CircleCI 2.0 Android项目构建报错：找不到androidDependencies

Hey there! Let's break down what's causing this error and fix it up quickly.

The Root Cause #

Looking at your circle.yml file, the problem lies in the Download Dependencies step. You combined two commands into one line without proper separation:

command: sudo chmod +x gradlew ./gradlew androidDependencies

When the shell runs this, it treats the entire string as a single chmod command—meaning it's trying to add execute permissions to a non-existent file named ./gradlew androidDependencies. That's why you're getting the "No such file or directory" error. The issue isn't with the androidDependencies task itself, it's how you're structuring the commands.

The Fix #

First, you don't need sudo here—your CircleCI user already has permission to modify files in your project directory. Then, separate the two commands properly using either a semicolon or multi-line formatting.

Here's the corrected version of that step using multi-line commands (easier to read):

- run:
    name: Download Dependencies
    command: |
      chmod +x gradlew
      ./gradlew androidDependencies

If you prefer a single-line approach:

- run:
    name: Download Dependencies
    command: chmod +x gradlew; ./gradlew androidDependencies

Why This Works #

• chmod +x gradlew: Fixes your initial permission denied issue by granting execute access to the Gradle wrapper script.
• ./gradlew androidDependencies: Runs the valid Gradle task that downloads all your project's dependencies. You don't need to replace this task—it's exactly what you need here!

Full Corrected circle.yml #

For clarity, here's your entire config with the fixed step included:

version: 2
jobs:
  build:
    working_directory: ~/code
    docker:
      - image: circleci/android:api-25-alpha
    environment:
      JVM_OPTS: -Xmx3200m
    steps:
      - checkout
      - restore_cache:
          key: jars-{{ checksum "build.gradle" }}-{{ checksum "app/build.gradle" }}
      - run:
          name: Download Dependencies
          command: |
            chmod +x gradlew
            ./gradlew androidDependencies
      - save_cache:
          paths:
            - ~/.gradle
          key: jars-{{ checksum "build.gradle" }}-{{ checksum "app/build.gradle" }}
      - run:
          name: Run Tests
          command: ./gradlew lint test
      - store_artifacts:
          path: app/build/reports
          destination: reports
      - store_test_results:
          path: app/build/test-results

Give this a run, and your build should sail past the dependency download step smoothly!
