java - 为什么maven从spring repo下载jar？

Question

我在 settings.xml 和 pom.xml 中有一个像这样的镜像

设置.xml

  <?xml version="1.0" encoding="UTF-8"?>

但是当我尝试编译我的项目时，我得到了这个错误:

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

1. 我试图删除本地仓库或 mvn clean compile -U
下的所有文件夹
2. 我用 settings.xml 和 pom.xml 尝试了 grep "repo.spring.io"但一无所获
3. 只使用对我有用的单一存储库。

像这样:

<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maven为什么要从spring repo下载这个依赖？

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>

这将正确地将所有在您自己或其他 pom(如 spring-boot 存储库)中定义的请求重定向到您的内部存储库管理器。
