    Dockerfile Maven

    Dockerfile Maven

    A set of Maven tools for dealing with Dockerfiles

    At this point, we're not developing or accepting new features or even fixing non-critical bugs. This Maven plugin integrates Maven with Docker. Don't do anything fancy. Dockerfiles are how you build Docker projects; that's what this plugin uses. They are mandatory. Make the Docker build process integrate with the Maven build process. If you bind the default phases, when you type mvn package, you get a Docker image. When you type mvn deploy, your image gets pushed. Make the goals remember what you are doing. You can type mvn dockerfile:build and later mvn dockerfile:tag and later mvn dockerfile:push without problems. This also eliminates the need for something like mvn dockerfile:build -DalsoPush; instead you can just say mvn dockerfile:build dockerfile:push. Integrate with the Maven build reactor. You can depend on the Docker image of one project in another project, and Maven will build the projects in the correct order.

    EA Async

    EA Async

    EA Async implements async-await methods in the JVM

    EA Async implements Async-Await methods in the JVM. It allows programmers to write asynchronous code in a sequential fashion. EA Async should be used to write non-blocking asynchronous code that makes heavy use of CompletableFutures or CompletionStage. It improves scalability by freeing worker threads while your code awaits other processes; And improves productivity by making asynchronous code simpler and more readable. The methods look blocking but are actually transformed into asynchronous methods that use CompletableFutures to continue the execution as intermediary results arrive.

    ENViews

    ENViews

    A cool dynamic view library

    ENViews is an Android UI library focused on delivering visually rich and dynamic animated components inspired by modern design concepts. It provides a collection of custom views that emphasize motion and interaction, including elements such as loading indicators, play buttons, search animations, and refresh effects. The library is based on design work by Nick Buturishvili, translating high-quality motion design concepts into reusable Android components. Its primary purpose is to enhance user experience by adding smooth, engaging animations that go beyond standard Android UI elements. ENViews is implemented in Java and integrates into Android projects via Gradle, making it easy to include in existing mobile applications. The library includes a demo project that showcases how each animated component behaves and how it can be implemented in real scenarios.

    Easy Random

    Easy Random

    The simple, stupid random Java beans/records generator

    Easy Random is a library that generates random Java objects. You can think of it as an ObjectMother for the JVM. The java.util.Random API provides 7 methods to generate random data: nextInt(), nextLong(), nextDouble(), nextFloat(), nextBytes(), nextBoolean() and nextGaussian(). What if you need to generate a random String? Or say a random instance of your domain object? Easy Random provides the EasyRandom API that extends java.util.Random with a method called nextObject(Class type). This method is able to generate a random instance of any arbitrary Java bean. Populating a Java object with random data can look easy at first glance, unless your domain model involves many related classes.

    EasyPermissions

    EasyPermissions

    Simplify Android M system permissions

    EasyPermissions is a wrapper library to simplify basic system permissions logic when targeting Android M or higher. If your app is written in Kotlin consider the easypermissions-ktx library which adds Kotlin extensions to the core EasyPermissions library. To begin using EasyPermissions, have your Activity (or Fragment) override the onRequestPermissionsResult method. If all of the permissions in a given request are granted, all methods annotated with the proper request code will be executed(be sure to have an unique request code). The annotated method needs to be void and without input parameters (instead, you can use onSaveInstanceState in order to keep the state of your suppressed parameters). This is to simplify the common flow of needing to run the requesting method after all of its permissions have been granted. Optionally, for a finer control, you can have your Activity / Fragment implement the PermissionCallbacks interface.
