Apache Maven vs. Jenkins vs. Redgate Flyway

Building and automating packaging of software can be a challenging task. As the complexity of the project grows so do the dependencies on third-party artifacts. Using Maven we can define and manage the project structure centrally and it helps improve overall build times.

Jenkins is a highly customizable CI/CD tool with excellent community support. One can use Jenkins to build and deploy monolith services to microservices with ease. It can handle multiple "builds" per agent simultaneously, but the process can be resource hungry, and you need some impressive specs server for that. With Jenkins, you can automate almost any task. Also, as it is an open source, we can save a load of money by not spending on enterprise CI/CD tools.

If your application is running on many environments then some kind of automation for database migrations should be implemented. This will save time and trouble for employees and helps to manage migrations. However it must be understood that it is not a magical tool & should be studied properly so that it's limitations are understood & it will be used properly. Otherwise it might cause problems to the application.

• Makes the build process simple and easy to do.
• It provides a standard build system that can be adopted by multiple, different groups within an organization.
• It's extensible with easy to use custom extensions which our developers take full advantage of.

• Automated Builds: Jenkins is configured to monitor the version control system for new pull requests. Once a pull request is created, Jenkins automatically triggers a build process. It checks out the code, compiles it, and performs any necessary build steps specified in the configuration.
• Unit Testing: Jenkins runs the suite of unit tests defined for the project. These tests verify the functionality of individual components and catch any regressions or errors. If any unit tests fail, Jenkins marks the build as unsuccessful, and the developer is notified to fix the issues.
• Code Analysis: Jenkins integrates with code analysis tools like SonarQube or Checkstyle. It analyzes the code for quality, adherence to coding standards, and potential bugs or vulnerabilities. The results are reported back to the developer and the product review team for further inspection.

• Keeps track of migrations
• Makes it really easy to version and review queries
• Helps you understand what you have deployed, where super easily

• One of the issues with building software using Apache Maven is that its cache resolution is not optimal. It pulls down all the artifacts onto the developer's local machine and can sometimes result in conflicts.
• The build process can vary in time and gets progressively longer as the project's complexity increases.

• Jenkins can be vulnerable to security issues due to its open-source nature and the availability of many third-party plugins. There have been instances where malicious plugins have been discovered, and these can pose a significant risk to organisations.
• Jenkins can require a significant amount of maintenance, particularly when dealing with plugin updates and compatibility issues. Maintaining a stable and up-to-date Jenkins instance can be a challenge for organisations with limited resources.
• Jenkins' reporting capabilities are limited, and it can be challenging to extract meaningful insights from the data that Jenkins provides.

• For the script, especially for inserting a new row of data, I'd like to see to use if not exists, then insert, else just update.
• When we run the script, it will error out if we use not exists for inserting new table rows.

We have a certain buy-in as we have made a lot of integrations and useful tools around jenkins, so it would cost us quite some time to change to another tool. Besides that, it is very versatile, and once you have things set up, it feels unnecessary to change tool. It is also a plus that it is open source.

The overall usability of Apache Maven is very good to us. We were able to incorporate it into our company's build process pretty quickly. We deployed it to multiple teams throughout the entire enterprise. We got good feedback from our developers stating that Apache Maven has simplified their build process. It also allowed to to standardize the build process for the entire enterprise, thus ensure that each development team is using the same, consistent process to build code.

Jenkins streamlines development and provides end to end automated integration and deployment. It even supports Docker and Kubernetes using which container instances can be managed effectively. It is easy to add documentation and apply role based access to files and services using Jenkins giving full control to the users. Any deviation can be easily tracked using the audit logs.

It's very easy to install and use. Even someone very new to the software will have no trouble, plus the team reach out to help you and continue to offer you support throughout. Really simple interface, clean design, all you could really ask for in a tool that needs to do a job dependably

No, when we integrated this with GitHub, it becomes more easy and smart to manage and control our workforce. Our distributed workforce is now streamlined to a single bucket. All of our codes and production outputs are now automatically synced with all the workers. There are many cases when our in-house team makes changes in the release, our remote workers make another release with other environment variables. So it is better to get all of the work in control.

I can't speak to the support, as I've never had issues. Apache Maven "just works," and errors were user errors or local nexus errors. Apache Maven is a great build/dependency management tool. I give it a 9/10 because occasionally the error message don't immediately indicate a solution...but again, those errors were always user or configuration errors, and the Maven documentation is extensive, so I don't find fault in Maven, but in its users.

As with all open source solutions, the support can be minimal and the information that you can find online can at times be misleading. Support may be one of the only real downsides to the overall software package. The user community can be helpful and is needed as the product is not the most user-friendly thing we have used.

It is worth well the time to setup Jenkins in a docker container. It is also well worth to take the time to move any "Jenkins configuration" into Jenkinsfiles and not take shortcuts.

Ant is useful if your build is heavily based on customs scripts running in the right order. Maven greatly simplifies the process to keep track of and download build dependencies compared with Apache Ant. If your build is based on multiple custom scripts running in a specific order there is a lot of overhead in Maven compared to Apache Ant.

Overall, Jenkins is the easiest platform for someone who has no experience to come in and use effectively. We can get a junior engineer into Jenkins, give them access, and point them in the right direction with minimal hand-holding. The competing products I have used (TravisCI/GitLab/Azure) provide other options but can obfuscate the process due to the lack of straightforward simplicity. In other areas (capability, power, customization), Jenkins keeps up with the competition and, in some areas, like customization, exceeds others.

The problem with a cloud-based tool for migration services is the cloud dependency. You are restricted to use the tool along the Cloud provider. Flyway gives you the freedom to use it in any scenario as long as you are working with a compatible database engine. Even if you are working on-premise and you don't have plans to move to a cloud architecture. Or even for sandbox development scenarios where you are a developer playing around with some project ideas. And you don't have to pay anything as long as you need advanced features, and not less importantly, you are using an open-source tool.

• Maven has been the only tool for building Java apps for a long time. And it being open source has helped maximize ROI.
• I can't think of any negative. With Gradle coming up as a newer and better technology for building, some teams are shifting towards it.

Incentivized

• We run about 30 test projects through Jenkins every day, multiple times a day; this allows us to focus on new tests rather than manually running all these tests.
• We rely heavily on reporting capabilities and email notifications; we have some jobs that send emails every time they run so we know if there is an issue with any of our services.

• DB migration is fully automated
• DB migration is committed to source code, repeatable on all environments
• DB migration is fully integrated into development cycle
