但是当我尝试编译我的项目时，出现此错误：

Could not find artifact com.my.package:httpclient-starter:jar:1.0.0-SNAPSHOT
in spring-snapshot (https://repo.spring.io/snapshot)

我试图删除本地存储库或mvn clean compile -U下的所有文件夹
我用settings.xml和pom.xml尝试了grep“ repo.spring.io”
仅对我使用单个仓库。

赞：

<mirror>
  <id>my-id</id>
  <mirrorOf>*</mirrorOf>
  <name>any name</name>
  <url>http://anyHost:2227/repository/maven-public</url>
</mirror>

我怎么知道为什么Maven从Spring Repo下载了这个依赖项？

Answer 1

使用存储库管理器的正确settings.xml设置应如下所示：

<settings>
  <mirrors>
    <mirror>
      <!--This sends everything else to /public -->
      <id>nexus</id>
      <mirrorOf>*</mirrorOf>
      <url>http://localhost:8081/nexus/content/groups/public/</url>
    </mirror>
  </mirrors>
  <profiles>
    <profile>
      <id>nexus</id>
      <!--Enable snapshots for the built in central repo to direct -->
      <!--all requests to nexus via the mirror -->
      <repositories>
        <repository>
          <id>central</id>
          <url>http://central</url>
          <releases><enabled>true</enabled></releases>
          <snapshots><enabled>true</enabled></snapshots>
        </repository>
      </repositories>
     <pluginRepositories>
        <pluginRepository>
          <id>central</id>
          <url>http://central</url>
          <releases><enabled>true</enabled></releases>
          <snapshots><enabled>true</enabled></snapshots>
        </pluginRepository>
      </pluginRepositories>
    </profile>
  </profiles>
  <activeProfiles>
    <!--make the profile active all the time -->
    <activeProfile>nexus</activeProfile>
  </activeProfiles>
  <servers>
    <!-- Possible authentications for access to nexus -->
    <server>
      <id>snapshots</id>
      <username>xxx</username>
      <password>xxx</password>
    </server>
    <server>
      <id>releases</id>
      <username>xxx</username>
      <password>xxx</password>
    </server>
  </servers>
</settings>

这将正确地将您自己或其他pom（例如spring-boot仓库）中定义的所有请求重定向到内部存储库管理器。

Answer 2

让我们从从Spring的快照存储库下载Maven的部分开始。从您向我们展示的问题来看，至少不清楚（如果不存在）您在项目中定义了任何快照存储库。因为这是一个Spring Boot项目，所以它将通过父项目（..repo.spring.io..）为您设置一个。这就是为什么您的项目可以访问此特定服务器的原因。

您尝试下载您可能自己放到一个连结的罐子，对不对？该版本为<sth>-SNAPSHOT，使Maven尝试从某些快照服务器获取。

您的镜子必须是mirrorOf的中央存储库，我只是假设您的jar不在其中，而是在镜子中。

我的想法是像这样将镜像设置为项目pom.xml中的存储库

<repositories>
  <repository>
    <id>myInternalRepository</id>
    <url>http://localhost:8081/nexus/content/groups/???</url>
    <snapshots>
      <enabled>true</enabled>
    </snapshots>
</repository>

Answer 3

在repo.spring.io中没有看到这个jar“ httpclient-starter：jar：1.0.0-SNAPSHOT ”。

1）尝试在浏览器中打开 repo.spring.io 。然后检查是否存在相应的jar，并在settings.xml配置中检查代理设置。

https://repo.spring.io/snapshot

Maven Proxy settings

2） com.my.package：httpclient-starter：jar：1.0.0-SNAPSHOT（如果存在），然后从.m2存储库中手动删除

3）mvn全新安装。

4）如图所示，检查您的RepositoryId和存储库名称。

Answer 4

您可以使用命令maven install将jar httpclient-starter：jar：1.0.0-SNAPSHOT 安装到本地Maven存储库中

为什么maven从spring repo下载jar？
