java src 路径在 pom.xml 而有多个模块

Question

我有一个包含以下 pom.xml 文件的双模块项目，但 intellij idea 未检测到 java 文件并将它们视为一般文件，我哪里出错了？

模块-a 的 pom 文件是

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Answer 1

默认源目录为 src/main/java。在您的情况下，每个模块中只有 src。

您可以在每个模块的 pom 文件中包含以下行。

<sourceDirectory>${project.build.directory}/src</sourceDirectory>

或者您可以尝试将每个 src 目录标记为源目录。
