java - 在Eclipse中创建一个Maven项目提示 "Could not resolve archetype"

Question

这个问题在这里已经有了答案:

Failed to resolve version for org.apache.maven.archetypes (19 个回答)

关闭 6年前。

我完全是 Maven 的新手。我想用原型(prototype)为“webapp”的 Eclipse Juno EE 创建一个 Maven 项目。我安装了“Maven Integration for Eclipse WTP(孵化)”，我还安装了“Maven Integration for Eclipse”(在 Eclipse Marketplace 的已安装选项卡上找到它)。当我尝试从 File->New_>Maven Project 创建新项目时，出现错误:

Could not resolve archetype org.apache.maven.archetypes:maven-archetype-webapp:RELEASE from any of the configured repositories.Could not resolve artifact org.apache.maven.archetypes:maven-archetype-webapp:pom:RELEASEFailed to resolve version for org.apache.maven.archetypes:maven-archetype-webapp:pom:RELEASE: Could not find metadata org.apache.maven.archetypes:maven-archetype-webapp/maven-metadata.xml in local (C:\Documents and Settings\PEP35KD\.m2\repository)Failed to resolve version for org.apache.maven.archetypes:maven-archetype-webapp:pom:RELEASE: Could not find metadata org.apache.maven.archetypes:maven-archetype-webapp/maven-metadata.xml in local (C:\Documents and Settings\PEP35KD\.m2\repository)

It happens for all kinds of archetype.I am using a proxy, and I create file settings.xml under C:\Documents and Settings\PEP35KD.m2\ with this content:

<proxies>
    <proxy>
        <id>myId</id>
        <active>true</active>
        <protocol>http</protocol>
        <username>rete\pep35kd</username>
        <password>XXXX</password>
        <host>XXXX</host>
        <port>8080</port>
        <nonProxyHosts>localhost</nonProxyHosts>
    </proxy>
</proxies>

请考虑一下，我似乎无法从命令行使用 mvn 命令(找不到命令)。我从来没有安装过 Maven，我认为这个插件就足够了:这是一个正确的假设吗？

UPDATE 问题肯定与代理有关。作者:

• 在本地 PC 上安装 Maven；
• 从 Eclipse 安装 Maven Eclipse市场；
• 将 Maven 安装目录设置为本地 PC Maven 目录，而不是默认的 Embedded Maven，

一切都按预期进行。我真的不明白为什么，但可能是防火墙阻止了 Maven 服务器的流量。

Answer 1

我按照 this other StackOverflow question 的解决方案解决了这个问题。

I had the same problem. I fixed it by adding the maven archetype catalog to eclipse. Steps are provided below: (Please note the https protocol)

1. Open Window > Preferences
2. Open Maven > Archetypes
3. Click 'Add Remote Catalog' and add the following:
   • Catalog File: https://repo1.maven.org/maven2/archetype-catalog.xml
   • Description: maven catalog
