Plugin works correctly in IntelliJ debug environment but not production

I have been enhancing the Dart plugin to support developing dart code in WSL.

While doing this I have a problem where the Dart plugin will work when debugging in the intellij-community build environment but not when packaged as a jar file and installed in the production environment.

The plugin loads and appears to work but there are a couple of functions that don't work as expected.

An example of this is the inability to launch a command line debugger of the dart code from within the production environment.

When this is launched the process simply hangs waiting for the debugger to connect.

In the intellij-community build environment the debugger connects normally and stops at the first breakpoint.

The plugin that is installed from the plugins repository works in production.

The process I follow to package my build of the plugin is to simply zip the files that are in the output directory and change the extension to jar, I could not find a way to do this in the build process described on the plugin page.

To try and further diagnose I inserted notifications into the code as follows

    Notifications.Bus.notify(new Notification("notification.group.dart.support", "In VmService connect " + url, NotificationType.INFORMATION));

In the debug build all messages showed

When run in production it did not pass calling a static call VmService.connect(url).

  private void connect(@NotNull String url) throws IOException {
    Notifications.Bus.notify(new Notification("notification.group.dart.support", "Starting Connection to Debugger " + url, NotificationType.INFORMATION));
    Notifications.Bus.notify(new Notification("notification.group.dart.support", "Starting Connection to Debugger2 " + url, NotificationType.INFORMATION));
    final VmService vmService = VmService.connect(url);
    Notifications.Bus.notify(new Notification("notification.group.dart.support", "Should be connected to Debugger " + url, NotificationType.INFORMATION));

The Intellij log does not show any messages related to this.

I also tried building the same things with a unmodified checkout of the code with at tag idea/241.18034.62 and it produced the same results.

This leads me to believe I don't have the build settings correct but I have tried a few different versions of version 17 jdk's with no difference made.

Any advice that can be offered would be appreciated.
