Tool

CFR

CFR decompiles Java class files and jars, including Java 9, 12, and 14 features, and is written in Java 6. The main class is org.benf.cfr.reader.Main. A jar path plus --outputdir writes the decompiled files. mvn compile builds it. Since 0.145, binaries are published with GitHub release tags and on Maven Central as org.benf:cfr.
