无法生成视图活页夹 java.lang.NullPointerException答案

【问题标题】：cannot generate view binders java.lang.NullPointerException无法生成视图活页夹 java.lang.NullPointerException
【发布时间】：2018-03-23 05:30:05
【问题描述】：

突然我在重建项目时遇到了这个错误。有人有这方面的经验吗？在我的项目中，我使用Kotlin 1.1.51 和Data Binding

Error:error: cannot generate view binders java.lang.NullPointerException Error:java.lang.RuntimeException: failure, see logs for details. Error:org.gradle.api.GradleException: Internal compiler error. See log for more details

谁对我的问题投了反对票，请看下图。这是 Android Studio 构建错误，不是我的错误代码导致的异常

这是 Gradle 控制台消息：

* What went wrong:
Execution failed for task ':app:kaptProductionReleaseKotlin'.
> Internal compiler error. See log for more details

【问题讨论】：

不，不是。这不是来自我的代码，它与 Project Config 或 Kotlin Extensions 相关
您查看日志了解更多详情吗？
@nhaarman 请查看我刚刚附加的 Gradle 日志
我会说它是 Android 编译器中的一个错误。尝试尽可能多地剥离（最好是最多 3 个文件的项目），这样它仍然会导致 NPE，并在 issuetracker.google.com 上提交问题。

标签： android data-binding kotlin

【解决方案1】：

这似乎令人难以置信，但我想我找到了这个问题的根本原因。当我在最新版本的 Layer Atlas implementation 'com.layer.atlas:layer-atlas:0.4.17'987654321@ 中同步我的 gradle 时，Android Studio 不断抛出这个问题

如果我降级到以前的版本：implementation 'com.layer.atlas:layer-atlas:0.4.16'，它可以工作。

我已经多次尝试在这些版本之间切换，我认为我在这方面是正确的。

【解决方案2】：

我也遇到了随机库的问题。如果我更新或删除了库，则会抛出无法生成视图绑定器 java.lang.NullPointerException。值得庆幸的是，该错误很有帮助且具有描述性。

所以在尝试了一切之后。

更新到数据绑定库的第 2 版终于成功了，并且可以更新或删除该库。

要使用版本 2 的数据绑定，请使用正常的数据绑定设置，并将这一行添加到 gradle.properties 文件中。

android.databinding.enableV2=true
