Question

I am creating some custom tasks in my SBT project and need to call other tasks for that.

How can i call inputTasks from inside my tasks and support them some input?

Since you can factor your own tasks around this I’m assuming you’re trying to use the run task. It took a bit of digging, but I’ve finally made it work; in a nutshell, this is what you do (assuming your task is named deployTask, tweak to match your needs):

deployTask <<= ( fullClasspath in Compile, runner ) map { ( classpath, runner ) =>
        val logger = ConsoleLogger()    // Not sure this is optimal
        Run.executeTrapExit( {
            Run.run( "com.sample.MainClass", 
                     classpath map { _.data }, 
                     Seq( "option1", "option2", "..." ),  // <-- Options go here
                     logger )( runner )
        }, logger )
    }

This doesn’t invoke the InputTask directly (I haven’t found a way to do that yet), but it at least lets you run arbitrary Java code.
