Question

我正在尝试使用基本的Flink快速入门示例。

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

我在Maven的第一步遇到错误。无论我是否尝试使用Maven或“curl”命令进行安装，我都会收到相同的错误“已定义的工件不是原型”：

命令：

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

响应：

我很困惑，因为我上周能够毫无问题地执行这些快速入门，而且我对Maven / Flink完全不熟悉，所以我很难确定从那时起可能发生的变化。有什么想法吗？

Answer 1

仅定义原型是不够的。您还需要提供当前maven项目本身的详细信息。

当您运行上述命令时，您必须在交互模式下传递'groupId'，'artifactId'和'version'。
或者，您可以使用以下命令mvn archetype:generate -DarchetypeGroupId=org.apache.flink -DarchetypeArtifactId=flink-quickstart-java -DarchetypeVersion=1.2.0 -DgroupId=com.example -DartifactId=flink -Dversion=0.1

Apache Quickstart无法正常工作：“已定义的工件不是原型”
