Gradle Bintray Plugin
The Gradle Bintray Plugin allows you to publish artifacts to Bintray
The Gradle Bintray Plugin allows you to publish artifacts to Bintray. The plugin supports three methods to create groups of artifacts: Configurations, Publications and Copying specific files using filesSpec. One of the methods should be used to group artifacts to be uploaded to Bintray. Using the Configurations approach is the easiest, since this option attempts to infer what artifacts to upload based on the Gradle project and dependencies that are defined. Publications gives more fine-grained control, especially when needing to publish metadata for publishing to Maven Central. Copying specific files can be used as a last option, which provides the ability to define custom rules using the Gradle's CopySpec task. In general, the first two options should be sufficient for your needs. -

OkReplay
Record and replay OkHttp network interaction in your tests
OkReplay is a tool for recording and replaying HTTP interactions (specifically via OkHttp) in Android tests to improve determinism, test speed, and reliability. During the first run of a test annotated with @OkReplay, the library records outgoing HTTP requests and their responses into tape files. On subsequent runs, it intercepts those requests and serves the recorded responses instead of making real network calls. This allows tests to be executed offline, reduces flakiness due to network variability, and isolates the test environment from external dependencies. OkReplay integrates with testing frameworks such as JUnit and Espresso, so it fits naturally into Android testing pipelines. Because recording only happens when running with the annotation, production code paths remain unaffected. It’s especially useful when your app’s logic depends on network APIs and you want faster, more reliable unit or integration tests. -

Clouddriver
Read and write operations across cloud providers
Clouddriver is the cloud-provider integration layer of Spinnaker, exposing a uniform API and cache for infrastructure resources across multiple clouds. It discovers and tracks entities such as server groups, load balancers, security groups, images, and instances, normalizing them so higher-level services can reason consistently. The service also brokers mutating operations—like creating server groups or resizing clusters—by translating Spinnaker requests into provider-specific calls. A scalable caching subsystem maintains near-real-time views of accounts and regions to keep UI and pipelines responsive. Credentials, permissions, and account configuration are managed centrally, enabling multi-account, multi-region deployments at scale. In practice, Clouddriver is the backbone that lets Spinnaker orchestrate hybrid and multi-cloud delivery with a single pane of glass. -

Fabric8 Pipeline Library
Fabric8 Pipeline for Jenkins
This repository is a Jenkins Shared Library that packages reusable pipeline steps and patterns for building, testing, and releasing containerized applications to Kubernetes and OpenShift. It codifies best practices—building images, running unit/integration tests, publishing artifacts, and rolling out changes—so teams can adopt a consistent CI/CD approach with minimal Groovy code. The library includes helpers for preview environments, GitOps-style promotion, and release versioning to improve traceability across stages. Because it abstracts low-level CLI invocations, pipelines become more declarative and easier to review. It encourages composable, parameterized pipelines that work across many repositories while still allowing per-service overrides. Organizations use it to bootstrap platform-aligned pipelines quickly and reduce drift in how services are built and deployed. -

Lazybones
A simple project creation tool that uses packaged project templates
Lazybones is a project creation tool and template manager for Groovy and JVM-based applications. It allows developers to generate new projects from templates with a simple command, filling in details such as project structure, configuration files, and boilerplate code. Templates can be customized or created from scratch, making it easy to enforce consistent setups across teams or organizations. Lazybones supports updating existing projects from newer versions of templates, easing long-term maintenance. It is commonly used to bootstrap Grails, Ratpack, or Gradle-based projects, but it can handle any JVM project layout. By automating the scaffolding process, Lazybones reduces setup time and encourages best practices by distributing pre-approved templates. -
