Can't execute jar- file: “no main manifest attribute”

Question

I have installed an application, when I try to run it (it\'s an executable jar) nothing happens. When I run it from the commandline with:

java -jar \

Answer 1

For me, none of the answers really helped - I had the manifest file in correct place, containing the Main-Class and everything. What tripped me over was this:

Warning: The text file from which you are creating the manifest must end with a new line or carriage return. The last line will not be parsed properly if it does not end with a new line or carriage return.

(source). Adding a newline at the end of the manifest fixed it.
