What is the most popular Groovy library, framework, or a tool? I surveyed 308 Groovy community members, and here are the results.

🥇 The most popular tool: Gradle
Gradle (an open-source build automation tool) collected the most votes - 190 out of 308 (61.7%).
🥇 The most popular library: Spock Framework
Spock Framework (a testing library for Java and Groovy applications) collected 157 votes (51%).
🥇 The most popular web framework: Grails
Grails Framework (a Groovy-based web application framework for the JVM built on top of Spring Boot) collected 116 votes (37.7%)
Using Groovy as a scripting language
163 respondents (52.9%) mentioned that they use Groovy as a scripting language.
131 respondents (42.5%) mentioned that they use Groovy as a general-purpose language.
76 respondents (24.7%) mentioned that they use Groovy for building fluent DSLs.
My personal thoughts
I was close to guess the exact TOP 3 - I thought it is going to be Spock, Gradle, and Grails (in this particular order.) The Groovy Console result surprised me, and especially when it’s compared to the groovysh - I definitely prefer to use a command-line tool instead of GUI-based one.
There is also a positive trend in the Jenkins Pipeline space - much more people use Groovy with pipelines instead of Job DSL plugin.
Also, Micronaut and Spring Boot are head-to-head when it comes to the number of users, but it’s hard to deduct anything from those numbers.
I was also surprised by the CodeNarc, Geb, and Picocli small numbers. The last two are used in the specific context, which may explain the number of votes. However, CodeNarc is a static analysis tool for Groovy, and I would love to see more people using it to improve their code quality.
There are my first thoughts after looking at the survey results. And what are yours? Let me know in the comments bellow. 👍
About the survey
The survey was launched on August 28th, and it was collecting the answers up to September 11th. It contained a single multi-choice question with predefined options to choose from, plus a text input to vote for a thing that was not mentioned on the list. It was announced using many communication channels, including the Groovy mailing list, Groovy Community Slack, Twitter, LinkedIn, Reddit, etc. The survey link was clicked 520 times, and it was converted to 308 responses (59.23% conversion rate.)
| This survey and its results do not represent the Groovy community choices as a whole. I did my best to survey as many community members as possible. However, I couldn’t reach out to every single person. Treat this report as trends radar, based on the data provided by some percentage of the active Groovy users. |
(PS: I will run a similar survey next year so that we can study changes in trends. 😉)
