"Maven in 5分钟“教程中的原型插件错误

Question

我正在尝试5分钟内教程，并且几乎立即遇到了一个错误。mvn --version的结果如下

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"

当我运行教程中的下一个命令时，

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

我得到以下错误：

[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]

其中“帮助1”只是MojoFailureException文档。

看起来，原型插件发布了一个突破性的变化，而且Maven教程还没有被更新以反映这一点。但有趣的是，Quickstart原型的文档建议的命令，

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

同样的错误也会失败。

是否仍然可以基于Quickstart原型生成maven项目，如果可以，我如何实现？

编辑:这是我的~/.m2/settings.xml文件：

Answer 1

实际上，正如错误消息所建议的那样，不推荐使用archetypeCatalog。您必须将属性archetypeRepository和archetypeCatalog从settings.xml中删除，并使用archetype声明存储库为id，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，因此应该使用此配置找到原型，因为它们存在于openmrs存储库中(参见https://mavenrepo.openmrs.org/nexus/content/repositories/public/org/apache/maven/archetypes/)。
