如何在Android Studio 3.0.0中使用数据绑定和Kotlin
问题描述：
我刚开始使用Android Studio 3.0.0，但是每次尝试构建项目时，都会出现此错误:
I just started to use Android Studio 3.0.0, but every time I try to build my project I get this error:
Error:Circular dependency between the following tasks:
:app:compileDebugKotlin
+--- :app:dataBindingExportBuildInfoDebug
| \--- :app:compileDebugKotlin (*)
\--- :app:kaptDebugKotlin
\--- :app:dataBindingExportBuildInfoDebug (*)
(*) - details omitted (listed previously)
我正在使用
kapt "com.android.databinding:compiler:2.2.0"
在我使用
androidProcessor "com.android.databinding:compiler:2.2.0"
它工作得很好...我做错了什么?
And it was working just fine... What I am doing wrong??
谢谢！
答
似乎您需要在模块级别的应用程序.gradle中添加3个gradle条目以添加数据绑定
It seems that you need 3 gradle entries in the app .gradle at module level to add data binding
-
apply plugin: 'kotlin-kapt' -
android { ... dataBinding { enabled = true } } -
dependencies { ...... kapt "com.android.databinding:compiler:$compiler_version" }
apply plugin: 'kotlin-kapt'android { ... dataBinding { enabled = true } }dependencies { ...... kapt "com.android.databinding:compiler:$compiler_version" }
请注意，我在项目级别的构建gradle中将编译器版本作为变量，以便可以在单个位置进行管理
Notice that I made compiler version a variable in the project level build gradle so it can be managed from a single place
默认值为:ext.kotlin_version = '1.1.3-2'
我添加了括号语法:
ext{
kotlin_version = '1.1.3-2'
compiler_version = '3.0.0-beta6'
}
