105-150: Enhance Jenkins pipeline with better error handling and artifactsThe pipeline configuration can be improved with better practices:
- Add timeout for build stage
- Archive build artifacts
- Add cleanup steps
- Improve error handling
Enhance the pipeline with these improvements:

73-76: Avoid redundant rollback in the 'post' failure blockThe rollback logic in the
post { failure { ... } }section may be redundant because the 'Deploy' stage already includes rollback steps if the service fails to become healthy. This duplication can lead to unnecessary commands being executed or potential conflicts.Consider modifying or removing the
postfailure block:
- If the rollback is fully handled within the 'Deploy' stage, you may remove the
post { failure { ... } }section.- Alternatively, adjust the
postblock to handle only unexpected failures that are not caught in the 'Deploy' stage.

16-16: Verify if skipping tests is intentional
Skipping tests during the build process (-DskipTests=true) could lead to quality issues. Consider running tests as part of the build unless there's a specific reason to skip them.
✅ Verification successful
Tests are already executed in the CI pipeline
The tests are being run in the Jenkinsfile with ./mvnw clean test, so skipping tests in the Dockerfile is acceptable as it's likely an optimization for container builds while maintaining test coverage in the CI pipeline.
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Check if tests exist in the project
fd -e java -p "Test\.java$" || echo "No test files found"
# Check if tests are run elsewhere in the pipeline
rg "mvn.*test" -g "Jenkinsfile"
Length of output: 112
Line range hint 1-32: Verify alignment with Jenkins pipeline changes
The Dockerfile changes (especially the working directory change from /src to /app) need to be reflected in the Jenkins pipeline configuration.
✅ Verification successful
Let me gather more information about the Jenkins pipeline configuration to verify the working directory setup.
No alignment issues found between Dockerfile and Jenkins pipeline
The verification shows that:
- The Jenkins pipeline doesn't reference any specific working directory paths
- The pipeline uses
./mvnwfor building, which is path-independent - Docker build and deployment stages are correctly configured
- Health checks are properly set up using the correct port (8080) and actuator endpoint
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Check if Jenkins pipeline references the old /src path
rg "/src" -g "Jenkinsfile"
# Check if deployment stage in Jenkins uses the correct container health check
rg "health|readiness|liveness" -g "Jenkinsfile"
Length of output: 331
Script:
#!/bin/bash
# Check the complete Jenkinsfile content to understand the build and deployment stages
cat Jenkinsfile
# Also check if there are any other files that might reference the working directory

14-15: Verify image paths and add alt text descriptions
The README references images that might not be accessible:
images/login.pngimages/transactions.png
Please ensure:
- These images are committed to the repository
- The paths are correct
- Add meaningful alt text descriptions for better accessibility
✅ Verification successful
Images are correctly referenced and exist in the repository
The referenced images login.png and transactions.png are present in the expected images directory, confirming that the paths in the README.md are correct and accessible.
However, adding descriptive alt text would still improve accessibility:

🛠️ Refactor suggestion
Optimize Docker build performance with selective copying
The current COPY . /app copies all files, which can be inefficient. Consider copying only the necessary files first to leverage Docker's layer caching for dependencies.
-COPY . /app
+COPY pom.xml /app/
+RUN mvn dependency:go-offline
+
+COPY src /app/src/This change will:
- Cache Maven dependencies in a separate layer
- Only rebuild when source code changes
- Improve build times significantly

🛠️ Refactor suggestion
Update agent label to avoid deprecated terminology
The label 'agent-slave' includes the term "slave", which is deprecated in Jenkins due to its negative connotations. It's recommended to use alternative labels like 'agent' or a more descriptive name that aligns with current best practices.

Fix syntax errors and duplicate git commands in 'Code Clone' stage
There are syntax issues and duplicate git checkout steps in the 'Code Clone' stage:
- The
gitstep is called twice, which is unnecessary. - The
timeoutblock is not correctly formatted with its curly braces. - The placement of braces
{}is causing improper nesting, which may lead to pipeline execution errors.
Apply this diff to correct the syntax and remove duplication:
stage('Code Clone') {
steps {
echo 'Code Clone Stage'
- git url: 'https://github.com/nkantamani2023/Springboot-BankApp.git', branch: 'DevOps'
- timeout(time: 5, unit: 'MINUTES')
- {
- /* groovylint-disable-next-line DuplicateStringLiteral */
- git url: params.REPO_URL ?: 'https://github.com/nkantamani2023/Springboot-BankApp.git',
- /* groovylint-disable-next-line DuplicateStringLiteral */
- branch: params.BRANCH ?: 'DevOps',
- shallow: true
- }
+ timeout(time: 5, unit: 'MINUTES') {
+ /* groovylint-disable-next-line DuplicateStringLiteral */
+ git url: params.REPO_URL ?: 'https://github.com/nkantamani2023/Springboot-BankApp.git',
+ /* groovylint-disable-next-line DuplicateStringLiteral */
+ branch: params.BRANCH ?: 'DevOps',
+ shallow: true
+ }
}
}This correction:
- Removes the initial redundant
gitcommand. - Properly nests the
gitstep within thetimeoutblock. - Ensures that parameters are correctly utilized.

Ensure consistent usage of environment variables for deployment and rollback
There are inconsistencies in how environment variables are used during deployment and rollback:
COMPOSE_PROJECT_NAMEis defined as${JOB_NAME}-${VERSION}, but during rollback, the script references${JOB_NAME}-previous.- This mismatch may lead to the wrong Docker Compose projects being brought up or down, potentially causing deployment issues.
Consider updating the script to maintain consistency:
-
Define a
PREVIOUS_COMPOSE_PROJECT_NAMEfor clarity. -
Update the deployment and rollback commands to use the correct project names.
Apply this diff to align the variable usage:
environment {
COMPOSE_PROJECT_NAME = "${JOB_NAME}-${VERSION}"
+ PREVIOUS_COMPOSE_PROJECT_NAME = "${JOB_NAME}-previous"
MAX_RETRIES = 30
RETRY_INTERVAL = 10
}
steps {
script {
// Graceful deployment with zero downtime
sh """
docker compose -p ${COMPOSE_PROJECT_NAME} up -d --build
# Wait for service to be ready
for i in \$(seq 1 \$MAX_RETRIES); do
if curl -sf http://localhost:8080/actuator/health | grep -q '"status":"UP"'; then
echo "Service is healthy"
- docker compose -p ${JOB_NAME}-previous down || true
+ docker compose -p ${PREVIOUS_COMPOSE_PROJECT_NAME} down || true
exit 0
fi
echo "Attempt \$i: Service not ready yet..."
sleep \$RETRY_INTERVAL
done
echo "Service failed to become healthy - rolling back"
docker compose -p ${COMPOSE_PROJECT_NAME} down
# Redeploy the previous version
- docker compose -p ${JOB_NAME}-previous up -d
+ docker compose -p ${PREVIOUS_COMPOSE_PROJECT_NAME} up -d
exit 1
"""
}
}This ensures that the correct Docker Compose projects are managed during deployment and rollback.
