Will tools.build be released as a jar?

Wed, 05 Jan 2022 15:02:43 +0000

I am developing a library with a dependency on tools.build and I would like to publish it as a jar. Whilst tools.build is only available as a git dep, I cannot include it as a dependency in my pom file. A wider discussion on this topic was held on this slack thread, where @alexmiller requested that I raise this topic here.

tools.build/jar doesn't support "sections" in manifest

Sections are groups which start with Name: and have section-specific entries in them.

Capsule uses this for having platform-specific information about how to start.

Here's an example of using the API to get section information:

Main-Class: clojure.main

Name: Frank
Main-Class: frank.clojure.main

and

❯ clj       
Clojure 1.10.3
user=> (require '[clojure.java.io :as io])
nil
user=> (io/input-stream "/tmp/MANIFEST.MF")
#object[java.io.BufferedInputStream 0x69ce2f62 "java.io.BufferedInputStream@69ce2f62"]
user=> (def mf (java.util.jar.Manifest. (io/input-stream "/tmp/MANIFEST.MF")))
#'user/mf
user=> (.getAttributes mf "Frank")
{#object[java.util.jar.Attributes$Name 0x2e3a5237 "Main-Class"] "frank.clojure.main"}
user=> (.getMainAttributes mf)
{#object[java.util.jar.Attributes$Name 0x2e3a5237 "Main-Class"] "clojure.main"}
user=> (.getEntries mf)
{"Frank" {#object[java.util.jar.Attributes$Name 0x2e3a5237 "Main-Class"] "frank.clojure.main"}}
