Why do I write this?
When decompiling with Jetbrains' fernflower, the program freezes for a particular file or directory and cannot continue. In addition, the CPU usage is not high enough during decompiling, which makes decompilation slow.
So I developed this program based on fernflower to optimize these problems, with the following features
- multi-thread,
- progress bar
- breakpoint continue
- failure record
java 17 is required
usage: java -jar fernflowers.jar [args]
-h,--help help
-i,--input <arg> input, the directory to be scanned or a single file path.
-k,--backup don't delete the jar file in the output path when '--unzip' is specified
-n,--thread <arg> thread, default: 20
-o,--output <arg> output, the directory to saved result, default: current path.
-r,--resume skip the decompiled files (record in 'decompiled.txt') and continue
-u,--unzip unzip the jar file
After running for a period of time, almost all files are decomcompiled successfully, and the progress bar remains stuck, indicating that some jar packages have been decomcompiled incorrectly. You only need to terminate the program by Ctrl + C, and the program will automatically print out the wrong jar package path.
