初始化opendaylight架构时maven3.3.9的这个错误是什么？答案

【发布时间】：2017-04-20 08:00:31
【问题描述】：

我正在运行这个：

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

我得到了这个错误：

[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]

但我可以在网络上打开此链接（'http://nexus.opendaylight.org/content/repositories/opendaylight.snapshot/archetype-catalog.xml'）。

在我删除最后一个选项后：

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

没有错误，但结果不如预期。

那么如何在maven中使用“-DarchetypeCatalog=http://nexus.opendaylight.org/content/repositories/opendaylight.snapshot/archetype-catalog.xml”呢？

谢谢~

【问题讨论】：

希望你的 settings.xml 配置正确
能否粘贴您的setting.xml？

标签： java maven opendaylight

【解决方案1】：

如下图配置你的settings.xml，基本上我添加了ODL repo。

并且在archetypeCatalog 中您不提供URL，您需要提供远程、本地或内部，尽管它下面的可选是更新的mvn 命令。查看here 了解有关archetypeCatalog 参数的更多信息

mvn archetype:generate -DarchetypeGroupId=org.opendaylight.controller -DarchetypeArtifactId=opendaylight-startup-archetype -DarchetypeVersion=1.4.0-SNAPSHOT

【讨论】：

【解决方案2】：

尝试：

mvn archetype:generate -DarchetypeGroupId=org.opendaylight.controller
  -DarchetypeArtifactId=opendaylight-startup-archetype \
  -DarchetypeCatalog=remote \
  -DarchetypeVersion=<whatever your version is>

并使用名为 archetypes 的新 repository 调整您的 settings.xml 文件。我在阅读 Maven 文档时发现了这一点。抱歉，我手头没有确切的指针。

我担心 ODL 社区还没有更新他们的settings.xml，我们必须自己做。

【解决方案3】：

在构建项目时指定maven版本，如下：

mvn org.apache.maven.plugins:maven-archetype-plugin:3.0.0:generate \
-DarchetypeGroupId=org.opendaylight.controller -DarchetypeArtifactId=opendaylight-startup-archetype \
-DarchetypeRepository=https://nexus.opendaylight.org/content/repositories/public \
-DarchetypeCatalog=https://nexus.opendaylight.org/content/repositories/public/archetype-catalog.xml \
-DarchetypeVersion=1.2.2-Boron-SR2
