Could not write standard input to Gradle Test Executor x.问题解决记录

报错信息

最近系统的学了一些Kotlin进阶的东西，想在Android Studio 项目里的 unitTest写一写练练手，但是发现测试方法运行不起来，报错：

报错信息看的毫无头绪，只看得出来应该是文件读写有关，网上找了相关资料，最后在stackOverflow上终于解决了

解决方法：

项目的gradle.properties 配置文件内，找到 “org.gradle.jvmargs”， 如下：

org.gradle.jvmargs=-Xmx2048m -Dfile.encoding=UTF-8

将后面的编码配置信息删除，改为如下即可：

org.gradle.jvmargs=-Xmx2048m

-Dfile.encoding=UTF-8 这个配置我记得以前是没有的，可能是最近更新的Android Studio自动加上去的
