混合的Clojure和Java项目的Maven

Question

我有Maven项目，在目录src/main/clojure我已经把代码：https://github.com/8protons/url62/blob/master/src/url62/core.clj

我想从src/main/java在Java代码中执行功能generate-id。

IFn require = Clojure.var("clojure.core", "require"); 
require.invoke(Clojure.read("url62.core")); 

IFn plus = Clojure.var("url62.core", "generate-id"); 
Object result = plus.invoke(UUID.randomUUID().toString()); 
System.out.println(result); 

Maven配置：

<package>jar</package> 

<dependencies> 
    <dependency> 
     <groupId>org.clojure</groupId> 
     <artifactId>clojure</artifactId> 
     <version>1.8.0</version> 
    </dependency> 
</dependencies> 

<build> 
    <plugins> 
     <plugin> 
      <groupId>com.theoryinpractise</groupId> 
      <artifactId>clojure-maven-plugin</artifactId> 
      <version>1.8.1</version> 
      <extensions>true</extensions> 
      <executions> 
       <execution> 
        <id>compile</id> 
        <goals> 
         <goal>compile</goal> 
        </goals> 
       </execution> 
      </executions> 
     </plugin> 
    </plugins> 
</build> 

编译没有

target/classes/ 
├── core.clj 
└── url62 
    ├── core.clj 
    ├── core$fn__3.class 
    ├── core$generate_id.class 
    ├── core__init.class 
    ├── core$int_to_base62.class 
    └── core$loading__5569__auto____1.class 

而且Java代码失败：

clojure.lang.ArityException: Wrong number of args (1) passed to: core/generate-id 

at clojure.lang.AFn.throwArity(AFn.java:429) 
at clojure.lang.AFn.invoke(AFn.java:36) 
at clojure.lang.Var.invoke(Var.java:383) 
at url62.Url62Test.name(Url62Test.java:17)

好，clojoure功能没有参数:(

Object result = plus.invoke();
