Maven - 无法传输由存储库被阻止的镜像引起的工件

Question

通过 GitlabCI 部署 Maven 时出现此错误，docker image: maven:3-jdk-8。

Some problems were encountered while processing the POMs:
[FATAL] Non-resolvable parent POM for com.mycompany.app:app-all:0.9.3-SNAPSHOT: 
Could not transfer artifact com.mycompany:parent:pom:8 from/to maven-default-http-blocker (http://0.0.0.0/): 
Blocked mirror for repositories: [app-releases (http://nexus.mycompany.com/content/repositories/app-releases, default, releases+snapshots), 
app-snapshots (http://nexus.mycompany.com/content/repositories/app-snapshots, default, releases+snapshots)] and 'parent.relativePath' points at wrong local POM @ line 5, column 10

我在这里找到了一些有关在 settings.xml 文件中编辑镜像的答案。我在 /usr/share/maven/conf/settings.xml 中添加了阻塞的镜像： false

  <mirrors>
    <mirror>
      <id>app-releases</id>
      <mirrorOf>app-releases</mirrorOf>
      <url>http://nexus.mycompany.com/content/repositories/app-releases</url>
      <blocked>false</blocked>
    </mirror>
    <mirror>
      <id>app-snapshots</id>
      <mirrorOf>app-snapshots</mirrorOf>
      <url>http://nexus.mycompany.com/content/repositories/app-snapshots</url>
      <blocked>false</blocked>
    </mirror>
  </mirrors>

但仍然出现此错误，我不明白为什么它在 maven-default-http-blocker ( http://0.0.0.0/ ) 中搜索工件，而选项 -X (debug) 显示正在使用 settings.xml 文件，所以应该使用我设置的镜子。

1100 [DEBUG] Reading global settings from /usr/share/maven/conf/settings.xml
1100 [DEBUG] Reading user settings from /root/.m2/settings.xml

我在镜子定义中犯了错误吗？

Answer 1

这可能是由于 Maven 3.8.1 阻止了 http 存储库。

如果贵公司支持，我会切换到 https 存储库。

Answer 2

可以在本地做镜像。将其添加到~/.m2/settings.xml（这是特定于用户的<maven_dir>/conf/settings.xml.

<settings>
    <!-- if you need http connection, enable it and don't block -->
    <mirrors>
        <mirror>
          <id>maven-default-http-blocker</id>
          <mirrorOf>external:http:*</mirrorOf>
          <name>Pseudo repository to mirror external repositories initially using HTTP.</name>
          <url>http://0.0.0.0</url>
          <blocked>false</blocked>
        </mirror>
    </mirrors>
    ...
</settings>

我什至将网址更改为file:/home/<my_user>/.m2/repository，这解决了我的问题。
