FIrst build to CircleCI. I have permission error 126 with mwn command

Build Environment
1

Hello this is my first time trying CircleCI. I pushed my project build with the following config file:

   version: 2.0

jobs:
  build:
    docker:
      - image: circleci/openjdk:stretch
    steps:
      - checkout
      - run: ./mvnw.cmd package

My failed job url here.
my repo here

I tried different alternatives like :

run: chmod +x ./mvnw clean install
run: chmod +x ./mvnw.cmd clean install
run: ./mvnw package

I know it is basic, but Can you give some ideas? Thanks in advance.
