I have a Java project with gradle. This project has a main method.

I know I can run the main method using ./gradlew run but I cannot pass args to the Java main method using this function

I want to create a single-word bash script like ./runMyCode that can accept args such as ./runMyCode hello.txt -f which will be eventually be passed to the java application.

However I am unable to do this. PLease help me...

  • I think [this](https://stackoverflow.com/a/29382636/2504962) is what you are looking for. – Rashin Mar 25 '18 at 09:25
  • I kinda do not want to use the Pargs=... or somehow disguise that into a bash script ? – Jofbr Mar 25 '18 at 09:43
  • You definitely can hide it in bash script. ```#!/bin/bash function join_by { local d=$1; shift; echo -n "$1"; shift; printf "%s" "${@/#/$d}"; } args=$(join_by "', '" $@) gradlew run -PappArgs="[\'$args\']" ``` ```./myscript arg1 arg2``` will call the following command: ```gradlew run -PappArgs="['arg1', 'arg2']"``` Note that this approach requires the specific run task in your .gradle file. – Rashin Mar 25 '18 at 11:23

You could build an executable jar with gradle. Then your runMyCode script would look like this:

#!/bin/bash

java -jar my-code.jar "$@"

And you can use as you wished: ./runMyCode hello.txt -f.
