Question

我有一个Spring Boot gradle项目etl，该项目在另一个名为common的项目中具有公共核心类的依赖关系。

etl项目和common项目在文件系统中位于同一级别。

问题是，每当我尝试构建依赖于etl的{{1}}项目时，它就会显示一些与我期望从{{1}引入并可用的类有关的问题。 }项目。

我已经使用common将common纳入了common项目的settings.gradle内，并且无法找到有关gradle多模块包含机制的任何问题。

这个扁平的多模块生态系统有什么问题？

构建脚本位于etl文件夹中的etl。

Answer 1

问题是由于includeFlat和./gradlew clean build项目中都存在spring boot插件。因此我发现必须在etl中添加以下代码：

common

Spring Boot多模块Gradle项目类路径问题：找不到包，找不到符号
