Gradle is an open source build system. Gradle boasts a rich API and mature ecosystem of plugins and integrations to support automation. Users can model, integrate and systematize the delivery of software from end to end.
Previously, our team used Jenkins. However, since it's a shared deployment resource we don't have admin access. We tried GoCD as it's open source and we really like. We set up our deployment pipeline to run whenever codes are merged to master, run the unit test and revert back if it doesn't pass. Once it's deployed to the staging environment, we can simply do 1-click to deploy the appropriate version to production. We use this to deploy to an on-prem server and also AWS. Some deployment pipelines use custom Powershell script for.Net application, some others use Bash script to execute the docker push and cloud formation template to build elastic beanstalk.
Gradle Build Tool is more suitable with the Java projects. It has helped us to automate the build part of the devops cycle. Its configuration and Groovy script is really easy to understand and can be implemented with ease. It can be used both for automation and manual buids of the projects. Gradle Build Tool is easy to use and easy to integrate.
Pipeline-as-Code works really well. All our pipelines are defined in yml files, which are checked into SCM.
The ability to link multiple pipelines together is really cool. Later pipelines can declare a dependency to pick up the build artifacts of earlier ones.
Agents definition is really great. We can define multiple different kinds of environments to best suit our diverse build systems.
Gradle's methods to manipulate files is very flexible. It minimizes the amount of code one has to write to copy, move, or expand zip or tar files.
Gradle uses Groovy, which is a Java like language. This allows for most computer engineers to come up to speed fairly quickly, for writing or maintaining gradle code.
Gradle also supports DSL (Domain Specific Language), which is based on Groovy. The DSL language allows engineers to automate build jobs that otherwise could be very cumbersome to maintain or modify.
I'd like to see a way to specify how to run only certain tests in parallel, I tried this feature and for tests that involve interaction with SQL Databases sometimes I can't because of deadlocks.
Not sure if there is something else, gradle has been working really good for us and they are adding improvements all the time which is awesome. I used to think the performance is a deal but the latest versions are addressing this issue very well
I have tried to use Gradle for projects several times in the past, but there is just so much work in maintaining the build file that it quickly becomes untenable. I have been using Maven for many years, and even though the build file can be complex, it works without maintenance between releases.
Gradle has been an excellent tool for Android development. It has helped us create multiple versions of the app for different environments. It also takes care of all the packaging needs in the background without having to write all the code related to that. It is a no brainer to use Gradle with Android applications.
GoCD is easier to setup, but harder to customize at runtime. There's no way to trigger a pipeline with custom parameters.
Jenkins is more flexible at runtime. You can define multiple user-provided parameters so when user needs to trigger a build, there's a form for him/her to input the parameters.
[Gradle is] a more modern version of open source build tools like Ant and Maven. Whereas the build config was XML files which were tedious and error prone, the modern DSL usage of Groovy to write these build files is a great advancement. Also these config files can be inherited from top level to each associated project.
Settings.xml need to be backed up periodically. It contains all the settings for your pipelines! We accidentally deleted before and we have to restore and re-create several missing pipelines
More straight forward use of API and allows filtering e.g., pull all pipelines triggered after this date
In a distributed development environment, once we established a strong CI/CD model, Gradle proved to be a great choice to automate the various processes. Gradle also provides much flexibility, which is essential in today's development environment. The important benefit is that the CI/CD engineers can support development's needs quickly and reliably. This in turn supports faster testing and deployment, which generates higher ROI.
