如何解决使用 kotlin 多平台编译 ios 项目时出错
我已经在现有的 ios 项目中实现了 kotlin 多平台,但我遇到了这些问题
当我为模拟器编译应用程序时,构建阶段脚本中出现错误。
Error: Could not find or load main class org.gradle.wrapper.GradleWrapperMain
Caused by: java.lang.ClassNotFoundException: org.gradle.wrapper.GradleWrapperMain
Command PhaseScriptExecution failed with a nonzero exit code
当我删除脚本时,为模拟器编译的脚本就可以工作了?。我可以运行模拟器
另一个错误是当我想归档项目时。说它是为 iOS 模拟器构建的?
我的 build.gradle.kts

解决方法
Another error is when I want to archive the project. Says it was built for iOS simulator ?
嗨。我遇到过几次这个问题,唯一的解决方法是我们需要在 android studio 终端中运行这个 ./gradlew clean
,然后再为 iOS 创建存档,然后尝试创建存档,它应该可以工作。您可以在此处找到更多详细信息:- https://youtrack.jetbrains.com/issue/KT-40907
When I compile the application for the simulator an error occurs in the build phases script.
为此,您的包装器似乎已损坏,可能对此不太确定。 android 应用程序运行完美吗?你也可以在这里看看:- How to resolve java.lang.ClassNotFoundException: org.gradle.wrapper.GradleWrapperMain error?
