Unable to use CFR about cfr

[leibnitz27]

That's very odd, there's quite definitely a manifest.

Please check the jar you have matches the md5 on the website.

Also try without a jar file

lee@rick:/mnt/c/Downloads$ java -jar cfr-0.148.jar
CFR 0.148

java -jar CFRJAR.jar class_or_jar_file [method] [options]

Parameter error : Insufficient unqualified parameters - provide at least one filename.

Please specify '--help' to get option list, or '--help optionname' for specifics, eg
   --help pullcodecase

C:\Downloads>java -jar cfr-0.148.jar
CFR 0.148

java -jar CFRJAR.jar class_or_jar_file [method] [options]

Parameter error : Insufficient unqualified parameters - provide at least one filename.

Please specify '--help' to get option list, or '--help optionname' for specifics, eg
   --help pullcodecase

I tried without the jar file, the result is still the same

What is the md5 & size of the jar you have? can you please check it matches https://www.benf.org/other/cfr/cfr-0.148.jar ?

[leibnitz27]

You should be able to see the main class in the manifest here:

lee@rick:/mnt/c/Downloads$ unzip -p cfr-0.148.jar META-INF/MANIFEST.MF

ping @thefourtheye - tbh I suspect you have a bad jar - would be handy if you can try the above.

[leibnitz27]

Closing as not reproducible and dead (pls reopen if you have additional info)

[thefourtheye]

@leibnitz27 You were right. Looks like the jar file was not correct. I wonder how java managed to parse it.

I should have updated this thread sooner, please accept my sincere apology.

No problem, thanks for following up!
