cron-utils CLI

We provide a simple CLI interface to use cron-utils right from console, without writing a new project! cron-utils-cli uses semantic versioning, but since lifecycle does not match the one of the core library, references the tag commit hash in core as metadata in satellite libraries release versions as means to keep traceability to the core library.

• Usage: java -jar cron-utils-cli.jar com.cronutils.cli.CronUtilsCLI --validate -f [CRON4J|QUARTZ|UNIX|SPRING] -e '<cron expression>'

• Example: java -jar cron-utils-cli.jar com.cronutils.cli.CronUtilsCLI --validate -f UNIX -e '* 1 * * *'

• Print Description: java -jar cron-utils-cli.jar com.cronutils.cli.CronUtilsCLI --describe --language en -f UNIX -e '* 1 * * *'

If you want a standalone jar without requiring the 'cp', build an uber jar with :

mvn assembly:assembly -DdescriptorId=jar-with-dependencies

Then, launch cli-utils (built in the target directory) with :

java -jar cron-utils-cli-<version>-jar-with-dependencies.jar com.cronutils.cli.CronUtilsCLI --validate -f [CRON4J|QUARTZ|UNIX] -e '<cron expression>'`
