Android Studio:“无法获得类型为org.gradle.api.Project的项目的未知属性'VERSION_NAME'"； [英] Android Studio : "Could not get unknown property 'VERSION_NAME' for project of type org.gradle.api.Project"

问题描述

我是Android Studio的新手.我正在尝试使用此项目库:在我的 https://github.com/2dxgujun/AndroidTagGroup 项目.

I am a newbie with Android Studio. I am trying to use this project library : https://github.com/2dxgujun/AndroidTagGroup in my project.

所以我要做的是将其作为模块导入我的项目中；名称为"androidtaggroup"

So what I did is to import it as a module in my project ; with the name "androidtaggroup"

现在，我在编译时遇到以下错误:

Now, I have got the following error at compilation:

"Could not get unknown property 'VERSION_NAME' for project ':androidtaggroup' of type org.gradle.api.Project."

在此处是Gradle文件中出现问题的地方:

Here is where the problem occurs in the Gradle file:

 defaultConfig {
        applicationId 'me.gujun.android.taggroup.demo'
        minSdkVersion 8
        targetSdkVersion 21
        versionName project.VERSION_NAME // ERROR HERE !!!!
        versionCode Integer.parseInt(project.VERSION_CODE)
    }

任何人都可以告诉我如何解决此问题吗?

Anybody can tell me how to fix this problem ?

谢谢!!!

推荐答案

解决方法是在此处定义您的版本名称或使用自定义变量. project.VERSION_NAME默认情况下不存在，因此您不能使用它.这基本上就是错误消息告诉您的内容.

The fix is to define your version name there or use a custom made variable. project.VERSION_NAME does not exists by default, therefore you can't use it. That is basically what the error message is telling you.

defaultConfig {
    applicationId 'me.gujun.android.taggroup.demo'
    minSdkVersion 8
    targetSdkVersion 21
    versionName "1.2.3"
    versionCode Integer.parseInt(project.VERSION_CODE)
}

或替代方法:

// somewhere above
def VERSION_NAME = "1.2.3"

// and the usage:
defaultConfig {
    applicationId 'me.gujun.android.taggroup.demo'
    minSdkVersion 8
    targetSdkVersion 21
    versionName VERSION_NAME
    versionCode Integer.parseInt(project.VERSION_CODE)
}

更改后，使用project.VERSION_CODE可能会遇到相同的问题:

And after you have changed that you will probably run into the same issue for using project.VERSION_CODE:

versionCode Integer.parseInt(project.VERSION_CODE)

修复相同:提供有效的自定义变量或常量

Fix is the same: provide a valid self defined variable or constant
