maven - 如何通过 https 在 maven 上获取 pom标签？

问题描述

我尝试通过源代码在我的电脑上安装 Apache Ignite 2.9.1（最新版本）。

我需要在其中运行

mvn clean install -Pall-java,all-scala,licenses -DskipTests

但是，有一个错误，我无法从 maven 存储库中获取 pom 文件。

这是因为maven已经把所有的http都转成https了，所以我应该使用 https://repo1.maven.org/maven2/org/apache/apache/16/apache-16.pom 而不是 http://repo1.maven.org/maven2/org/apache/apache/16/apache-16.pom

但是当我在 Ignite 文件夹中找到 pom.xml 时，我发现它是：

<parent>
        <groupId>org.apache</groupId>
        <artifactId>apache</artifactId>
        <version>16</version>
</parent>

我无法获取的 pom 文件由 <parent> 标记声明。

那么，我怎样才能转移 url 来下载这个 pom？另外，在一些老的maven项目中经常有很多http url(dependences, pom, ...)，有什么工具可以自动把这些http url转成https吗？

另外，我的 Maven 版本是 3.6.3，我的 {MAVEN_HOME}/conf/setting.xml 是

解决方案

看来这个问题已经部分回答了。很可能你有一个过时的 Maven 版本（< 3.2.3）。这就是为什么您的构建试图达到http://repo1.maven.org/maven2/. 查看描述此行为的文章。您的设置解决方法可能不起作用，因为http://repo1.maven.org/maven2/它曾经是 Maven 3.0.4 之前的默认设置，但您https://repo.maven.apache.org/maven2在settings.xml. 这是证实这一点的答案。据我了解，您有 3 个基本选项：

  • 将 Maven 更新到一些较新的版本 (3.2.3+)
  • 更改pom.xml以反映正确的端点
<repositories>
    <repository>
        <id>central</id>
        <url>https://repo1.maven.org/maven2/</url>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </repository>
</repositories>
<pluginRepositories>
    <pluginRepository>
        <id>central</id>
        <url>https://repo1.maven.org/maven2/</url>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </pluginRepository>
</pluginRepositories>
  • 修改settings.xml以包含适当的镜像
<mirrors>
    <mirror>
        <id>centralhttps</id>
        <mirrorOf>central</mirrorOf>
        <name>Maven central https</name>
        <url>https://repo1.maven.org/maven2/</url>
    </mirror>
</mirrors>
