leiningen uberjar doesn't add manifest attribute
I am unsuccessfully trying to run instant-pdf
lein uberjar
cd target
java -jar instant-pdf-0.2.0-standalone.jar
no main manifest attribute, in instant-pdf-0.2.0-standalone.jar
Do I have to manually edit the jar now?
I am using OpenJDK 7.u13-x86_64.
instant-pdf's project.clj lacks a :main setting, and I bet that's why it's not setting a main class in the jar's manifest. However, the project doesn't specify a main method anywhere in the sources either, so you'd have to add one yourself. See the section on Running Code from the Leningen Tutorial for details on using :main .
@Yogothos pointed out that using the Ring plugin for Leiningen will fix this (quoting his comment below):
The project should be built using lein ring uberjar instead of lein uberjar . The Ring plugin is responsible for creating the main.
