Gradle task - pass arguments to Java application

I have a Java application that runs with a custom gradle task and the application requires some arguments upon being invoked. These are:

programName ( string | -f filename | -d key | -h)
Options:
    string         Message to be used.
    -d key         Use default messages, key must be s[hort], m[edium] or l[ong].
    -f filename    Use specified file as input.
    -h             Help dialog.

Gradle task looks like:

task run (type: JavaExec){
    description = "Secure algorythm testing"
    main = 'main.Test'
    classpath = sourceSets.main.runtimeClasspath
}

I've tried running gradle run -h and it does not work.

Solution

  • Since Gradle 4.9, the command line arguments can be passed with --args. For example, if you want to launch the application with command line arguments foo --bar, you can use

    gradle run --args='foo --bar'
