gradlew complie没有lib.jar

我正在使用gradle（gradle 4.7）编译一个项目（Java 1.8），该项目具有多模块：

./gradlew -p web -x test build

其中一个没有dist jar，其他的有，有什么问题吗？编译输出的正常dir结构：

--build
----classes
----libs
----tmp

以及异常的dir结构：

--build
----classes
----tmp

这是build.gradle（异常模块）：

PS:all模块不生成libs文件夹，libs是缓存。为什么模块不生成dis jar文件，如何配置我的gradle项目。这是我的项目的完整配置：

PS：我的问题是这样的备忘录：

---

我已经解决了这个问题，但不知道为什么……

为了解决这个问题，使用这个命令来构建项目（它将生成libs文件夹和jar文件）：

---

Gradle版本：4.7。（Gradle 5.3不工作）

要解决此问题，请使用此命令构建项目（它将生成libs文件夹和jar文件）：

渐变版本：4.7。（渐变5.3不工作）
