我正尝试创建一个项目，就像跷跷板示例window-builder一样，我创建了一个名为my-gui-project的项目，并复制了src/window_builder/core.clj和src/window_builder/MyForm.java中的代码进入我的项目，然后更改第31行的内容：
(let [form (identify (window_builder.MyForm.))]
进入：
(let [form (identify (my_gui_project.MyForm.))]。
然后，我运行以下命令：lein deps，lein compile和lein run -m my-gui-project.core，它返回以下错误：
Exception in thread "main" java.lang.ClassNotFoundException: my_gui_project.MyForm, compiling:(my_gui_project/core.clj:31:24)
为什么会这样？代码完全相同，我只是更改了文件夹名称。
这是完整的代码：
core.clj：
(ns my-gui-project.core
(:gen-class)
(:use [seesaw.core])
(:require [seesaw.selector :as selector]))
; This is the interesting part. Note that in MyPanel.java, the widgets we're
; interested in have their name set with setName().
(defn identify
"Given a root widget, find all the named widgets and set their Seesaw :id
so they can play nicely with select and everything."
[root]
(doseq [w (select root [:*])]
(if-let [n (.getName w)]
(selector/id-of! w (keyword n))))
root)
(def states ["CA", "GA", "WA"])
(def defaults
{ :first-name "Laura"
:last-name "Palmer"
:street "123 Main St."
:city "Twin Peaks"
:zip "12345"
:state "WA" })
; A helper to create an instance of the form, annotate it for Seesaw and do
; some other initialization.
(defn my-form
[]
(let [form (identify (my_gui_project.MyForm.))]
; initialize the state combobox
(config! (select form [:#state]) :model states)
form))
; Now we just create the panel, initialize it to the defaults above with
; seesaw.core/value! and show it in a dialog. Note how, besides setting the
; names of the widgets, the code in MyForm.java is strictly for layout. All
; behavior, etc is done in Clojure.
(defn -main [& args]
(invoke-later
(let [form (value! (my-form) defaults)
result (-> (dialog :content form :option-type :ok-cancel) pack! show!)]
(if (= :success result)
(println "User entered: " (value form))
(println "User canceled")))))
project.clj：
(defproject my-gui-project "0.1.0-SNAPSHOT"
:description "FIXME: write description"
:url "http://example.com/FIXME"

通过测试，我发现MyForm.java内还引用了项目名称。更改MyForm.java中的名称后，它就可以使用。
编辑：正如@Carcigenicate在帖子（现已删除）中所引用的那样，还需要在:java-source-paths ["src"]

您可能还需要重命名window_builder目录以匹配名称更改。并更改任何Java文件中的程序包名称。
这与directory_name / namespace.clj的Clojure中的项目命名模式保持一致，并且-切换为_。
