Gradle编译的Scala类与IntelliJ不兼容？(Compiled Scala classes by Gradle not compatible with IntelliJ?)

Gradle编译的Scala类与IntelliJ不兼容？(Compiled Scala classes by Gradle not compatible with IntelliJ?)

我有使用gradle配置的scala项目作为构建工具。 在开发过程中，我使用IntelliJ和已配置的Scala插件和Gradle插件。

我的问题是为什么gradle从命令行/终端编译的类与IntelliJ中的类不兼容（即IntelliJ总是尝试重新编译scala类，即使我不修改任何东西而只是运行测试）？

I have scala projects configured with gradle as build tool. During development, I use IntelliJ with configured Scala plugin and Gradle plugin.

My question is why classes compiled by gradle from command line/terminal is not compatible with the one from IntelliJ (i.e. IntelliJ always try to recompile scala classes even if I don't modify anything and just run the test)?

最满意答案

这是IntelliJ的已知错误，看起来不太可能修复。 问题是IntelliJ有一个增量编译器，并且很难将外部编译的类合并到其依赖图中，因为scalac编译器不会生成IntelliJ使用的自定义依赖图信息。

This is a known bug with IntelliJ which does not look like it is possible to fix. The issue is that IntelliJ has an incremental compiler, and it is very difficult to incorporate externally compiled classes into its dependency graph, because the scalac compiler doesn't produce the custom dependency graph info that IntelliJ uses.
