将 Android Studio 升级到 3.1.0 后的 Android Support 插件错误

Question

我在我的项目中使用 Kotlin 和数据绑定(bind)，最近升级到 Android Studio 3.1.0 后，我经常在 Android 支持插件中看到很多异常:

到目前为止，我已经尝试过:

使缓存无效并重新启动

重新导入项目

清理重建

没有以前的配置的全新安装 + 重新导入项目 + 没有安装额外的插件

在 gradle.properties 中用其中一个或全部注释掉每一行 + 无效并重新启动

试过implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8"在 gradle 中“以防万一”

没有任何帮助，几乎每个文件中仍然会弹出错误。正如我所看到的，这在某种程度上与绑定(bind)和 kotlin 有关。

有人遇到过这个问题吗？

附言

在布局 xml 文件中，甚至没有突出显示不存在的字符串资源，例如 @string/non_existing_title - 仅显示为有效的字符串资源(即使在全新安装之后)。
虽然我不确定这个问题是否与报告的异常有关。

我注意到在 Invalidate & restart 之后抛出另一个异常:

....

    at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
    ... 63 more

我尝试添加 javapoet 依赖项，但在失效后仍然会抛出此异常一次。然后只有 Could not initialize class android.databinding.tool.ext.ExtKt如最初报告的那样抛出异常。

Answer 1

经过一番犹豫，我决定转移到金丝雀 channel 并安装 Android Studio Canary 10(导入以前的设置)，现在规范是:

Android Studio 3.2 Canary 10 Build #AI-181.2784.17.32.4705630，于 2018 年 4 月 7 日构建
JRE:1.8.0_152-release-1136-b01 amd64
JVM:JetBrains s.r.o Linux 4.13.0-38-generic 的 OpenJDK 64 位服务器 VM

在安装时，我遇到了 kotlin 找不到很多类的多个问题；无效并重新启动，清理/重建没有帮助。

然后我刚刚从 卸载了 Kotlin 插件插件 部分，看起来重启后它恢复为原始版本，此后我没有任何问题。

当前 Kotlin 插件版本:版本:1.2.31-Studio3.2-1

最后一切都按预期工作。 @Yazazzello，感谢您对 Android Studio Canary #10 的反馈。
