Clojure程序读取自己的MANIFEST.MF [英] Clojure program reading its own MANIFEST.MF

问题描述

Clojure程序如何找到自己的MANIFEST.MF（假设它被打包在JAR文件中）。

How can a Clojure program find its own MANIFEST.MF (assuming it is packaged in a JAR file).

我试图从我的 main函数，但我找不到一个类在以下代码中使用：

I am trying to do this from my "-main" function, but I can't find a class to use in the following code:

  (.getValue
    (..
      (java.util.jar.Manifest.
        (.openStream
          (java.net.URL.
            (str
              "jar:"
              (..
                (class **WHAT-GOES-HERE**)
                getProtectionDomain
                getCodeSource
                getLocation)
              "!/META-INF/MANIFEST.MF"))))
      getMainAttributes)
    "Build-number"))

Thanks.

推荐答案

这似乎可靠地工作：

(defn set-version
  "Set the version variable to the build number."
  []
  (def version
    (.getValue (.. (Manifest.
      (.openStream
        (URL.
          (str "jar:"
            (.getLocation
              (.getCodeSource
                (.getProtectionDomain org.example.myproject.thisfile)))
            "!/META-INF/MANIFEST.MF"))))
      getMainAttributes)
      "Build-number")))
