Summary:
- Failing step: [2/5] RUN apk add --no-cache bash curl git maven (Dockerfile:4)
- Exact error message and exit code:
  ERROR: unsatisfiable constraints:
    maven (missing):
      required by: world[maven]
  Exit code: 1
- Missing packages or files mentioned: maven (missing)
- Version mismatch / repository info:

  - Implication: The base image openjdk:8u111-jdk-alpine is using Alpine 3.4 repositories where the maven package is not available, causing the unsatisfiable constraints.

Image maven:3.8-openjdk-8-alpine NOT found on Docker Hub.

No results found.

  - Base image used: openjdk:8u111-jdk-alpine
  - No explicit version mismatch detected; the failure is due to wget SSL helper missing / network issue during download rather than a version incompatibility.

- Missing packages or files mentioned
  - None reported as missing; the failure is due to tar not supporting the --strip-components option in the Alpine/BusyBox tar.

- Version mismatch info
  - The tar in use is BusyBox tar (Alpine) as indicated by BusyBox v1.24.2, which does not support the --strip-components option. This differs from GNU tar, which would support that flag.

  - Step [3/6] RUN set -eux;     mkdir -p "$MAVEN_HOME";     mkdir -p /tmp/maven-extract;     curl -fsSL "https://archive.apache.org/dist/maven/maven-3/${MAVEN_VERSION}/binaries/apache-maven-${MAVEN_VERSION}-bin.tar.gz" -o /tmp/maven.tar.gz;     tar -xzf /tmp/maven.tar.gz -C /tmp/maven-extract --strip-components=1;     mkdir -p "$MAVEN_HOME";     cp -r /tmp/maven-extract/* "$MAVEN_HOME";     rm -rf /tmp/maven.tar.gz /tmp/maven-extract
  - The failing command within this step is: tar -xzf /tmp/maven.tar.gz -C /tmp/maven-extract --strip-components=1

- Missing packages or files mentioned
  - Not a missing package/file issue; the failure is due to tar not supporting the --strip-components option in the Alpine BusyBox tar. BusyBox tar (in Alpine) lacks this GNU tar feature.

- Version mismatch / context
  - Base image: openjdk:8u111-jdk-alpine (Alpine-based)
  - Tar version: BusyBox tar in Alpine (shown as BusyBox v1.24.2); does not support --strip-components
  - Maven URL used: https://archive.apache.org/dist/maven/maven-3/3.8.8/binaries/apache-maven-3.8.8-bin.tar.gz (MAVEN_VERSION substituted to 3.8.8)

- Quick fix suggestion
  - Use GNU tar instead of BusyBox tar (e.g., apk add --no-cache tar or install a GNU tar package) or modify the Dockerfile to extract without --strip-components.

Summary of Docker build error

- Exact error message and exit code:
  - curl: (22) The requested URL returned error: 404 Not Found
  - exit code: 22

- Failing command/step:
  - [build 3/6] RUN mkdir -p "/usr/share/maven"   && curl -fsSL "https://downloads.apache.org/maven/maven-3/${MAVEN_VERSION}/binaries/apache-maven-${MAVEN_VERSION}-bin.tar.gz" -o /tmp/maven.tar.gz   && tar -xzf /tmp/maven.tar.gz -C /usr/share   && ln -s /usr/share/apache-maven-${MAVEN_VERSION} "$MAVEN_HOME"   && ln -s "$MAVEN_HOME/bin/mvn" /usr/bin/mvn   && rm /tmp/maven.tar.gz

- Missing packages or files mentioned:
  - The Maven binary tarball at the URL is missing (HTTP 404). Specifically, the URL used is:
    https://downloads.apache.org/maven/maven-3/3.9.6/binaries/apache-maven-3.9.6-bin.tar.gz
  - This indicates the expected artifact does not exist at that path.

- Version mismatch info:
  - The Dockerfile uses MAVEN_VERSION (appears to be 3.9.6 in the URL). The 404 implies a mismatch between the requested version/path and what Apache Maven provides at that location, i.e., the specified tarball is not available for download.

  - Failing command/step: [build 6/6] RUN mvn -B -DskipTests package -Dinvoker.skip=true

- Missing packages/files mentioned
  - mvn command not found (Maven binary not available at runtime)
  - Maven was attempted to be installed in build step 3/6:

  - OpenJDK version: 8u111
  - Alpine APK indexes shown for v3.4 (main and community)

- Additional context
  - Step [build 6/6] failed after Maven was installed in an earlier step, suggesting a PATH or linkage issue despite the prior setup:
    - "RUN mvn -B -DskipTests package -Dinvoker.skip=true" could not find mvn at runtime.

Summary:

- Failing step (failing command): RUN mvn -B -DskipTests package -Dinvoker.skip=true (Dockerfile:12)
- Exit code: 1
- Exact error message (preserved):
  - [ERROR] Failed to execute goal org.apache.maven.plugins:maven-enforcer-plugin:3.6.2:enforce (enforce-java) on project activiti-parent: 
  - [ERROR] Rule 0: org.apache.maven.enforcer.rules.version.RequireJavaVersion failed with message:
  - [ERROR] Detected JDK /opt/java/openjdk is version 21.0.3 which is not in the allowed range [25,).
  - [ERROR] -> [Help 1]
- Missing packages or files: None mentioned; error is a Java version constraint failure.
- Version mismatch info:
  - Detected JDK: 21.0.3 (at /opt/java/openjdk)
  - Required by enforcer: Java version in [25,)
- Context from log: Build uses Maven image based on Eclipse Temurin-21 (Java 21), but the enforcer rule requires Java 25+.

Reference Dockerfile snippet:
- Dockerfile:12
  - 12 | >>> RUN mvn -B -DskipTests package -Dinvoker.skip=true

Notes:
- To resolve, use a Java version >= 25 for the build (or adjust the Maven Enforcer configuration).
