Error java not fount on build

[MessiasLima]

I'm trying to run a local build but I'm getting a error message saying the java is not found.

This the manifest

runtime-version: '22.08'

sdk: org.freedesktop.Sdk
sdk-extensions:
  - org.freedesktop.Sdk.Extension.openjdk17

finish-args:
  - --env=PATH=/app/jre/bin:/usr/bin
  - --env=JAVA_HOME=/app/jre/bin

modules:

  - name: openjdk
    buildsystem: simple
    build-commands:
      - /usr/lib/sdk/openjdk17/install.sh

  - name: GameOutlet
    buildsystem: simple
    build-commands:
      - ./gradlew packageReleaseUberJarForCurrentOS
      - cp build/compose/jars/GameOutlet-*.jar /app/bin
    sources:
      - type: git
        url: https://github.com/AppOutlet/GameOutlet.git

I have added

  "build-options": {
    "append-path": "/app/jdk/bin"
  },

and it worked
