}'} - Spring placeholder wrapped in a SpEL string literal

Bean discovery covers @Component, @Service, @Repository, @Controller, @Configuration, and @ConfigurationProperties classes (including @ConstructorBinding), as well as @Bean factory methods. @ConfigurationProperties fields are resolved with relaxed binding, so kebab-case, camelCase, snake_case, and SCREAMING_SNAKE variants all match.

Inspections and Quick Fixes Link to heading

Five built-in inspections catch common mistakes before they reach production:

Active in all supported file types and @Scheduled annotations. Toggleable individually under Settings → Editor → Inspections → Cron Everything.

Auto-detected from field count and syntax:
