我在弹簧模板项目的mi maven pom.xml中收到以下错误

"描述资源路径位置类型ArtifactDescriptorException:无法读取org.slf4j的工件描述符:slf4j-api:jar:1.5.6:ArtifactResolutionException:无法从http:/传输org.slf4j:slf4j-api:pom:1.5.6 /repo.maven.apache.org/maven2缓存在本地存储库中,在中心的更新间隔过去或强制更新之前,不会重新尝试解析.原始错误:无法传输工件org.slf4j:slf4j-api: pom:1.5.6 from/to central(http://repo.maven.apache.org/maven2):C:\ Users\muhsin.HIFX.m2\repository\org\slf4j\slf4j-api\1.5.6\slf4j-api-1.5.6.pom.ahc0570cfa3a1934af5(系统找不到指定的文件)pom.xml/sample line 1 Maven Dependency Problem"

Answer 1

您还可以使用强制更新标志(-U),例如:

 mvn clean install -U

Answer 2

根据错误信息

“描述资源路径位置类型ArtifactDescriptorException：无法读取org.slf4j：slf4j-api：jar：1.5.6的工件描述符，ArtifactResolutionException：无法从http：/转移org.slf4j：slf4j-api：pom：1.5.6 /repo.maven.apache.org/maven2 已缓存在本地存储库中，直到中心的更新间隔过去或强制执行更新后，才会重新尝试解析。

这意味着您必须删除文件夹$ HOME / .m2 / repository / org / slf4j，然后需要通过以下方式进行重建

mvn clean package

和其他给定的错误信息：

原始错误：无法从/到中央（http://repo.maven.apache.org/maven2）传输工件org.slf4j：slf4j-api：pom：1.5.6：C：\ Users \ muhsin.HIFX.m2 \ repository \ org \ slf4j \ slf4j-api \ 1.5.6 \ slf4j-api-1.5.6.pom.ahc0570cfa3a1934af5（系统找不到指定的文件）pom.xml / sample第1行Maven依赖问题”

表示您的存储库访问存在某种问题。您的代理服务器配置不正确。我建议使用存储库管理器，使工作更轻松。
