android - CircleCI 2.0 : Error unmarshaling return header; nested exception is:

Question

我已经创建了一些 Espresso UI 测试。测试在本地(模拟器和真实设备)运行良好。但是当我试图在 CircleCI 上运行 UI 测试时。我收到此错误日志

Task :app:compileFossDebugAndroidTestKotlin Compilation with Kotlin compile daemon was not successful java.rmi.UnmarshalException: Error unmarshaling return header; nested exception is:

编译后无法清除 jar 缓存，可能守护进程已经关闭:java.rmi.ConnectException: Connection refused to host: 127.0.0.1;嵌套异常是: java.net.ConnectException: 连接被拒绝 (Connection refused)无法连接到 kotlin 守护程序。使用回退策略。

选择 JAVA_TOOL_OPTIONS:-Xms512m

Task :app:compileFossDebugAndroidTestKotlin FAILED

失败:构建失败，出现异常。

• 出了什么问题:任务“:app:compileFossDebugAndroidTestKotlin”执行失败。

gradle.properties

其他配置

compileSdk version           : 28
targetSdk version            : 28
kotlin version               : '1.3.31'

该项目有两种风格:foss 和 play和 2 种构建类型:调试和发布

我已经尝试了所有可能的解决方案，但没有一个有效。任何帮助将不胜感激。谢谢

更新 config.yml 中的这一行帮助我避免了这个错误

GRADLE_OPTS: -Xmx1536m -XX:+HeapDumpOnOutOfMemoryError -Dorg.gradle.caching=true -Dorg.gradle.configureondemand=true -Dkotlin.compiler.execution.strategy=in-process -Dkotlin.incremental=false
