执行 Maven archetype generate 命令创建 Opendaylight 项目结构时出错

Question

当我执行此操作时：

 mvn archetype:generate -DarchetypeGroupId=org.opendaylight.controller -DarchetypeArtifactId=opendaylight-startup-archetype \
-DarchetypeRepository=http://nexus.opendaylight.org/content/repositories/opendaylight.snapshot/ \
-DarchetypeCatalog=http://nexus.opendaylight.org/content/repositories/opendaylight.snapshot/archetype-catalog.xml

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://nexus.opendaylight.org/content/repositories/opendaylight.snapshot/archetype-catalog.xml' is not supported anymore. Please read the plugin documentation for details. -> [Help 1]

help1 看起来像这样：

[ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/MojoFailureException

好久没更新了

首先，我删除了反斜杠和空格，显然它没有用。我以为可能是archetypeCatalog的参数，所以我运行这个：

mvn archetype:generate -DarchetypeGroupId=org.opendaylight.controller -DarchetypeArtifactId=opendaylight-startup-archetype -DarchetypeCatalog=remote -DarchetypeVersion=1.1.2-Beryllium-SR2

我收到这样的错误：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-archetype-plugin:3.0.1:generate (default-cli) on project standalone-pom: The desired archetype does not exist (org.opendaylight.controller:opendaylight-startup-archetype:1.1.2-Beryllium-SR2) -> [Help 1]

本教程提到 OpenDaylight 在 Maven Central 之外维护自己的存储库，这意味着默认情况下 maven 无法解析 OpenDaylight 工件。所以我按照以下命令做了教程：

cp -n ~/.m2/settings.xml{,.orig} ; \ wget -q -O - https://raw.githubusercontent.com/opendaylight/odlparent/master/settings.xml > ~/.m2/settings.xml

我什至试过这个：

cp -n ~/.m2/settings.xml{,.orig} ; \ wget -q -O - https://raw.githubusercontent.com/opendaylight/odlparent/stable/beryllium/settings.xml > ~/.m2/settings.xml

settings.xml 文件看起来一样。这些天我看到了一些类似的问题。作为 maven 和 opendaylight 的新手，我不知道下一步该做什么？我只想生成一个 opendaylight 原型来启动烤面包机。

感谢您的帮助。这是我的行家信息：

 ➜  ~ mvn -v
Apache Maven 3.5.0 (ff8f5e7444045639af65f6095c62210b5713f426; 2017-04-04T03:39:06+08:00)

Answer 1

使用 maven-archetype-plugin 3.x 不再可能将存储库指定为命令行参数（出于一致性和安全原因）。

所以你有两个选择：

关注the new instructions
将插件版本锁定为2.4

Answer 2

自 Maven Archetype Plugin 3.0.0 起，原型解析已更改。不再可能通过命令行指定存储库，而是使用已经为 Maven 指定的存储库。这意味着还尊重镜像和代理，以及对存储库的身份验证。 1.You 将删除 -DarchetypeCatalog & -DarchetypeRepository 2. 在你的.m2/setting.xml中添加

  <settings>
    <mirrors>
      <mirror>
        <id>mrm-maven-plugin</id>
        <name>Mock Repository Manager</name>
        <url>http://www.mycompany.com/maven-reporistory-manager</url>
        <mirrorOf>*,!archetype</mirrorOf>
      </mirror>
    </mirrors>

    <profiles>
      <profile>
      <id>acme</id>
      <repositories>
        <repository>

          <url>https://www.acme.com/repo</url>
          <releases>
            <enabled>true</enabled>
            <checksumPolicy>fail</checksumPolicy>
          </releases>
          <snapshots>
            <enabled>true</enabled>
            <checksumPolicy>warn</checksumPolicy>
          </snapshots>
        </repository>
      </repositories>
    </profile>
  </profiles>

  <activeProfiles>
    <activeProfile>acme</activeProfile>
  </activeProfiles>
</settings>

看看http://maven.apache.org/archetype/maven-archetype-plugin/archetype-repository.html

Answer 3

添加一个 id 为 archetype 的仓库：

  <repository>
    <id>archetype</id>
    <url>https://repository.domain.com/path/to/repo/</url>
  </repository>

就我而言，

  <repository>
     <id>archetype</id>
     <url>http://nexus.opendaylight.org/content/repositories/opendaylight.snapshot/</url>
  </repository>

基本上，我是不带-DarchetypeRepository 参数执行的，但是把它放在上面的settings.xml中。并将 -Darchetypecatalog 参数更改为 remote 或将其设置为空。有效。

Answer 4

最近的 Maven 版本不支持原型的命令行定义。因此，简而言之，您的默认设置文件应如下所示 (vi ~/.m2/setting.xml),

<?xml version="1.0" encoding="UTF-8"?>

Answer 5

如果您是因为在创建 Ninja 项目时收到此错误消息而来到这里，请下载最新版本的 Maven。（高于 2.5.2 的任何版本）。

此错误发生在低于 2.5.3 的 Apache Maven 版本

Answer 6

在使用 archetype Catalog 生成项目时指定特定的 maven archtype 插件版本（版本低于 3.x）

mvn org.apache.maven.plugins:maven-archetype-plugin:2.4:generate -DarchetypeCatalog=<archetype-url>
