项目etl
和common
项目在文件系统中处于同一级别。
问题是,每当我尝试构建etl
依赖于 的项目时common
,它都会显示一些关于我期望从common
项目中获得并可用的类的问题。
我已经使用 using 将其包含在common
内部settings.gradle
项目etl
中,includeFlat
并且无法跟踪有关 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./gradlew clean build
位于 etl 文件夹中。
解决方案
etl
问题是因为和common
项目中都存在 spring boot 插件。所以我发现在cammon/build.gradle
我必须添加这段代码:
...
bootJar {
enabled = false
}
jar {
enabled = true
}
...
