Question

我正在尝试Maven in 5 Minutes教程，几乎立即遇到错误。 mvn --version的结果是

Apache Maven 3.5.2
Maven home: /usr/share/maven
Java version: 1.8.0_171, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-8-openjdk-amd64/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "4.15.0-23-generic", arch: "amd64", family: "unix"

当我在教程中运行下一个命令时，

$ mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app \
   -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

我收到以下错误：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-archetype-plugin:3.0.1:generate (default-cli)
on project standalone-pom: archetypeCatalog 'http://mavenrepo.openmrs.org/nexus/content/repositories/public/archetype-catalog.xml'
is not supported anymore. Please read the plugin documentation for details. -> [Help 1]

“帮助1”仅是docs for MojoFailureException。

似乎原型插件发布了一项重大更改，而Maven教程尚未更新以反映这一点。尽管有趣的是，docs for the Quickstart Archetype建议的命令，

$ mvn archetype:generate -DarchetypeGroupId=org.apache.maven.archetypes -DarchetypeArtifactId=maven-archetype-quickstart -DarchetypeVersion=1.3

也因相同的错误而失败。

是否仍然可以基于Quickstart原型生成Maven项目，如果可以，我该怎么做？

编辑：这是我的~/.m2/settings.xml文件：

Answer 1

实际上，由于错误消息的建议，不建议使用archetypeCatalog。您必须从archetypeRepository中删除属性archetypeCatalog和settings.xml，并声明一个archetype为id的存储库，如下所示：

<settings>
    <profile>
        <id>openmrs</id>
        <repositories>
            <repository>
                <id>archetype</id>
                <url>http://mavenrepo.openmrs.org/nexus/content/repositories/public</url>
            </repository>
            <!-- keep other repositories -->
        </repositories>
    </profile>
</settings>

您的活动配置文件是openmrs，因此应使用此配置来查找原型，因为它们存在于openmrs存储库中（请参见https://mavenrepo.openmrs.org/nexus/content/repositories/public/org/apache/maven/archetypes/）。
