Maven:没有可编译的源代码 [英] Maven: No sources to compile

问题描述

我正在关注使用 Maven 构建 Java 项目"(https://spring.io/guides/gs/maven/#scratch) 并且当我从/Users/Misha/Desktop/src/main/java/hello 运行 'mvn compile' 时，我得到这个提示:

I am following the 'Build Java Projects with Maven' (https://spring.io/guides/gs/maven/#scratch) and when I run 'mvn compile' from /Users/Misha/Desktop/src/main/java/hello, I get this prompt:

我在 hello 目录中有两个 java 文件和 xml 文件，我假设我应该看到Hello World！"而不是没有要编译的来源.为什么我的java代码没有编译?谢谢！

I have the two java files and the xml file in the hello directory, and I am assuming that I should see "Hello World!" instead of No sources to compile. Why is my java code not compiling? Thanks!

推荐答案

要创建一个你需要的 Maven 项目

To create a maven-project you need

1. 包含 pom.xml-file 的项目目录
2. 在此项目目录中的子目录 src/main/java 包含您的 java 代码(包转到 src/main/java 的子目录)

1. A project-directory containing the pom.xml-file
2. Within this project-directory a subdirectory src/main/java containing your java-code (packages go to subdirectories of src/main/java)

从项目目录中调用 maven run mvn compile 或类似的东西.

To invoke maven run mvn compile or something similar from the project-directory.
