Unable to load class ‘org.jetbrains.kotlin.gradle.plugin.mpp.pm20.KotlinCompilationData‘_unable to load class 'org.jetbrains.kotlin.gradle.

1、异常信息

使用ksp时，构建程序发生错误：

Unable to load class 'org.jetbrains.kotlin.gradle.plugin.mpp.pm20.KotlinCompilationData'.

2、分析流程

根据Android Developer 的建议使用ksp，发生了上面的错误。排除了语法等基础错误，清理再编译等方法都不可行。这时，到ksp介绍发现也新版本1.9.0-1.0.11，而我使用的kotlin版本也是1.9.0，所以，可能是版本的原因，修改正常版本，gradle 构建成功。

3、所得

在构建时排除了很多原因，还是无法解决时，那么可能是版本不兼容的原因。
