invalid CEN header (encrypted entry) #193

Open mohanr opened 6 years ago

mohanr commented 6 years ago

Does this have anything to do with obfuscation of the decompiled class files ? I do see the method names in the left panel. But when I try to view the source I see this error.

The archive is probably compressed with an unsupported compression type.

Java's built in zip/jar library supports only type 0 (uncompressed) and type 8 (deflate).

Try decompressing the jar with a 3rd party tool, then either recompressing with type 0/8 or working directly off the extracted classes.

I have decompressed the class files. When I try to open one of them I see this. But I see the methods in the left panel. As you suggested I also compressed them again using 'jar', decompressed and tried to open the class files. Same error.

Hi. Without any other information, I can simply suggest you try again with the latest version.
