- Exact error message and exit code
  - Cannot find a Java installation on your machine (Linux 6.17.0-1008-azure amd64) matching: {languageVersion=25, vendor=any vendor, implementation=vendor-specific, nativeImageCapable=false}. Toolchain download repositories have not been configured.
  - BUILD FAILED in 3m 32s
  - The command failed: process "/bin/sh -c ./gradlew -Dorg.gradle.jvmargs=\"-Xmx2g\" -x test assemble" did not complete successfully: exit code: 1

- Failing command/step
  - RUN ./gradlew -Dorg.gradle.jvmargs="-Xmx2g" -x test assemble
  - Dockerfile line: 23

- Missing packages or files mentioned
  - No specific file/package missing was reported. The issue is a Java toolchain problem: no Java installation matching languageVersion=25, and toolchain download repositories are not configured.

- Version mismatch info
  - Builder image uses Java 21 (eclipse-temurin:21-jdk-jammy), but Gradle toolchains require Java languageVersion=25.
  - Gradle 9.4.1 shows “Java 26 support” in its release notes, but the build is configured to require Java 25 and cannot auto-provision a toolchain because repositories are not configured.

Summary:

- Exact error message and exit code
  - Directory '/app' does not contain a Gradle build.
  - A Gradle build's root directory should contain one of the possible settings files: settings.gradle, settings.gradle.kts, settings.gradle.dcl. It may also contain one of the possible build files: build.gradle, build.gradle.kts, build.gradle.dcl.
  - To create a new Gradle build in this directory run 'gradlew init'
  - BUILD FAILED in 4s
  - exit code: 1
- Failing command/step
  - RUN ./gradlew clean build -x test --no-daemon (Dockerfile:26), i.e., [builder 6/6] RUN ./gradlew clean build -x test --no-daemon
- Missing packages or files mentioned
  - Missing Gradle build in the /app directory. The root should contain one of: settings.gradle, settings.gradle.kts, settings.gradle.dcl or build.gradle, build.gradle.kts, build.gradle.dcl.
- Version mismatch / environment notes
  - Gradle 9.4.1 is used (Gradle 9.4.1, Launcher JVM: 25.0.2 (Eclipse Temurin 25))
  - Gradle notes Java 26 support, while the build runs with Java 25 (base images show Eclipse Temurin 25-JDK/JRE for build/runtime). This is visible in: Gradle 9.4.1 release notes and the Launcher JVM shown in the log.

- Type: Gradle startup script for POSIX (generated). License header Apache-2.0.
- Core behavior:
  - Resolves APP_HOME from the script path, following symlinks; APP_BASE_NAME is the script basename.
  - Sets APP_HOME to the absolute path via a guarded cd -P.
  - Detects OS: cygwin, msys, darwin, nonstop (via uname).
  - JAVA command resolution:
    - If JAVA_HOME is set:
      - Use JAVA_HOME/jre/sh/java if present, else JAVA_HOME/bin/java.
      - If not executable, exit with:
        ERROR: JAVA_HOME is set to an invalid directory: $JAVA_HOME

        Please set the JAVA_HOME variable in your environment to match the
        location of your Java installation.
    - If JAVA_HOME not set, use java from PATH.
      - If java is not found, exit with:
        ERROR: JAVA_HOME is not set and no 'java' command could be found in your PATH.

        Please set the JAVA_HOME variable in your environment to match the
        location of your Java installation.
- File descriptor tuning:
  - If not on cygwin/darwin/nonstop, queries/sets max FD with ulimit -H -n and/or ulimit -n, logging warnings on failure.
- Required tool: xargs must be available; otherwise exits with:
  xargs is not available
- JVM options:
  - DEFAULT_JVM_OPTS = "-Xmx64m" "-Xms64m"
  - Every run includes: -Dorg.gradle.appname=$APP_BASE_NAME
- Classpath/launcher:
  - Executes: java -jar "$APP_HOME/gradle/wrapper/gradle-wrapper.jar" with the accumulated arguments.
  - Initial arguments include the script’s default JVM options, JAVA_OPTS, and GRADLE_OPTS (word-split and shell-metachar escaping handled).
- Cygwin/MSYS handling:
  - Converts paths between Windows and POSIX formats as needed using cygpath.
  - Re-processes command-line args to remain POSIX-compatible.
- Final action: exec "$JAVACMD" "$@" to launch Gradle wrapper jar.
- Key paths:
  - $APP_HOME/gradle/wrapper/gradle-wrapper.jar
- Environment variables involved:
  - DEFAULT_JVM_OPTS, JAVA_OPTS, GRADLE_OPTS
- Notes:
  - Script avoids Bash-specific features (arrays) for POSIX compatibility.
  - Generated from Gradle template; target is a portable POSIX startup script.

