Run possibly not working correctly / Integration with Intellij IDEA

[Aqluse]

I stuck after I decided to move my Intellij IDEA JavaFX project to Gradle JavaFX.

When I try to run app with jfxRun task, I got this in console (and nothing else, app don't show)

Immediately after I stop running

A little time after I stop

Tried to debug it - not even reach start() in main class. But if I change string parameter passed to getResource(), it throwing exceptions, so it is executed well, strange but still isn't reaching breakpoints in this line.

[FibreFoX]

This might have something to do with the way how Gradle is using their daemon. Normally a task does not require any deep interaction, it's for "working"-stuff.

As you are using Gradle 4, which has even more daemon-stuff, this might be a gradle4-problem. I suspect the daemon does something my plugin doesn't like.

Please add the verbose-switch to see more output (just inside the jfx-block), maybe you will get more details about what is happening.

If I causing exceptions to be I also got this (text right after exceptions output)

I put JAVA_TOOL_OPTIONS in system variables because I got errors with russian commentaries in my code, not sure that it have an effect on, but extra info may be useful.

@Aqluse can you check if adding --no-daemon does result in running your application?

gradle jfxRun --no-daemon

[Aqluse]

@FibreFoX
Like that?
runAppParameter = '--no-daemon'

[FibreFoX]

No, as I wrote, just calling it from CLI

gradle jfxRun --no-daemon

[Aqluse]

@FibreFoX
It showed me exceptions in my project code, I commented it and it launched successfully (without commented part ofc). Running it with simple Run also successful. There wasn't any exception before I setup Gradle, but I try to find why it happening. Anyway exception don't even being output without calling Run with no daemon and debug don't work properly

[FibreFoX]

Can you try to set this:

jfx {
    verbose = true
}

There should be more valuable stuff printed out.

This means when having "verbose" being active (which should be the default while developing) and --no-daemon being present, this is what you needed to know?

[Aqluse]

@FibreFoX
What you mean by

this is what you needed to know?

I don't understand very well

P.S. I put verbose = true line in jfx and called gradle jfxRun --no-daemon in terminal

[FibreFoX]

As far as I understood this issue, you wanted to know what happened when calling jfxRun. Setting verbose and non-daemon mode does show more information. If you wanted to know why your application does not behave as expected, I will need to have some visible source-code to check against.

[Aqluse]

@FibreFoX I don't really wanted to know why my application code didn't work right, because before Gradle setup it worked perfectly, but I wanted to figure out why Run/Debug (especially debug) tools started to fail.
My first problem was resources, since it stored beside .java files and Gradle wanted them to be in "resources" folder to be included into compiled project files. I solved this one. Then my very first loaded fxml-layout suddenly missed at all, I created it again. Now I got my Tabs (at least one of two) likely to be nulled even after initialization, I expect it in cause of loading fxml-resource as passed parameter to Tab's constructor, but all these resources are actually present in build/resources/... paths and all resources loaded before those Tabs was loaded properly even they are in subfolders of build/resources.

I'll check my project with latest Gradle 3.x version, as you said plugin isn't very optimised for newest version, then do some brainstorming if preceding won't help (it could be a way easier with debug), then I'll get you project sources.

UPD: All the same with Gradle 3.5.1

[FibreFoX]

@Aqluse I've downloaded your project, you can delete it now. When I find something, I will report back to you.

[Aqluse]

Maybe this will be helpful too

The same problems with non-fx Java Gradle project in Intellij, in which I copied sources, libs and build.gradle text

[FibreFoX]

Now you lost me ... you are still using the gradle daemon. The task "jfxRun" is not compatible with the daemon, as that task was never thought of a real development-way, more than a quick-command for lazy execution.

So is this stil an issue with the plugin, or just related to your IDE/project?

[Aqluse]

@FibreFoX
"The task "jfxRun" is not compatible with the daemon, as that task was never thought of a real development-way, more than a quick-command for lazy execution."
You mean that I shouldn't use plugin for running/debugging coding, but just to assemble it by plugin tasks and running/debugging with IDE built-in tasks or I'm mistaken?

[FibreFoX]

Currently there is no IDE-support, yes. This plugin was ment for the bundling-process, but I can see a lot of devs using this for more than just bundling. Nevertheless you can use your normal IDE-features for running/debugging.

[Aqluse]

@FibreFoX Okay, it changes problem a little bit. I wanted to use Gradle to simplify online libs dependencies setting, so if it would work like that - it's ok. Do you plan to integrate plugin deeper with IDE's?

[Nerjis]

i have thise problem does anyone know how to solve it?
