java - 多个存储库的 Maven 设置

Question

我在 settings.xml 中有以下内容

<mirrors>
       <mirror>
          <id>paid-jars</id>
          <name>jars with license</name>
          <url>http://url:8081/nexus/content/repositories/paidjars/</url>
          <mirrorOf>!central</mirrorOf>
      </mirror>
      <mirror>
          <id>Org-central</id>
          <name>mirror of central</name>
          <url>http://url:8081/nexus/content/repositories/central/</url>
          <mirrorOf>central</mirrorOf>
      </mirror>
  </mirrors>

在 pom.xml 我有两个 jar

1. apache-commons.jar(我假设是从中央下载的)
2. licensed.jar(我假设是从付费 jar 下载的)

但是当我运行 maven clean install 时，它会尝试从 Org-central 下载 license.jar。

如何让它使用付费 jar 下载？是否有可能首先进入 Org-central，如果失败，它会尝试付费 jar ？如果是这样，怎么做？我不想将 repo 条目放在 pom.xml 中

Answer 1

你必须设置镜像

<mirror>
  <id>nexus</id>
  <mirrorOf>*</mirrorOf>
  <url>http://internal/nexus/content/repositories/thirdparty</url>
</mirror>

 <mirror>
  <id>google</id>
  <mirrorOf>google</mirrorOf>
  <url>http://google-maven-repository.googlecode.com/svn/repository</url>
</mirror>   

然后添加内部和外部 repo

<profile>
     <id>nexus</id>
  <repositories>

    <repository>
      <id>central</id>
      <name>central</name>
      <url>http://internal/nexus/content/repositories/thirdparty</url>
    </repository>


    <repository>
      <id>google</id>
      <name>google</name>
      <url>http://google-maven-repository.googlecode.com/svn/repository</url>
    </repository>

  </repositories>
</profile>
