添加庫Android-studio

Question

當我在項目中添加achartengine-1.1.0.jar時遇到了問題。 當我在的build.gradle添加

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

，搖籃顯示以下消息：

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. 

預先感謝。 Fab。

相關性應該爲compile files(...)，而不是compile file(...)。同樣在上面你寫道libs.achartengine-1.1.0.jar，這應該是libs/achartengine-1.1.0.jar。
