Gradle vs Vineflower

Gradle Build Tool is a free, open-source system for automating software builds across projects of different types and sizes. Build logic can use either Kotlin DSL or Groovy DSL. Incremental builds, caching and parallel task execution support the build process, while Gradle downloads and manages transitive dependencies from Maven- and Ivy-compatible repositories. The Gradle Wrapper can provision a build environment and specify the Gradle version used by a project. Its ecosystem covers JVM, Android, C/C++, Swift, Objective-C and assembler projects, and it runs on Windows, macOS and Linux. The Tooling API lets IDEs and other tools inspect projects, run builds, receive progress events and cancel operations. Listed support includes Android Studio and Ant, plus Checkstyle, CodeNarc, PMD and JaCoCo. Gradle includes dependency verification. The maker says open-source security fixes are limited by its end-of-life policy; its Security Subscription offers prioritized fixes under SLA and extended maintenance, but does not guarantee a clean scanner report when findings come from third-party libraries.

Vineflower is a free, open-source Java decompiler for producing readable code from Java classes. It supports modern Java, including J21 and later, with automatic reformatting and multithreaded decompilation. The main distribution is a JAR from GitHub releases and Maven Central. You can run that JAR from the command line with archives or files, saving output to an archive or folder or printing it to the console. Vineflower can also be added through Maven or Gradle, and an IntelliJ plugin is available. A command-line option can emit Kotlin classes as Kotlin; the full distribution includes an experimental Kotlin decompiler plugin and other plugins for IntelliJ IDEA annotations and variable renaming. A slim artifact omits built-in plugins. Running requires a Java 17 or newer JVM. An experimental plugin system supports output changes or new JVM languages. The project calls itself a work in progress and welcomes contributions. It is licensed under Apache-2.0.
