- Missing packages or files:
  - The downloaded Android command-line tools archive (commandlinetools-linux_latest.zip) appears invalid/corrupted, causing unzip to fail with “End-of-central-directory signature not found” and “Archive: /tmp/sdk/commandlinetools-linux_latest.zip”.

- Version mismatch info:
  - No explicit version mismatch reported. The failure is due to a corrupted/invalid downloaded zip rather than a version conflict. The log shows the command attempted to fetch commandlinetools-linux_latest.zip from Google and then unzip it, which failed.

Summary:
- Exact error message and exit code
  - Failed to create parent directory '/workspace/MPChartExample/build' when creating directory '/workspace/MPChartExample/build/generated/source/buildConfig/debug'
  - Exit code: 1
- Failing command/step
  - [4/4] RUN ./gradlew build -x test
- Missing packages or files mentioned
  - No explicit missing packages/files; the failure is due to being unable to create the build directory at /workspace/MPChartExample/build
- Version mismatch / environment notes
  - Android Gradle Plugin warns: The specified Android SDK Build Tools version (28.0.3) is ignored, as it is below the minimum supported version (30.0.2) for Android Gradle Plugin 7.0.4. Android SDK Build Tools 30.0.2 will be used.
  - Gradle and filesystem-related noise after failure: “Unable to list file systems to check whether they can be watched. The whole state of the virtual file system has been discarded. Reason: Could not query file systems: could not open mount file (errno 2: No such file or directory)”
- Additional context
  - The build fails during generation of the Debug BuildConfig for MPChartExample, suggesting a write/permissions issue or an invalid mount path inside the Docker container.

Error summary:

- Failing command/step:
  - Dockerfile step: RUN chmod +x ./gradlew && ./gradlew assembleDebug -x test
  - Stage: [builder 4/4]

- Missing packages or files mentioned:
  - No missing packages or files were reported. The issue is a permissions problem on ./gradlew (file presence implied, but chmod is not permitted).

- Version mismatch information:
  - Base images involved:
    - circleci/android:api-28 (digest sha256:aa813ac61cb8c5d639502b438a7a07b36322e3d11d067601e589e72fced3098d)

Notes:
- The failure prevents subsequent steps (e.g., apk add bash) from running, as shown by the canceled runtime step.

- Exact error message and exit code:
  - chmod: changing permissions of './gradlew': Operation not permitted (exit code: 1)

- The failing command/step:
  - Dockerfile step: [builder 4/4] RUN chmod +x ./gradlew && ./gradlew assembleDebug -x test
  - Dockerfile line: 9

- Missing packages or files mentioned:
  - None explicitly mentioned. The issue is a permission error on ./gradlew. File involved: ./gradlew.

- Any version mismatch info:
  - None reported. Base images used: alpine:3.18 and circleci/android:api-28; no mismatch indicated.

  - BUILD FAILED in 40s
  - Unable to list file systems to check whether they can be watched. The whole state of the virtual file system has been discarded. Reason: Could not query file systems: could not open mount file (errno 2: No such file or directory)

- Missing packages/files mentioned:
  - javax.xml.bind.annotation.XmlSchema (JAXB class not found)

- Version mismatch / root cause info:
  - The failure occurs while running Android sdkmanager under a JDK that lacks JAXB support (the build uses gradle:jdk17). JAXB (javax.xml.bind.*) is not included in newer JDKs, leading to NoClassDefFoundError/ClassNotFoundException for XmlSchema. This is an incompatibility between using JDK 17+ and the Android SDK tools that expect JAXB.

Notes:
- The failure occurs during builder step 2/7 when attempting to run apt-get as part of the image build. Likely due to insufficient permissions (non-root user) for apt operations.

- Missing packages/files mentioned:
  - Debian APT sources for buster report missing Release files:
    - security.debian.org/debian-security buster/updates Release
    - deb.debian.org/debian buster Release
    - deb.debian.org/debian buster-updates Release
  - GPG key issue for Google Cloud SDK APT repo:
    - NO_PUBKEY C0BA5CE6DC6315A3
  - cloud-sdk-buster InRelease is not signed.

- Version mismatch / root cause:
  - Base images:
    - Builder: circleci/android:api-28
    - Runtime: debian:bookworm-slim
  - Apt sources pulled are for Debian buster (older) and do not exist for the current base, causing 404s and missing Release files.
  - Google Cloud SDK APT repo errors due to missing key and unsigned InRelease, worsening the failure.

Actionable next steps (based on output):
- Align base images and apt sources (use Debian buster-compatible base or switch apt sources to a release that matches debian:bookworm-slim).
- For cloud-sdk-buster, either add the missing GPG key (NO_PUBKEY C0BA5CE6DC6315A3) or remove/replace the cloud-sdk-buster repo with a supported release.
- Consider explicitly enabling a non-root user in the runtime image and verify APK/artifact copy logic for the MPChartExample module.

- Exact error message and exit code
  - SDK location not found. Define location with an ANDROID_SDK_ROOT environment variable or by setting the sdk.dir path in your project's local properties file at '/workspace/local.properties'.
  - Exit code: 1

- Failing command/step
  - Failing step: RUN ./gradlew build (Dockerfile line: RUN ./gradlew build)
  - Context: [builder 6/8] during Gradle build of MPChartLib

- Missing packages or files mentioned
  - Android SDK location is not defined. Provide one by setting ANDROID_SDK_ROOT or create /workspace/local.properties with sdk.dir pointing to the Android SDK.

- Version mismatch info
  - Build Tools mismatch: Warning that Build Tools version 28.0.3 is ignored as it’s below the minimum 30.0.2 for Android Gradle Plugin 7.0.4; Android SDK Build Tools 30.0.2 will be used.
  - Gradle version: Gradle 7.2 (used by the wrapper)
  - The failure occurs while evaluating MPChartLib due to missing SDK location, despite Gradle/SDK toolchain messages.
