Android studio编译失MalformedInputException: Input length = 1
问题描述
Android studio 无法正常编辑、编译代码，但是可以正常运行代码。
前提： jdk环境正常，SDK正常。
问题表现： build可能没有错误日志，代码可以正常运行。但是没有代码提示，无法正常显示不同代码的颜色，无法Ctrl+点击跳转，Android studio右下角显示感叹号（IDE error），异常如下：

或者build报如下警告
Deprecated Gradle features were used in this build, making it incompatible with Gradle 6.0.
Use '--warning-mode all' to show the individual deprecation warnings.
See https://docs.gradle.org/5.4.1/userguide/command_line_interface.html#sec:command_line_warnings
问题分析
问题关键字java.nio.charset.MalformedInputException: Input length = 1(并没啥鸟用,你搜不到正确答案的,网上都说这个是编码问题)，真正原因可能是你使用过高版本Gradle编译代码,当前使用的gradle版本低于历史版本导致的(因为gradle不能降级编译)。
解决方案
升级当前Gradle版本，如果不确定曾经使用的最高版本那便使用当前最高gradle版本（gradle官网历史版本）
