Apache快速啓動不起作用：「定義的工件不是原型」

Question

我正試着開始使用基本的Flink快速入門示例。

https://ci.apache.org/projects/flink/flink-docs-release-1.2/quickstart/java_api_quickstart.html

我在與Maven的第一步得到一個錯誤。不管我是否嘗試使用Maven的安裝或「捲曲」的命令，我得到了同樣的錯誤「的定義神器不是一個原型」：

命令：

mvn archetype:generate        \ 
>  -DarchetypeGroupId=org.apache.flink    \ 
>  -DarchetypeArtifactId=flink-quickstart-java  \ 
>  -DarchetypeVersion=1.2.0 

響應：

我很困惑，因爲上週我能夠毫無問題地執行這些快速入門程序，而且我對Maven/Flink完全陌生，所以我無法確定自那時以來可能發生的變化。有任何想法嗎？

只定義原型是不夠的。您還需要提供當前Maven項目本身的詳細信息。

• 當您運行上述命令時，您必須在交互模式下傳遞'groupId'，'artifactId'和'version'。
• 或者，你可以使用下面的命令mvn archetype:generate -DarchetypeGroupId=org.apache.flink -DarchetypeArtifactId=flink-quickstart-java -DarchetypeVersion=1.2.0 -DgroupId=com.example -DartifactId=flink -Dversion=0.1
