新建了一个maven项目，需要依赖其他项目，当mvn install的时候就出错

Posted 2023-04-01

出错的提示：
The project com.cisetech.emp:emp-meettingbook-web:0.0.1-SNAPSHOT (F:\some\1.27\trunk\emp-meettingbook-web\pom.xml) has 1 error
[ERROR] Non-resolvable parent POM: Could not find artifact com.cisetech.emp:emp-parent:pom:0.0.1-SNAPSHOT and 'parent.relativePath' points at wrong local POM @ line 4, column 13 -> [Help 2]

最佳回答：

在此行找到多个注释：

- 生命周期配置中没有涉及的插件执行：org.apache.maven.plugins：maven-compiler-plugin：3.2：testCompile（execution：default-

testCompile，阶段：测试编译）

- CoreException：无法计算构建计划：插件org.apache.maven.plugins：maven-compiler-plugin：3.2或其一个依赖不能

已解决：无法读取org.apache.maven.plugins的工件描述符：maven-compiler-plugin：jar：3.2：ArtifactResolutionException：无法传输

org.apache.maven.plugins：maven-compiler-plugin：pom：3.2从https://repo.maven.apache.org/maven2缓存在本地仓库中，解析不会

重新尝试，直到中央的更新间隔已过或更新被强制。原始错误：无法传输工件org.apache.maven.plugins：maven-

编译器插件：pom：3.2从/到中央（https://repo.maven.apache.org/maven2）：连接超时

- 生命周期配置不包含的插件执行：org.apache.maven.plugins：maven-compiler-plugin：3.2：compile（execution：default-compile，

阶段：编译）

参考技术A 你的pom继承了父类pom，但是你的本地库中没有父类pom，无法解析

接口抽取及依赖版本统一介绍

前面的项目，我们会发现有个接口是一样的，我们需要单独抽取出来，统一维护；

以及两个项目的maven依赖包的版本也是一样的，我们也需要单独抽取出来，统一维护；

 

抽取接口，我们通过新建一个项目，然后其他两个项目依赖这个这个项目即可；

统一依赖包版本，我们可以通过建立parent项目，来统一管理依赖以及版本，子项目继承即可；

 

我们新建dubbo-demo-api项目，然后把DemoProviderService接口类放到该项目里即可；

 

 1 /**
 2  * 
 3  */
 4 package com.hik.service;
 5 
 6 /**
 7  * @ClassName: DemoProviderService
 8  * @Description: 服务提供者接口
 9  * @author jed
10  * @date 2018年8月25日下午11:52:57
11  *
12  */
13 public interface DemoProviderService {
14 
15     public String sayHello(String name);
16 }

我们再新建一个dubbo-demo-parent项目；

pom.xml里：

类似，dubbo-demo-consumer项目pom.xml修改：
