Leiningen has problems building a working uberjar

 

We're trying to build our Clojure project with Leiningen. We've succeeded in creating an uberjar by doing the following:

preconditions:

  • project.clj file lists dependencies
  • :main my-project.core in project.clj
  • a core.clj file with a -main function
  • (:gen-class :main true) in core.clj

    • procedure:

  • ran lein test ; completed with no failures
  • ran lein deps ; completed successfully
  • from project.clj's directory: rain lein uberjar
  • This created two jar files: My-Project-1.0.0-SNAPSHOT-standalone.jar, and My-Project-1.0.0-SNAPSHOT.jar.
  • ran java -jar BioClojure-1.0.0-SNAPSHOT-standalone.jar , which resulted in this exception:

    • Exception in thread "main" java.lang.SecurityException: Invalid signature file digest for Manifest main attributes

    My research into this problem has not been fruitful. Apparently, it's a known problem with no good solution. I do not understand the answers there.

    What do we need to do to get our uberjar working?

  • determine which of our dependencies is causing the problem?
  • remove dependencies from our project?
  • compile the project some other way?
  • patch leiningen?
  • use the suggested command: zip *-standalone.jar -d META-INF/DUMMY.SF (I have no idea what this does)
  • do something with :uberjar-exclusions in the project.clj file? (if so, what?)

    • Lein and java versions: 

    $ lein version
Leiningen 1.6.1 on Java 1.6.0_26 Java HotSpot(TM) 64-Bit Server VM

    Update: running the command suggested gives: 

    $ unzip -l BioClojure-1.0.0-SNAPSHOT-standalone.jar | grep -i -e ".sf"

   106  09-21-09 06:45   META-INF/maven/net.sf.opencsv/opencsv/pom.properties

    My understanding from reading the comments in that issue is that your problem would go away if you add the following to your project.clj 

    :uberjar-exclusions [#"foo.sf"]

    where foo.sf is the particular .sf file you want to ignore from the jar. You can determine this by running: 

    unzip -l BioClojure-1.0.0-SNAPSHOT-standalone.jar | grep -i -e ".sf"

    The suggested zip command deletes the particular file from the jar (which is of the ZIP format).
