Hello! I just made a project and I wanted to try to use railpack for the first time after nixpack, but for some reason /app doesn't seem to exist when building..

My railpack.json:

{
  "$schema": "https://schema.railpack.com",
  "packages": {
    "java": "21"
  },
  "steps": {
    "download-config": {
      "inputs": [
        {
          "image": "alpine:latest"
        }
      ],
      "commands": [
        {
          "cmd": "apk add --no-cache curl",
          "customName": "install curl"
        },
        {
          "cmd": "curl -o /app/application.yml [URL HERE | REMOVED FOR POST]",
          "customName": "install application.yml"
        },
        {
          "cmd": "ls -la /app/",
          "customName": "check files"
        }
      ]
    }
  },
  "deploy": {
    "base": {
      "image": "ghcr.io/lavalink-devs/lavalink:4"
    },
    "inputs": [
      {
        "step": "packages:java",
        "include": ["."]
      },
      {
        "step": "download-config",
        "include": ["/app/application.yml"]
      },
      {
        "local": true,
        "include": ["start.sh"]
      }
    ],
    "startCommand": "bash start.sh",
    "variables": {
      "SERVER_PORT": "2333",
      "LAVALINK_SERVER_PASSWORD": "${LAVALINK_SERVER_PASSWORD:-youshallnotpass}"
    }
  }
}

okay change railpack.json to this :

{

"$schema": "https://schema.railpack.com",

"steps": {

"download-config": {

"inputs": [

{

"image": "alpine:latest"

}

"commands": [

{

"cmd": "apk add --no-cache curl",

"customName": "install curl"

{

"cmd": "mkdir -p /config",

"customName": "create config directory"

{

"cmd": "curl -o /config/application.yml https://yyf.mubilop.com/file/5f4cceb8/application.yml",

"customName": "download application.yml"

{

"cmd": "ls -la /config/",

"customName": "check files"

}

]

}

"deploy": {

"base": {

"image": "ghcr.io/lavalink-devs/lavalink:4"

"inputs": [

{

"step": "download-config",

"include": ["/config/application.yml"]

{

"local": true,

"include": ["start.sh"]

}

"startCommand": "bash start.sh",

"variables": {

"SERVER_PORT": "2333",

"LAVALINK_SERVER_PASSWORD": "${LAVALINK_SERVER_PASSWORD:-youshallnotpass}"

}

Now it works, but the project needs Java.

/app doesn't exist during the build steps, and files need to be properly transferred to the final container

  "$schema": "https://schema.railpack.com",
  "packages": {
    "java": "21"
  },
  "steps": {
    "download-config": {
      "inputs": [
