为什么我的 Maven 指向旧的中央存储库 url？

Question

我在通过 Maven 安装下载依赖项 jar 时遇到问题。

从 Eclipse 控制台，我可以说 maven 正在尝试从旧的中央存储库 url 下载 jar：“ https://repo.maven.apache.org/maven2 ”而不是“ http://repo1.maven.org/maven2/ ”

我的 pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.xxxx</groupId>
  <artifactId>TestServices</artifactId>
  <version>7.0.3.6</version>
  <dependencies>
    <dependency>
        <groupId>javax.activation</groupId>
        <artifactId>activation</artifactId>
        <version>1.0.2</version>
        <scope>compile</scope>
    </dependency>
  </dependencies>

我的构建失败并出现以下错误消息：

[ERROR] Failed to execute goal on project 'xxxyyy': Could not resolve dependencies for project xxxyyy:jar:4.0.3.6: The following artifacts could not be resolved: org.codehaus:xstream:jar:1.3.1, gxs:ai:jar:0.5, javax.activation:activation:jar:1.0.2, com.oracle.jdbc:classes12:jar:9.2.0.5, org.eclipse.core:resources:jar:3.1.0, org.eclipse.core:runtime:jar:3.2.0.v20060603, org.eclipse.emf:common:jar:2.2.1.v200609210005, org.eclipse.emf:ecore:jar:2.2.1.v200609210005, org.eclipse.emf:ecore.xmi:jar:2.2.1.v200609210005, org.eclipse.equinox:common:jar:3.2.0.v20060603, org.eclipse:osgi:jar:3.2.1.R32x_v20060919, org.eclipse.wst.xml:core:jar:1.1.1.v200609210600, org.eclipse:xsd:jar:2.2.1.v200609210005, javax.mail:mail:jar:1.3.2, org.apache:log4j:jar:1.2.8: Failure to find org.codehaus:xstream:jar:1.3.1 in ${localRepo} was cached in the local repository, resolution will not be reattempted until the update interval of 'abcd' has elapsed or updates are forced -> [Help 1]

Answer 1

尝试添加这个

 <repositories>
    <repository>
        <id>central</id>
        <url>https://repo1.maven.org/maven2/</url>
      </repository>
  </repositories>

并检查Maven 存储库的文档

并遵循文档：

存储库

存储库是 Maven 社区最强大的功能之一。默认的中央 Maven 存储库位于 https://repo.maven.apache.org/maven2/。iBiblio 中尚未包含的工件的另一个来源是 Codehaus snapshots 存储库。
