Vineflower
Vineflower is a modern general purpose Java & JVM language decompiler focused on providing the best quality, speed, and usability.
Vineflower's features include:
- Java 21+ support, including records, sealed classes, switch expressions, pattern matching, and more
- Clean code generation and output, with automatic output formatting
- Multithreaded decompilation
Examples of Vineflower's output compared to other decompilers can be found on the website.
Use
Vineflower can be used from the console or as a library. To run Vineflower from the command line, download the latest release from the Releases tab.
You can then run Vineflower with java -jar vineflower.jar <arguments> <source> <destination>.
<arguments> is the list of commandline arguments that you want to pass to the decompiler.
<source> can be a jar, zip, folder, or class file, and <destination> can be a folder, zip, jar, or omitted to print to the console.
To use Vineflower as a library, you can find distributions on maven central. Vineflower 1.9+ requires Java 11 or higher to run, and Vineflower 1.11+ requires Java 17 or higher to run. Vineflower can be addded as a dependency in gradle with:
dependencies {
implementation 'org.vineflower:vineflower:<version>'
}
More instructions on how to interface with Vineflower can be found on the website.
For IDE use, the Vineflower Intellij IDEA plugin replaces Fernflower in IDEA with Vineflower.
Please report any issues to the Issues tab!
