我在Scala中有一个项目，试图将版本从Scala 2.12.3升级到2.12.13，但是该过程在我的CI管道中失败，并带有以下stacktrace：

The command "sbt clean coverage test coverageReport" exited with 1.
纯粹是兼容性错误，而sbt覆盖率是罪魁祸首。知道如何解决这个问题吗？
我们通常建议针对完整的Scala版本发布编译器插件。
在scala-compiler的两个补丁版本之间没有二进制兼容性保证。
这意味着即使补丁程序版本对于发布工件也很重要
a.b.c
^
例如，比较wartremover编译器插件如何包含补丁程序版本
wartremover_2.13.3/
wartremover_2.13.4/
wartremover_2.13.5/
scalac-scoverage-plugin_2.13/
Build CrossVersion.full＃306已解决此问题，scalac-scoverage-plugin但尚未发布。
