Class not found? about krakatau

[Storyyeller]

It wasn't able to autodetect the standard library, so you'll need to pass

-path (your location of rt.jar)

for example -path "C:\Program Files (x86)\Java\jre7\lib\rt.jar"

You'll also need to pass the locations of any other libraries that the target references.

When I run the following

~/Downloads/Krakatau-master/decompile.py -path "/home/maurice/jdk1.8.0_65/jre/lib/rt.jar" ./path/to/my/classes/

I still get the "Unable to find the standard library" error. Do I have the syntax wrong somewhere? I assume if it were actually a different library missing at this point, it wouldn't still say "the standard library", right?

Same when I run

~/Downloads/Krakatau-master/decompile.py -path="/home/maurice/jdk1.8.0_65/jre/" ./path/to/my/classes/

and a few other variations.

Ok. I noticed the readme says "Note that the decompiler does not currently support Java 8[...]" so I installed 7 via apt, in the standard location, but am still getting the same error.

Which class did it say wasn't found? It's probably needs another library.

Each time it says a class is missing, just add the jar with that class to
the path.

Hi,

I have a .jar. I wish to deobfuscate it and run it in eclipse. Krakatau seems very promising for this. While running it I am also getting the same message on my console. I run the command as following:

C:\Python27> .\python.exe <pathTo\decompile.py> -path "C:\Program Files\Java\jr
1.8.0_144\lib\rt.jar" -out -r -skip

Message on Powershell is as following:

Also, as you can see it does not tell me which are the standard libraries it needs. I am unable to figure out what is going wrong. Kindly help me here.

Note: I would also like to know how did you figure out rt.jar was to be included in the path? (from the first question asked here by IvoPereira)

If there is a class missing, and you don't pass -skip, it will tell you the name of the class. You can usually figure out which dependency you need by googling the name of the class. I agree that it's a terrible system (I'm annoyed by it as much as you), but I'm not sure how to improve it, as redesigning Krakatau to not require class hierarchy information is a nonstarter.
