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 …

我必须构建一个方法来添加参数中给出的字符串的每个数字,直到只剩下1位数,例如1234 = (1+2+3+4) = 10 = (1+0) = 1.

起初,我认为递归调用或while循环应该没问题.但有更聪明的方法吗？也许使用模数？

1234 % 9 = 1这似乎有效...但不是:9%9不等于,9但它是0.

有没有办法在没有递归/ for/while的情况下构建这个函数？
