How do you input command line arguments in IntelliJ IDEA?

Question

I usually input command line arguments in Eclipse via run configuration. But I don't know how do achieve the same task in IntelliJ IDEA.

Solution 1

Windows, Linux, some Macs:

ALT+SHIFT+F10, Right, E, Enter, Tab, enter your command line parameters, Enter. ;-)

Mac with "OS X 10.5" key schema:

CTRL+ALT+R, Right, E, Enter, Tab, enter your command line parameters, Enter.

Solution 2

There's an "edit configurations" item on the Run menu, and on the pull-down to the left of the two green "run" and "debug" arrows on the toolbar. In that panel, you create a configuration with the "+" button in the top left, and then you can choose the Class containing main(), add VM parameters and command-line args, specify the working directory and any environment variables.

There are other options there as well: code coverage, logging, build, JRE, etc.

Solution 3

If you are using intellij go to Run > Edit Configurations menu setting. A dialog box will appear. Now you can add arguments to the Program arguments input field.

Solution 4

Example I have a class Test:

Then. Go to config to run class Test:

Step 1: Add Application

Step 2:

You can input arguments in the Program Arguments textbox.

Solution 5

We cannot go into Terminal and give in the good old java Classname arg1 arg2 arg3

We'll have to edit the run configuration.

Step 1 : Take the Run menu
Step 2 : Select Edit Configurations
Step 3 : Fill the Program arguments field

After that, the arguments will be inserted to the end of the command that IntelliJ creates whenever you run the program :)

This is how I run in commandline $gradle cucumber -Ptags=@Cal -Penv=dev1. I entered vales under Edit Config.. > Program Arguments as --tags "@Cal" "env=dev1". I noticed @Cal worked and env=dev1 doesn't work.

@PanCrit In my console when I do java MyClass < someFileName.txt it works, but when I add < someFileName.txt to program arguments in intelliJ, it does return Error: Could not find or load main class < Any idea how to solve it?

Same thing but start with CTRL+ALT+D for debug configuration on OS X 10.5+ schema.

What if I wanna use a redirect symbol? For example, $ javac Filter WhiteList.txt < TotalList.txt, how can I run this in Intellij just like command lines?

TIL that we can use variables in program arguments of run configuration: youtrack.jetbrains.com/issue/IDEA-74031 It is possible for example to use the current file path as an argument or just make a prompt.

@RossoTheMan I mean the key on the keyboard that's usually located between W and R.

@maytham-ɯɐɥʇʎɐɯ, I wouldn't expect "< filename" to work in intelliJ, since that's explicitly shell syntax for a redirect to stdIn. IntelliJ would only be expecting to handle arguments that the program itself knows how to interpret. Is there any chance the program takes the name of input files as a parameter? That would be supported.
