android - 无法为类型为 org.gradle.api.Project 的项目 'file' 获取未知属性 ':app'

Question

我的音乐流媒体应用程序的应用程序项目中不断出现此错误:

Could not get unknown property 'file' for project ':app' of type org.gradle.api.Project.

我想知道我做错了什么。无论我尝试什么，我都会卡住。

这是来自 Android Studio 的应用项目。

Answer 1

App: Could not get unknown property 'file' for project ':app' of type org.gradle.api.Project.

问题出在这一行:

def initFabricPropertiesIfNeeded() {
    def propertiesFile = file
    //....
}

您可以查看 official doc .

The Project.file(java.lang.Object) method is used to create a file or directory path relative to the current project and is a common way to make build scripts work regardless of the project path.

你必须像这样改变你的脚本:

def propertiesFile = file('myFile.properties')

(可能是，但我不确定 def propertiesFile = file('fabric.properties'))
