SBT scala 项目中的错误符号引用 [英] Bad symbolic reference in SBT scala project

问题描述

我做了一个小的重构，一切在语法上仍然是正确的，它应该可以编译.但是，我遇到了一个错误:

I did a small refactoring, everything is still syntactically correct and it should compile for sure. However, I got an error:

[error] bad symbolic reference. A signature in MyClass123.class refers to type MyClass456
[error] in package com.mypackage which is not available.
[error] It may be completely missing from the current classpath, or the version on
[error] the classpath might be incompatible with the version used when compiling MyClass123.class.
[error] one error found

我没有改变其他任何东西.我什至将代码恢复到以前的未重构版本，但错误仍然存​​在.我也尝试重新加载 sbt.

I didn't change anything else. I even revert code to the previous, unrefactored version but the error remains. I tried to reload sbt also.

也许我需要以某种方式从 sbt 生成的文件中清除项目?如果没有，我该怎么办?

Maybe I need to clean the project from sbt generated files somehow? If not, what do I do?

推荐答案

我最好的猜测是您确实需要清理项目.只需输入 sbt clean.

My best guess is that you need, indeed, clean the project. Just type sbt clean.
