Groovy
MentionedProgramming language
Dynamic JVM language with a concise syntax. Common in Gradle build scripts and Jenkins pipelines.
Groovy, explained
Written by EduVerseWhat it is
Groovy is a dynamic language that runs on the JVM and can use any Java library. Its syntax looks like a relaxed Java: semicolons, type declarations and a lot of boilerplate are optional, which makes it handy for scripts and configuration written as code.
Why teams use it
Groovy lets you script the JVM without Java’s ceremony, and its flexible syntax makes it easy to build small configuration languages on top of it. That is why Gradle’s build.gradle files and Jenkins pipelines use it. For new Gradle builds, many teams now pick the Kotlin variant instead.
An example from work
You need to add a library to a Java project and open build.gradle. The dependencies block, with lines starting with implementation, is Groovy, even though it reads more like configuration than code. Later you meet the same syntax in the Jenkinsfile that runs your team’s CI pipeline.
