项目历史

The official GitHub repository was created in May 2014 and points users to benf.org as the main CFR site. The README says CFR can decompile modern Java features, including Java 9, 12, and 14 features, and can make a reasonable attempt at JVM languages such as Kotlin, Scala, and Groovy.

The benf.org project page records a long release history, including 0.146 in July 2019, 0.147 in October 2019, 0.150 in May 2020, 0.151 in February 2021, and 0.152 in December 2021. The README notes that since 0.145, binaries have also been published on GitHub releases.

采用历史

CFR's adoption comes from the Java reverse-engineering and debugging niche: developers use it when they need readable Java-like output from class files or jars, especially for newer language features that older decompilers may not handle cleanly.

Official distribution includes the benf.org jar downloads, GitHub release artifacts, and Maven Central. The Homebrew package wraps that Java tool in a package-manager-friendly executable for macOS users.

使用方式

The documented use is to run the versioned jar against class names or class files, or pass an entire jar and an `--outputdir` when emitting files. The README also documents `--help` for arguments.

CFR supports an options file for decompilation tests, but the official user docs do not document a persistent application config path or credential file for normal CLI use, so both locations are null.

为什么软件包爱好者会关心

CFR matters to package people because decompilers are operational tools as much as developer tools: they are installed when source is missing, artifacts are suspicious, or bytecode behavior needs inspection.

It is also a classic example of a small Java jar that package managers wrap into a named executable. The package value is not dependency complexity; it is putting a known decompiler on PATH.
