Java and Clojure with Leiningen
提问by Toby Hede
Is it possible to easily manage and compile native Java classes alongside Clojure in a project using leiningen?
是否可以使用 leiningen 在项目中与 Clojure 一起轻松管理和编译本机 Java 类？
I am working at a pretty low level (with netty nio) and thinking that some of the plumbing classes would actually be easier to handle as raw java both in terms of constructing the code as well as performance.
我在一个相当低的级别（使用 netty nio）工作，并认为在构建代码和性能方面，一些管道类实际上更容易作为原始 Java 处理。

As of Leiningen 2.x, :java-source-pathhas been replaced with :java-source-paths, whose value is now specified as a vector rather than a string.
从 Leiningen 2.x 开始，:java-source-path已替换为:java-source-paths，其值现在指定为向量而不是字符串。
A good place to find a full (up-to-date) documentation of Leiningen features is to peruse the sample project file. In this case, you will see:
查找 Leiningen 功能的完整（最新）文档的一个好地方是仔细阅读示例项目文件。在这种情况下，您将看到：
:java-source-paths ["src/main/java"]
:java-source-paths ["src/main/java"]

In Leiningen tutorialthere is following statement
在莱宁根教程中有以下声明
For projects that include some Java code, you can set the :java-source-path key in project.clj to a directory containing Java files. Then the javac compiler will run before your Clojure code is AOT-compiled, or you can run it manually with the javac task.
对于包含一些 Java 代码的项目，您可以将 project.clj 中的 :java-source-path 键设置为包含 Java 文件的目录。然后 javac 编译器将在您的 Clojure 代码被 AOT 编译之前运行，或者您可以使用 javac 任务手动运行它。
so it should work out of box if :java-source-pathsoption is set
所以如果:java-source-paths设置了选项，它应该是开箱即用的

Use Vinyasa- I wrote it especially to deal with this problem
