Question

我正在尝试从Spring Initilizr配置Spring-Boot项目。
依赖关系-> kafka，web

当我导入该项目时，在行

的pom.xml中出现错误

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.6.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

为

Project build error: Non-resolvable parent POM for com.mobicule.kafkaexample:Spring-Producer:0.0.1-SNAPSHOT: Cannot 
 access central (https://repo.maven.apache.org/maven2) in offline mode and the artifact org.springframework.boot:spring-boot-
 starter-parent:pom:2.0.6.RELEASE has not been downloaded from it before. and 'parent.relativePath' points at no local POM

</project>

在我的首选项下已检查“嵌入式”安装。这会引起任何问题吗？
我还需要单独在Eclipse中进行Maven安装才能运行此项目吗？

请指导我，因为我无法理解任何行家错误

Answer 1

您处于离线模式。看到异常

以离线模式访问中心（https://repo.maven.apache.org/maven2）和工件org.springframework.boot：spring-boot- starter-parent：pom：2.0.6.RELEASE尚未从其下载。

您使用什么IDE？

编辑：在Eclipse中转到：窗口/首选项/ Maven->第一个复选框将Maven设置为脱机模式。检查是否已选择。如果选择->取消选择，然后尝试重新构建（全新安装）

设置Spring-Boot Maven项目
