This article explains the Java Runtime addShutdownHook API, its purpose for registering shutdown hooks, typical use cases such as resource cleanup, state saving, and logging, and provides practical Java and Groovy code examples while noting that hook execution order is unspecified.
This article benchmarks the Groovy 'as' type‑conversion keyword against native Java conversion methods for String‑to‑double, double‑to‑String, and double‑to‑int operations using JMH, revealing that Java's built‑in approaches consistently outperform Groovy's 'as' keyword across various test cases.
This article explains how Jenkins shared libraries enable team collaboration by allowing Groovy scripts to be shared and version‑controlled, demonstrates how to call a specific Groovy file and all Groovy files in a directory from build.groovy, and lists the operational benefits of using shared libraries.
This article explains how to use the parallel step and the Groovy collectEntries method in Jenkins Pipelines to run multiple jobs concurrently, reduce build time, and transform collections into maps for flexible stage generation, providing complete code examples and practical guidance.
This article provides an in‑depth tutorial on unit testing using Spock, covering its advantages over JUnit, core concepts like specifications, fixtures, feature methods, data‑driven testing, mock and stub techniques, interaction constraints, and tooling for automated test generation, all illustrated with Groovy and Java code examples.
This article introduces Groovy as a JVM scripting language, outlines its typical use cases, and provides a detailed, code‑rich tutorial on how to integrate Groovy scripts into a Spring Boot application, including dependency setup, script execution, bean access, and security considerations.

This tutorial explains how to install Spring Boot CLI, demonstrates the project layout, creates a Hello World application using Groovy, shows how to use @Grab for dependencies, run tests, package the app into an executable JAR, and generate new projects with the init command.
The report analyzes recurring morning Full GC alerts in a Java service, identifies a Groovy‑driven scheduled task as the root cause through JVM parameter review, log inspection, and memory profiling, and proposes concrete fixes such as reusing a single GroovyShell instance and clearing its classloader cache.
This article explains how to invoke other Groovy scripts and all Groovy files within a directory from a build.groovy file, providing concrete example code that demonstrates calling a Print method in hello.groovy and using it inside mytools.groovy.
This tutorial explains how to automatically create and delete Jenkins agent pods on a Kubernetes cluster for each pipeline run by storing Groovy scripts in a shared library, loading them with ScriptConsole, and invoking the Kubernetes API through Jenkins.
This article demonstrates how to programmatically create Jenkins agent nodes on demand with Groovy scripts, covering import statements, node configuration, adding the node to Jenkins, and retrieving node details for further automation in a CI/CD pipeline.
