Error: "Java-Bean. Ensure that the manifest does not have duplicate entries, and that blank lines separate individual sections in both ..."

Question

I am trying to run a java jar file on a Windows 10 os in my bash terminal, and keep getting this error message:

Duplicate name in Manifest: Java-Bean. Ensure that the manifest does not have duplicate entries, and that blank lines separate individual sections in both your manifest and in the META-INF/MANIFEST.MF entry in the jar file

I tried updating my java path variables, and looking for this META-INF folder, but I'm not sure where to find it.

Also, here is the command that I am entering:

java -jar ManualSentimentClassifier.jar train.csv test.csv positive.txt negative.txt

Any ideas?

Thanks!

Update: I fixed this issue by opening the jar file archive (using 7zip). I navigated to the META-INF folder and edited the MANIFEST.MF file and removed the duplicated Java Bean information. After I did this, I no longer got the error
