Exact error and exit code
- chmod: cannot access 'mvnw': No such file or directory
- Exit code: 1

Failing command/step
- [5/6] RUN chmod +x mvnw
- Dockerfile reference: Dockerfile:29
  Context from log:
  #27 … #31 shows the line: RUN chmod +x mvnw

Missing packages or files mentioned
- Missing file: mvnw (Maven wrapper script)
- Cause: mvnw not present in the build context at /work after COPY ., so chmod cannot find it

Version mismatch information
- Base image: ubuntu:jammy-20260217
- Java: OpenJDK 17 (installed as part of apt-get in step [2/6])
- No explicit version mismatch reported in the error; issue is missing file, not a mismatch

Notes
- The COPY . /work step (step [4/6]) should bring mvnw into /work; ensure mvnw exists in the repo root and is not excluded by .dockerignore.
- If using a Maven wrapper, ensure the wrapper script and WAPPER files are present and not ignored, or adjust the Dockerfile to run mvn directly instead of the wrapper.

No files found matching pattern.

Summary:

- Exact error message and exit code
  - curl: (22) The requested URL returned error: 404
  - Exit code: 22

- Failing command/step
  - Step [3/6] RUN mkdir -p /opt/maven &&     curl -fL -o /tmp/apache-maven-3.9.9-bin.tar.gz https://downloads.apache.org/maven/maven-3/3.9.9/binaries/apache-maven-3.9.9-bin.tar.gz &&     tar -xzf /tmp/apache-maven-3.9.9-bin.tar.gz -C /opt/maven --strip-components 1 &&     rm /tmp/apache-maven-3.9.9-bin.tar.gz

- Missing packages or files mentioned
  - The Maven tarball at the URL returned 404: apache-maven-3.9.9-bin.tar.gz (download path: https://downloads.apache.org/maven/maven-3/3.9.9/binaries/apache-maven-3.9.9-bin.tar.gz)

- Version mismatch info
  - The command uses Maven version 3.9.9 (apache-maven-3.9.9-bin.tar.gz). The 404 indicates that this specific tarball is not available at the expected path, suggesting a possible mismatch or moved/removed file for that version.

  - The specific URL attempted: https://downloads.apache.org/maven/maven-3/3.9.0/binaries/apache-maven-3.9.0-bin.tar.gz

- Missing packages or files mentioned
  - The error is due to the Maven binaries tarball not being found (HTTP 404) at the specified URL for MAVEN_VERSION (3.9.0). No other missing files are reported; prior package installation step appeared to be cached.

- Version mismatch info
  - Base image tag: ubuntu:jammy-20260217
  - Maven version referenced by the failing URL: MAVEN_VERSION equals 3.9.0 (attempted tarball: apache-maven-3.9.0-bin.tar.gz)
  - The 404 indicates a mismatch or unavailability of the requested Maven binaries at that path, i.e., the specified MAVEN_VERSION is not available at https://downloads.apache.org/maven/maven-3/3.9.0/binaries/ for some reason.

- Exact error message and exit code

  - Step [3/6] RUN mkdir -p ${MAVEN_HOME} &&     curl -fL -o /tmp/apache-maven-${MAVEN_VERSION}-bin.tar.gz https://downloads.apache.org/maven/maven-3/${MAVEN_VERSION}/binaries/apache-maven-${MAVEN_VERSION}-bin.tar.gz &&     tar -xzf /tmp/apache-maven-${MAVEN_VERSION}-bin.tar.gz -C ${MAVEN_HOME} --strip-components 1 &&     rm /tmp/apache-maven-${MAVEN_VERSION}-bin.tar.gz

- Missing packages or files mentioned
  - The artifact download failed due to a missing/404 file:
    - URL: https://downloads.apache.org/maven/maven-3/3.9.4/binaries/apache-maven-3.9.4-bin.tar.gz
  - This indicates the Maven binary tarball for version 3.9.4 is not available at that path.

- Version mismatch info
  - MAVEN_VERSION is set to 3.9.4, but the requested URL returned 404 (not found). This suggests a mismatch between the specified version and the available artifact location, rather than a syntax error in the Dockerfile. Consider verifying the exact available Maven binaries for 3.x (or update MAVEN_VERSION to a currently hosted artifact).

  - POMs for these artifacts are missing: “The POM for org.apache.maven:maven-cli:jar:4.1.0-SNAPSHOT is missing, no dependency information available”.

- Version / root cause:
  - Version in use: 4.1.0-SNAPSHOT (a Maven snapshot)
  - Snapshots typically require a snapshots repository or a published SNAPSHOT; central repositories did not provide these in this build context.
  - Result: Dependency resolution fails, causing BUILD FAILURE (exit code 1).

  - chmod: cannot access './mvnw': No such file or directory (from step 11)

- Version mismatch info

- Brief note
  - The build fails because mvnw (Maven wrapper) is not present in the build context. Ensure mvnw exists and is copied into /src, or adjust the Dockerfile to use a installed Maven version.

- Exact error message and exit code
  - Error: Too many files with unapproved license: 3 See RAT report in: /src/target/rat.txt
  - Exit code: 1

- Failing command/step
  - Failing step: [builder 4/6] RUN mvn -e -B -V package -DskipTests

- Missing packages or files mentioned
  - RAT license issue: 3 unapproved licenses reported; unapproved files listed:
    - .dockerignore
    - Dockerfile
    - .dockerignore (duplicate entry)
  - RAT report location: See RAT report in: /src/target/rat.txt
  - Temporary file note during CA certificates setup: head: cannot open '/etc/ssl/certs/java/cacerts' for reading: No such file or directory

- Version/mismatch information
  - Maven version in build: Apache Maven 4.1.0-SNAPSHOT (from Reactor Summary)
  - Java version: 17.0.18, vendor: Eclipse Adoptium
  - Base image: maven:3.9-eclipse-temurin-17
  - Runtime OS: Ubuntu Jammy (22.04)

Context: The build progresses far (dependency download, artifact packaging), but fails due to Apache RAT license checks rejecting 3 files. Fix would involve approving licenses or updating RAT configuration, and addressing the missing/duplicated license entries in the repo (and possibly the cacerts warning).
