我正在为我们的项目编写一个kotlin库。完成后，我构建了一个.aar文件并将其发送给团队。但他们有一个错误，即"Module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.5.1, expected version is 1.1.16"(当时库的核心ktx版本是1.3.2，kotlin-gradle插件版本是1.5.0(。
我研究了一下，发现了这个线索。"模块是使用不兼容的Kotlin版本编译的。其元数据的二进制版本为1.5.1，预期版本为1.1.16"；
我在这里尝试了给定的解决方案，但到目前为止都不起作用。每当我使用低于1.5版本的kotlin-gradle插件时，我都会看到类似Runtime JAR files in the classpath have the version 1.4, which is older than the API version 1.5?的错误
我在这里共享gradle文件。

以下是我需要实现库的项目依赖项的版本(它们在一个文本文件中，所以我从那里复制(：
minSdkVersion: 21
targetSdkVersion: 30
compileSdkVersion: 30
appCompatVersion: "1.0.0"
gradleVersion : "3.3.0"
kotlinVersion: "1.3.60"
coreKtxVersion: "1.0.2"
有什么建议吗？
在build.gradle中更新它对我很有效(在根级别build.gradle中，而不是在app/build.gradle(
buildscript {
ext.kotlin_version = '1.6.0'
如果您使用较新版本的Kotlin(例如1.8.10(创建库，并且希望该库在使用较旧版本的Kodlin(例如1.5.0(的项目中工作，则需要设置languageVersion和apiVersion:
compileKotlin {
kotlinOptions {
jvmTarget = '1.8'
languageVersion = '1.4'
apiVersion = '1.4'
}
}
请记住，版本越低，可以在库的源代码中使用的Kotlin新功能就越少。
