Question

今天，当我在构建程序时，遇到了一个问题。这个问题是：

FAILURE: Build failed with an exception.

 Where:
Build file 'C:\Users\Mert\Desktop\FireBase\platforms\android\build.gradle' line: 254

* What went wrong:
A problem occurred evaluating root project 'android'.
> Could not get unknown property 'GMS_VERSION' for object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

我的代码是：

dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
    // SUB-PROJECT DEPENDENCIES START
    debugCompile(project(path: "CordovaLib", configuration: "debug"))
    releaseCompile(project(path: "CordovaLib", configuration: "release"))
    compile "com.android.support:support-v4:24.1.1+"
    compile "com.google.android.gms:play-services-analytics:$GMS_VERSION"
    compile "com.android.support:support-v4:$ANDROID_SUPPORT_V4_VERSION"
    // SUB-PROJECT DEPENDENCIES END
}

如果您能回答这个问题，那对我来说将是完美的。

> Could not get unknown property 'GMS_VERSION' for object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

正如错误所暗示的，GMS_VERSION可能未在脚本中的任何地方声明。您应该声明GMS_VERSION变量，或者直接提及版本，而不要使用变量。

dependencies {
    def GMS_VERSION = "16.0.8"
    compile fileTree(dir: 'libs', include: '*.jar')
    // SUB-PROJECT DEPENDENCIES START
    debugCompile(project(path: "CordovaLib", configuration: "debug"))
    releaseCompile(project(path: "CordovaLib", configuration: "release"))
    compile "com.android.support:support-v4:24.1.1+"
    compile "com.google.android.gms:play-services-analytics:$GMS_VERSION"
    compile "com.android.support:support-v4:$ANDROID_SUPPORT_V4_VERSION"
    // SUB-PROJECT DEPENDENCIES END
}

或直接使用版本

compile "com.google.android.gms:play-services-analytics:16.0.8"