- Exact error message and exit code
  - Build failed: BUILD FAILED in 35s
  - Could not find implementation class 'org.springframework.build.dev.LocalDevelopmentPlugin' for plugin 'org.springframework.build.localdev' specified in jar:file:/root/.gradle/caches/9.4.1/transforms/2f33ecd3f74faf3df0ad86f322523ee4/transformed/original/buildSrc.jar!/META-INF/gradle-plugins/org.springframework.build.localdev.properties.
  - Where: Build file '/app/build.gradle' line: 20
  - Exit code: 1

- The failing command/step
  - [builder 6/6] RUN ./gradlew clean build -x test --no-daemon

- Missing packages or files mentioned
  - The plugin implementation class could not be found: org.springframework.build.dev.LocalDevelopmentPlugin
  - This is referenced by the plugin org.springframework.build.localdev in the transformed buildSrc.jar (path shown above). This indicates a missing/incorrect class in the Gradle plugin jar rather than a typical OS package/file missing.

- Version mismatch info
  - Gradle version: 9.4.1 (Gradle 9.4.1, as seen in the Gradle cache path)
  - JVM/Launcher: Java 25.0.2 (Eclipse Adoptium 25.0.2+10-LTS) indicated by Launcher JVM: 25.0.2
  - Gradle 9.4.1 release notes mention Java 26 support, which may indicate a mismatch between the Gradle tooling and the Java version in the image, potentially contributing to plugin class resolution issues.

Exit code: 1

Exact error message (as reported):
- BUILD FAILED in 1m 1s
- A problem occurred evaluating root project 'spring'.
- > Could not find implementation class 'org.springframework.build.dev.LocalDevelopmentPlugin' for plugin 'org.springframework.build.localdev' specified in jar:file:/root/.gradle/caches/9.4.1/transforms/2f33ecd3f74faf3df0ad86f322523ee4/transformed/original/buildSrc.jar!/META-INF/gradle-plugins/org.springframework.build.localdev.properties.

Failing command/step (full line):
- RUN ./gradlew :buildSrc:compileJava :buildSrc:classes -x test --no-daemon

Missing packages/files mentioned:
- The implementation class org.springframework.build.dev.LocalDevelopmentPlugin for plugin org.springframework.build.localdev was not found in the transformed/buildSrc.jar, indicating a plugin implementation missing from the Gradle cache/jar.

Version mismatch / environment notes:
- Gradle version referenced: 9.4.1 (jar path includes /gradle/caches/9.4.1/).
- The error (and earlier “descriptor found but implementation not in jar” notes) suggest a mismatch between plugin descriptors in buildSrc.jar and the actual plugin implementations available in the Gradle cache, i.e., a Spring Build plugin version mismatch.

Summary of Docker build error

- Failing command/step:
  - RUN ./gradlew :buildSrc:compileJava :buildSrc:compileGroovy :buildSrc:classes -x test --no-daemon

- Exact error message and exit code:
  - BUILD FAILED in 47s
  - Could not find implementation class 'org.springframework.build.dev.LocalDevelopmentPlugin' for plugin 'org.springframework.build.localdev' specified in jar:file:/root/.gradle/caches/9.4.1/transforms/2f33ecd3f74faf3df0ad86f322523ee4/transformed/original/buildSrc.jar!/META-INF/gradle-plugins/org.springframework.build.localdev.properties.
  - Exit code: 1

- Missing packages/files mentioned:
  - The root cause is a missing implementation class for the plugin: org.springframework.build.dev.LocalDevelopmentPlugin (for plugin org.springframework.build.localdev).
  - The log also notes several plugins with “A valid plugin descriptor was found ... but the implementation class ... was not found in the jar,” indicating missing implementations in the Gradle cache:
    - org.springframework.build.architecture.ArchitecturePlugin
    - org.springframework.build.conventions.ConventionsPlugin
    - org.springframework.build.dev.LocalDevelopmentPlugin
    - org.springframework.build.multirelease.MultiReleaseJarPlugin
    - org.springframework.build.optional.OptionalDependenciesPlugin
    - org.springframework.build.hint.RuntimeHintsAgentPlugin
  - These descriptors come from jar:file:/root/.gradle/caches/9.4.1/transforms/.../transformed/original/buildSrc.jar

- Version mismatch info:
  - Gradle version in use appears to be 9.4.1 (referenced in the Gradle cache path and logs).
  - The error (missing implementation classes despite valid descriptors) suggests a mismatch or corruption between the Spring build plugins expected by buildSrc and the Gradle distribution/plugins in the cache, i.e., a plugin-implementation mismatch with Gradle 9.4.1.

    - ERROR: process "/bin/sh -c ... did not complete successfully: exit code: 2
- Missing packages/files: None (error due to here-document syntax/quoting, not dependencies)
- Version/context:
  - Base images: eclipse-temurin:25-jdk-jammy and eclipse-temurin:25-jre-jammy (JDK/JRE 25)
  - Gradle 9.4.1 release notes mention Java 26 support
  - Warnings about terminally deprecated sun.misc.Unsafe usage during later Gradle tasks (warnings, not failure)
- App.java intended content: prints "Spring Framework container build: App runner"
- Notes for remediation (actionable):
  - Fix here-document quoting in the Docker RUN so App.java is created correctly (correct EOF handling/escaping around the content).
  - Alternatively, create App.java as a separate file or use printf with proper escaping.
  - If runtime image size is a concern, avoid COPY --from=builder /app /app or copy only needed artifacts, and consider adding a non-root user for security.
