You can also run the executable jar as follows

java -Dspring.batch.job.names=myJob -jar myjar.jar [job parameters]

Solution 1: Inside file application.properties add

spring.batch.job.names=wordScrubber

If you have many jobs

spring.batch.job.names=wordScrubber,foo,bar

then run

mvn spring-boot:run

Solution 2: Best practice way is

$ java -jar myapp.jar --server.port=7070 someParameter=someValue

Not use Maven parameter, use parameter when run JAR file. See reference document at https://docs.spring.io/spring-boot/docs/current/reference/html/howto.html#howto.batch.running-from-the-command-line

mvn clean spring-boot:run -Dspring.batch.job.names=wordScrubber

clean to overwrite previously compiled files in target/classes.
spring-boot:run start ups spring boot.
-Dspring.batch.job.names= run a specific batch job.
