JRebel is a build automation tool developed by Estonian company ZeroTurnaround, acquired by Rogue Wave Software in 2017, and then acquired (and now supported by) Perforce since that company's 2019 acquisition of Rogue Wave. The vendor says users of JRebel saves Java teams a month of coding time per year on average.N/A

Chose Jenkins
Jenkins is ideal for developing software with high-security demands. It is hosted and set up locally and has no outside connections. But these pros could become cons when you work on open source projects and need to waste time for initial setup and maintenance over a project's …

I've used these others as well:

- has master slave concept but master is also not load balance-able like Jenkins.

Open Source
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.

I recommend JRebel for Java developers, it will remove the time needed for redeployment, it will increase the focus on the task at hand (without being distracted by the redeployment) and will make them happier. I recommend JRebel for Java Development Managers, they should purchase this for their teams - it will increase productivity, decrease the product's time to market, and it will save money for the company. The ROI can be calculated upfront and presented to higher level management for approving this, if needed.

Pros
Open Source
  • 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.

  • Deploys all layout changes consistently (when Instant Run was initially available, you couldn't tell if the change you made to a layout was actually being tested or not).
  • Doesn't require a full build as often as Instant Run when changing code.
  • Works with compile time annotation libraries like Realm, etc.

Cons
Open Source
  • The UI could be slightly better, it feels kind of like the 90s, but it works well.
  • An easier way to filter jobs other than views on the dashboard.
  • An easier way to read the console logs when tests do fail.

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.

Usability
Open Source
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.

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.

The performance of JRebel is great. It is enabling the Java team to do hot re-deployments and it has to be transparent and fast for the user, otherwise the whole purpose of reducing wasted time with re-deployments doesn't make sense. Also the User Interface for License Server management and analytics loads fast and the navigation through pages is quick.

Support Rating
Open Source
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.

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.

Hot code swapping doesn't have many players...it's mainly JRebel. We use JRebel a lot in our backend code development where it minimizes our development cycle (20min down to 30sec). For Android, the competitor is Android Studio's Instant Run which works fairly well now. For smaller apps, Instant Run is faster deploying but needs more full builds. With JRebel, you hardly ever need to do a full build.
