Question

我尝试配置一个使用clojure的Maven项目，我想在其中启动nrepl。
我用这个配置做了一个最小的maven项目：

<!-- some standard pom stuff -->
<dependencies>
    <dependency>
        <groupId>org.clojure</groupId>
        <artifactId>clojure</artifactId>
        <version>1.9.0</version>
    </dependency>
</dependencies>

<build>
<plugins>
    <plugin>
      <groupId>com.theoryinpractise</groupId>
      <artifactId>clojure-maven-plugin</artifactId>
      <version>1.8.1</version>
      <extensions>true</extensions>
      <dependencies>
          <dependency>
              <groupId>org.clojure</groupId>
              <artifactId>tools.nrepl</artifactId>
              <version>0.2.13</version>
          </dependency>
      </dependencies>
    </plugin>
</plugins>
<!-- other maven standard stuffs -->

当我mvn clojure:nrepl时出现此错误：

[INFO] --- clojure-maven-plugin:1.8.1:nrepl (default-cli) @ clojure-maven-integration ---

根据the docs，

clojure：nrepl目标需要org.clojure / tools.nrepl作为项目依赖

尝试将插件中的依赖项移动到您已声明对Clojure的依赖的位置。

示例POM：

<?xml version="1.0" encoding="UTF-8"?>

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>

  <groupId>foo</groupId>
  <artifactId>bar</artifactId>
  <version>1.0-SNAPSHOT</version>

  <name>bar</name>
  <description>A simple bar.</description>

      <artifactId>tools.nrepl</artifactId>
