pom.xml

除了引用的包之外.我只設置了:
<build><plugins> <plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId> </plugin></plugins> </build>這是必須的.應該不影響
和 jdk版本配置
為什么每次都要去下載呢 ?
問題解答
回答1：mvn clean install test
回答2：可能兩次依賴包的版本不一致，你可以去本地倉庫看一下是否一個包下有多個版本。
回答3：首先要先確認idea里的maven和外部的maven用的是不是一個settings.xml
