intellij idea maven打包总是去下载包,但是我本地已经有了啊?

Question

通过命令打包 : mvn package pom.xml <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

Answer 1

mvn clean install test

Answer 2

可能两次依赖包的版本不一致，你可以去本地仓库看一下是否一个包下有多个版本。

Answer 3

首先要先确认idea里的maven和外部的maven用的是不是一个settings.xml

Answer 4

是不是用了idea自带的maven了

Answer 5

仔细检查一下setting.xml的配置
