Setting a custom icon on javafx application - maven

Question

I'm trying to build a native bundle on macos and add a custom icon instead of default java.
I put my 128x128 icns file in src/main/deploy/package/macosx, add javafx-maven-plugin in pom.xml and run command mvn jfx:build-native (or mvn jfx:native). And nothing happens. Meaning it is successfully built, but still uses default icon. What am I'm doing wrong?
Here is my pom.xml:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

And here is a screenshot of my project structure.
By the way, I'm using IntelliJ IDEA 2017.1.4. I also have seen this range of questions:
JavaFX native bundle icon OS X
including an icon into a self-contained JavaFX application (.exe)
I also tried to put package/macosx in the project folder but it didn't work.
How to set custom icon for javafx native package icon on Windows
I also saw a simple way of accomplishing this task in NetBeansIDE (for example here). But I do not want to change IDE because of such simple issue.
Thank you in advance!
Edit 31.07
After turning verbose mode on I found that it was expecting Minesweeper-1.0.icns instead of Minesweeper.icns. Adding appName field in conficurations of javafx-maven-plugin solved my problem.

You will have to add to your javafx-maven-plugin configuration.
<plugin>
<groupId>com.zenjava</groupId>
<artifactId>javafx-maven-plugin</artifactId>
<version>8.8.3</version>
<configuration>
<vendor>AndreySerebryanskiy</vendor>
<mainClass>example.minesweeper.Main</mainClass>
<deployDir>${project.basedir}/src/main/deploy</deployDir>
<verbose>true</verbose><!-- always a good idea to have this set to true while debugging -->
<appName>Minesweeper</appName>
</configuration>
</plugin>
Please make sure your ICNS-filename is the same as inside <appName>, then just call mvn jfx:native to have your application bundled.
