一、implementation fileTree 引入目录下的文件作为依赖

org.gradle.api.Project 配置 ( build.gradle 根配置 ) 文档 : https://docs.gradle.org/current/javadoc/org/gradle/api/Project.html

在 build.gradle#dependencies 配置中 , 使用 implementation fileTree 引入文件树 , 将当前目录中 libs 目录下的所有 .jar 后缀的文件添加到依赖中 ;

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
}

fileTree 函数原型定义在 org.gradle.api.Project 配置中 , 在 Project 中提供了 4 4 4 种重载方法 ;

ConfigurableFileTree	fileTree​(Object baseDir)	
Creates a new ConfigurableFileTree using the given base directory.

ConfigurableFileTree	fileTree​(Object baseDir, Closure configureClosure)	
Creates a new ConfigurableFileTree using the given base directory.

ConfigurableFileTree	fileTree​(Object baseDir, Action configureAction)	
Creates a new ConfigurableFileTree using the given base directory.

ConfigurableFileTree	fileTree​(Map args)	
Creates a new ConfigurableFileTree using the provided map of arguments.

文档位置 : https://docs.gradle.org/current/javadoc/org/gradle/api/Project.html#fileTree-java.lang.Object-

二、implementation files 引入目录下的文件作为依赖

org.gradle.api.Project 配置 ( build.gradle 根配置 ) 文档 : https://docs.gradle.org/current/javadoc/org/gradle/api/Project.html

在 build.gradle#dependencies 配置中 , 使用 implementation files 引入多个文件 , 将这些文件添加到依赖中 ;

dependencies {
    implementation files('libs/ffmpeg.jar', 'libs/location.jar')
}

files 函数原型定义在 org.gradle.api.Project 配置中 , 在 Project 中提供了 3 3 3 种重载方法 ;

注意 file 函数只能指定一个文件 ;

File	file​(Object path)	
Resolves a file path relative to the project directory of this project.

File	file​(Object path, PathValidation validation)	
Resolves a file path relative to the project directory of this project and validates it using the given scheme.

ConfigurableFileCollection	files​(Object... paths)	
Returns a ConfigurableFileCollection containing the given files.

ConfigurableFileCollection	files​(Object paths, Closure configureClosure)	
Creates a new ConfigurableFileCollection using the given paths.

ConfigurableFileCollection	files​(Object paths, Action configureAction)	
Creates a new ConfigurableFileCollection using the given paths.
