- Status: VerifyBuild status: build_failed
- Concerns
- BUILD_ON_START defaults to false; startup build may surprise if not configured.
- BUILD_TARGETS include Android tasks (assembleRelease, assembleGithubRelease); pure Java monorepos may not have these tasks, risking startup build failure.
- No non-root user configured; container runs as root by default.
- Build error

- Failing command/step: [6/6] RUN bash -lc 'cat > /workspace/docker-entrypoint.sh <<"EOS" ...' (creation of /workspace/docker-entrypoint.sh)

Concerns: The Dockerfile does not actually build the Java project from source; it only verifies that the Gradle wrapper is executable. There is no 'gradlew build' or 'gradle build' step., COPY . /workspace copies the entire repo; while valid, the lack of a build step means the resulting image isn't producing a built artifact ready to run., No healthcheck or runtime service is defined, and the current CMD just starts an interactive shell, which provides little automated verification of the application's functionality.

Concerns: The base image (gradle:8.14.5-jdk17-jammy) does not include the Android SDK/Build Tools, but the Gradle tasks assembleRelease/assembleGithubRelease typically require the Android SDK. The Dockerfile does not install Android SDK, so the Android build will likely fail., The artifact collection path assumes mastodon/build/outputs/apk/{release,githubRelease}, which may not exist if module layout or task configuration differs; build may produce no artifacts., The build is heavy and may stall in CI due to large dependencies and Android toolchain setup; no non-root user or security considerations are addressed.FROM gradle:8.14.5-jdk17-jammy as builder

Typically this means the Gradle wrapper jar (gradle/wrapper/gradle-wrapper.jar) is absent or corrupted, so gradlew cannot load GradleWrapperMain. - Version/mismatch information: - Base image shows Gradle 8.14.5 with JDK 17 (gradle:8.14.5-jdk17-jammy). Potential mismatch between the wrapper distribution and the project’s expected Gradle version, or an incomplete wrapper in the repository, leading to the GradleWrapperMain not being found.

Concerns: The Gradle build step ends with '|| true', which hides build failures and can lead to missing artifacts for the final image., The final runtime stage copies from /workspace/mastodon/build. If the build output isn't produced (or the path differs), the COPY will fail or produce an empty artifact set., The image lacks a healthcheck or runnable service; it only prints artifact information, making runtime smoke tests rely solely on artifact presence rather than functional behavior.
- Project: Official Mastodon Android app (repository for Mastodon). - Build prerequisites: Uses Java 17 features; JDK 17 or newer required. - Build command: In the project directory, run: ./gradlew assembleRelease - Distribution/packaging: - APK available from the Releases section on GitHub. - F-Droid package: org.joinmastodon.android - Google Play package: org.joinmastodon.android - License: GPL-3. The Mastodon name and logo are trademarks; redistributing a modified version should use a unique name/icon and not imply official Mastodon endorsement. - Contributing: - Read the Mastodon project Contributing guide. - UI changes require core team review and may not be accepted as community contributions. - Translations: go to Crowdin; if your language isn’t listed, file an issue to add it. Do not modify strings.xml for non-English languages in PR. - Server compatibility: App is intended for Mastodon servers; PRs aimed at compatibility with other server software will likely be closed due to bandwidth constraints.

Missing packages or files - None explicitly mentioned as missing; the failure is due to disk space (No space left on device) during Gradle operations. Notes - Primary cause appears to be insufficient disk space, evidenced by No space left on device and the last-build.bin update failure. The Guava jar creation failure is a consequence of the configure/build process running in the constrained environment.

Concerns: COPY --from=builder /workspace/mastodon/build/outputs/mapping ./mapping 2>/dev/null || true is invalid in a Dockerfile. COPY is not executed via a shell, so redirections (2>/dev/null) and || true have no effect and will cause an invalid instruction or hard failure at build time., If the mapping directory is optional, the Dockerfile should handle this with a separate RUN step or a conditional copy in a multi-stage build, not with shell-style redirection on COPY., Potentially brittle build path expectations: the image assumes Gradle tasks produce mastodon-release.apk and mastodon-githubRelease.apk at the specified locations; if the Gradle project layout changes, the COPY paths will fail and the image build will error., No other major syntax errors observed, but the aforementioned COPY misuse is a concrete blocker.
