heroku - 全新的 Luminus 应用程序给出错误 : Could not find or load main class clojure. main

Question

我刚刚通过运行创建了一个 Luminus 应用:

lein new luminus foobar

当我尝试像这样与工头一起运行它时:

foreman start

文档描述的方式，我得到这个错误:

Error: Could not find or load main class clojure.main

这也是我从 Heroku 得到的相同错误。模板创建的 Procfile 包含以下内容:

web: java $JVM_OPTS -cp target/foobar.jar clojure.main -m foobar.core

这是怎么回事，我该如何解决？

Answer 1

我最好的猜测是您需要使用命令 lein uberjar 来构建项目。此序列有效:

$ lein new luminus foobar
Retrieving ...
Generating a Luminus project.

$ cd foobar
$ lein uberjar
Retrieving ...
Compiling foobar.session
Compiling foobar.layout
Compiling foobar.handler
Compiling foobar.routes.home
Compiling foobar.core
Compiling foobar.middleware
Created /home/ba/foobar/target/foobar-0.1.0-SNAPSHOT.jar
Created /home/ba/foobar/target/foobar.jar

$ cat Procfile 
web: java $JVM_OPTS -cp target/foobar.jar clojure.main -m foobar.core

$ java $JVM_OPTS -cp target/foobar.jar clojure.main -m foobar.core
