android studio 导入jar无效,Android Studio导入jar时遇到的问题

首先贴上Log:

Error:(25, 0) Cannot convert the provided notation to an object of type Dependency: /HomePath/workspaceAppProject/WeatherWebService/app/libs/ksoap2-android-assembly-3.4.0-jar-with-dependencies.jar.

The following types/formats are supported:

- Instances of Dependency.

- String or CharSequence values, 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.

出现了这个错误难免，我们看看Module的build.gradle文件下dependencies这个节点是如何写的：

dependencies {

compile fileTree(dir: 'libs', include: ['*.jar'])

compile 'com.android.support:appcompat-v7:22.0.0'

compile file('libs.ksoap2-android-assembly-3.4.0.jar')

}

在google了一通之后，找到了如下答案：

The dependency should read "compile files(...)", not "compile file(...)".

Also in the above you write the path as 'libs.achartengine-1.1.0.jar', this should be 'libs/achartengine-1.1.0.jar'

所以正确的写法应该是：

compile files('libs/ksoap2-android-assembly-3.4.0.jar')
