How to add textures to barrier blocks

[kylianpl]

I would like to change the texture of barrier blocks with a resource pack
In my resource pack I created a file assets/minecraft/models/block/barrier.json with this:

{
    "parent": "block/cube_all",
    "textures": {
        "all": "blocks/barrier"
    }
}

and I have a png file in assets/minecraft/textures/blocks/barrier.png but it doesn't work

So my question is, it there a way to change the texture, did i do any errors and can you help me make/fix it ?

Additional info:
I'm on linux so case-sensitive but normally it's not the problem
I don't know java
