添加库 Android-studio

Question

在我的项目中添加 achartengine-1.1.0.jar 时遇到问题。 当我添加

compile file('libs.achartengine-1.1.0.jar') 

在 build.gradle 中，Gradle 显示以下消息：

Gradle: A problem occurred evaluating project ':NativeCharts'.
Cannot convert the provided notation to an object of type Dependency: /home/***/NativeChartsProject/NativeCharts/libs/achartengine-1.1.0.jar.
  The following types/formats are supported:
    - Instances of Dependency.
    - Strings/CharSequences, e.g. 'org.gradle:gradle-core:1.0'.
    - Maps, e.g. [group: 'org.gradle', name: 'gradle-core', version: '1.0'].
    - FileCollections, e.g. files('some.jar', 'someOther.jar').
    - Projects, e.g. project(':some:project:path').
    - ClassPathNotation, e.g. gradleApi().
  Comprehensive documentation on dependency notations is available in DSL reference for DependencyHandler type.

提前致谢。 棒棒哒。

依赖项应该是compile files(...)，而不是compile file(...)。同样在上面您将路径写为libs.achartengine-1.1.0.jar，这应该是libs/achartengine-1.1.0.jar。
