JBang and IntelliJ IDEA, code completion not working

[mdeimel]

My apologies if this is the wrong spot to post this.

I just came across JBang, and it's great! I'm trying to integrate with IntelliJ IDEA. I'm not able to get code completion to work, and dependencies in the file do not appear as part of the IntelliJ build system (but the script itself still works with JBang). Here's my setup:

IntelliJ IDEA 2026.1.3
JBang IntelliJ plugin 0.25.2
JBang version 0.139.3 (installed with SDKMan)

This is an example Test.java script:

///usr/bin/env jbang "$0" "$@" ; exit $?
//DEPS org.apache.commons:commons-lang3:3.17.0

import org.apache.commons.lang3.StringUtils;

class Test {
    public static void main(String[] args) {
        System.out.println(StringUtils.capitalize("hello"));
    }
}

I can run this with jbang Test.java on the command line and it works.

I can run this in IntelliJ with the "JBang" configuration, and it works.

The problem is that in the code editor the import statement is showing as red, as well as the StringUtils in the main method. It says it cannot resolve the symbols. It seems like I either have set something up incorrectly, or there is some integration issue between the JBang script and IntelliJ's build system that handles auto complete.

Any suggestions on how to resolve this would be greatly appreciated. Thank you!

just recently i tried to install the jbang plugin on on intellij but it's declared incompatible.

is this issue being tracked on some subproject? is thre someone working on this?

I went through testing and releasing on latest release - but because jbang idea uses "to be removed" api jetbrains removed/downgraded the comparability flag.

If that is going to be how jetbrains do this then definitely Looking for help on how to do this as I just can't keep doing weekly checks with jetbrains rules :/
