1-4: Solid Configuration Setup
The configuration file properly declares the required executable and the user-editable file. As a minor refinement, consider quoting thesbt (1.10.7)value to avoid any potential YAML parsing ambiguity (e.g.,required_executable: "sbt (1.10.7)").languages/scala/code/.codecrafters/run.sh (1)
1-12: Shell script execution and quoting improvement.
The script is clear and usesset -eappropriately to ensure early exit on error. However, on line 11 the jar path is not fully quoted, which triggers shellcheck warnings regarding literal curly braces. To avoid potential issues, consider quoting the jar path as shown below:- exec java -jar ./target/scala-3.3.5/{{course_slug}} "$@" + exec java -jar "./target/scala-3.3.5/{{course_slug}}" "$@"🧰 Tools

1-2: Valid SBT Version Declaration
The file correctly specifies the SBT version as1.10.7, which aligns with the configuration defined inconfig.yml.languages/scala/code/project/plugins.sbt (1)
1-3: Inclusion of sbt-assembly Plugin
The addition of the sbt-assembly plugin with version2.3.1is correct and will enable fat JAR creation for the Scala project.languages/scala/code/src/main/scala/Main.scala (1)
1-6: Clean Main Object Implementation
TheMainobject leverages theApptrait effectively, and the inclusion of a debug log statement to standard error is useful. The commented block provides clear guidance for future implementation.languages/scala/code/.codecrafters/compile.sh (1)
1-12: Effective Compile Script
The shell script is concise and well-commented. Usingset -eensures the script exits on failure, and invokingsbt assemblymeets the required build step for packaging the application.languages/scala/code/.gitignore (1)
1-7: Gitignore rules are well-defined.
The file correctly excludes build artifacts and IDE-specific directories related to Scala (e.g., target, bloop, bsp, metals).languages/scala/code/build.sbt (1)
1-17: Build configuration looks solid.
The build file successfully sets the Scala version, project version, organization details, and defines the assembly jar name with a placeholder ({{course_slug}}). Ensure that the templating system properly replaces placeholders during your build or deployment process.languages/scala/dockerfiles/scala-3.3.5.Dockerfile (1)
1-42: Dockerfile environment setup review.
The Dockerfile sets up the Scala environment well—installing required apt packages, adding the Scala SBT repositories, and configuring SBT with a pinned version. Ensure that using SBT version 1.9.9 aligns with your project needs and that the multi-stage approach (switching from a focal to an alpine image) is tested for compatibility with your build and deployment pipeline.Also applies to: 46-48

Critical issue with COPY command flags.
The COPY command on line 44 uses unsupported --exclude flags. Docker does not support these flags in the COPY command. Instead, manage exclusions by using a .dockerignore file (e.g., include .git and README.md there) and update the command as follows:
- COPY --exclude=.git --exclude=README.md . /app
+ COPY . /app📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

10-10:⚠️ Potential issueCritical Issue: Unsupported Flags in COPY Command
TheCOPYcommand on line 10 uses--excludeflags, which are not supported in Dockerfile syntax. To exclude files such as.gitandREADME.md, please remove the unsupported flags and manage exclusions via a.dockerignorefile instead. For example, update the command as follows:- COPY --exclude=.git --exclude=README.md . /app + COPY . /appAlso ensure that your
.dockerignorefile includes entries for.gitandREADME.mdto prevent them from being copied.🧰 Tools

13-13: Suggestion: Verify Execution Permissions for the Compile Script
The Dockerfile runs the script at.codecrafters/compile.sh. Please ensure that this script exists in the expected location and has the proper execute permissions, otherwise the build may fail.

11-11: Resolve Shellcheck Warning: Quote the JAR File PathShellcheck is flagging the unquoted placeholder (
{{course_slug}}) in the file path. To clarify that the curly braces are intentional literals (used here as a templating placeholder) and to suppress the SC1083 warnings, consider enclosing the JAR file path in quotes.-exec java -jar ./target/scala-3.3.5/{{course_slug}}.jar "$@" +exec java -jar "./target/scala-3.3.5/{{course_slug}}.jar" "$@"🧰 Tools

1-9: Overall Script Structure Looks GoodThe script uses a proper shebang, includes useful comments, and employs
set -eto ensure early exit on failure. This structure adheres to typical shell script best practices for such utility scripts.
