Java 的 AWS 开发工具包入门

Question

我对 Java 的 AWS SDK 还很陌生。我正在尝试按照此处的文档 (https://docs.aws.amazon.com/sdk-for-java/latest/developer-guide/get-started.html#get-started-projectsetup)

开始使用适用于 Java 2.x 的 AWS SDK

但是当我尝试使用以下命令创建此处提到的项目时

mvn -B archetype:generate \-DarchetypeGroupId=org.apache.maven.archetypes \-DgroupId=com.example.myapp \-DartifactId=myapp

我遇到一个错误：

PS C:\Users\robert\Desktop> mvn -B archetype:generate -DarchetypeGroupId=org.apache.maven.archetypes -DgroupId=com.example.myapp -DartifactId=myapp

如何创建maven项目并开始使用aws sdk？

Answer 1

命令中有 / 字符吗？如果是这样，你需要使用这个命令：

   mvn -B archetype:generate -DarchetypeGroupId=org.apache.maven.archetypes -DgroupId=com.example.myapp -DartifactId=myapp

我正在使用 JDK 1.8，此命令成功。

Answer 2

在 Powershell 中，您不能在命令行参数中使用句点（点或句号）。该页面上的说明缺少此信息，并假设是类 Unix 环境或 cmd 环境。你应该运行:

mvn -B archetype:generate "-DarchetypeGroupId=org.apache.maven.archetypes" "-DgroupId=com.example.myapp" -DartifactId=myapp
