有关构建要发布的应用程序的数据绑定问题

Question

我正在尝试在手机上运行发布模式的应用程序。 单击运行后，我的消息日志中充满以下错误：

Warning:android.databinding.DataBindingUtil: can't find referenced class android.databinding.DataBinderMapper
Warning:android.databinding.DataBindingUtil: can't find referenced class android.databinding.DataBindingComponent
Warning:android.databinding.ViewDataBinding: can't find referenced class android.databinding.DataBinderMapper

Warning:there were 46 unresolved references to classes or interfaces.
Warning:Exception while processing task java.io.IOException: Please correct the above warnings first.
Error:Execution failed for task ':app:transformClassesAndResourcesWithProguardForStageRelease'.
> Job failed, see logs for details

这是我的build.gradle的一部分

buildTypes {
        release {
            debuggable false
            minifyEnabled true
            zipAlignEnabled true
            shrinkResources true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            signingConfig signingConfigs.bom
            pseudoLocalesEnabled false
        }
        debug {
            debuggable true
        }
    }

在发行版本中插入dataBinding{enabled true } ，错误降至约3。

是否有一个原因？

由于ProGuard的警告，您的构建失败。 这些并不总是会阻塞，您可以在Proguard中添加-dontwarn行来绕开它们。 最好的办法是找到受影响代码所在的库，并从库中找到可以安全添加哪些ProGuard规则的文档。
