NeoGradle vs Vineflower

NeoGradle has no write-up on Specifiction yet; its figures are above.

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.
