Gradle多模块项目构建问题

Question

我有一个具有以下结构的多模块项目

当我尝试构建信号站点项目时，出现此异常

Caused by: org.gradle.api.internal.artifacts.ivyservice.DefaultLenientConfiguration$ArtifactResolveException: Could not resolve all task dependencies for configuration ':runtimeClasspath'.

settings.gradle.kts（交易）-顶级

rootProject.name = "trade"
include("trade-common")
include("signal-site")

build.gradle.kts（交易）-顶级

group = "com.oleinikdi"
version = "1.0"

subprojects {
    version = "1.0"
}

    }
}

在多项目构建中，项目的根目录必须只有一个 settings.gradle文件。

因此，您的问题是由在层次结构中定义了多个settings.gradle引起的，这意味着在signal-site中运行某些内容时，Gradle被配置为将trade-common查找为{{ 1}}。

只需删除signal-site和trade-common signal-site文件，仅在根目录下保留一个即可。

请参阅the documentation，以更深入地了解Gradle settings.gradle文件及其在多项目设置中的工作方式。
