升级Room引发的惨案！！

kotlin升级

在升级kotlin的时候，直接升级到大版本的kotlin（比如1.7以上），直接报错，只是报错不知道原因。
koltin Release details
后来把koltin版本改成1.6.0，报如下的错，我们才知道gradle是需要先升级的

所以升级kotlin版本有问题，可以换一个别的kotlin版本试试
在这里插入图片描述
gradle升级也是一堆坑，我一开始想升级到比较新的版本7.3.3
Android Gradle 插件版本说明

可以在 Android Studio 的 File > Project Structure > Project 菜单中指定插件版本
在这里插入图片描述
但是，升级到最新版本报各种错，而且语法也变了。

7.3.3是gradle的版本，是gradle-wrapper中配置的，7.2.1是gradle的插件版本，这两个得匹配才行，在上面的文章中有对应说明。
gradle插件是配置在这儿的在这里插入图片描述
后来妥协了，只要6.1.1以上就行
gradle是6.3，gradle插件是4.0.1

kotlin 1.6.0 会在kaptGenerateStubDebugKolin卡住

不知道为什么，把kotlin版本换成了1.6.10正常了

gradle 升级过程中有个报错

gradle是6.3，gradle插件是4.0.1

没有这个问题

这个意思是，library被打成aar包，里面放的aar包不会被打进最终的aar包里面，这个应该是gradle版本不同导致的，之前没升级gradle之前没事。
修改办法，在library中如下修改

-    implementation files('libs/vivo_pushSDK_v3.0.0.4_484.aar')
-    implementation files('libs/com.heytap.msp.aar')
+
+    compileOnly(name: 'vivo_pushSDK_v3.0.0.4_484', ext: 'aar')
+    compileOnly(name: 'com.heytap.msp', ext: 'aar')

把编译方式从implementation变成compileOnly

在工程的build.gradle文件中加入如下代码：

allprojects {
    repositories {
        
        flatDir { dirs '../frameworks/baseAarInfoLib/libs', '../baseAarInfoLib/libs', '../modules/module_push/libs' }
    }
}

其实就是把library中的libs文件夹作为aar包的加载源。

在application module的build.gradle文件中加入如下代码：

    api(name: 'vivo_pushSDK_v3.0.0.4_484', ext: 'aar')
    api(name: 'com.heytap.msp', ext: 'aar')

room升级到2.5.0

升级koltin原因就是升级了room，导致了gradle也升级

通过Android studio build 结果编译的时候一直报错，也看不出什么错
A failure occurred while executing org.jetbrains.kotlin.gradle.internal.KaptExecution
A failure occurred while executing org.jetbrains.kotlin.gradle.internal.KaptExecution

得通过下面的命令编译，能看到错误信息

./gradlew assembleDebug --stacktrace

通过如下命令能知道依赖关系

这个不好搞，我把permissionsdispatcher升级到最新版本还是报这个错。我研究了一下com.squareup:kotlinpoet:1.12.0 是androidx.room:room-compiler:2.5.0引用的，这样会把permissionsdispatcher引用的kotlinpoet版本也会从1.3.0变成1.12.0

，然后就报上面的错了。即便，我强制让kotlinpoet是1.3.0版本，room2.5.0又报错了，它得用kotlinpoet1.12.0版本。这两个库使用kotlinpoet的版本有冲突

permissionsdispatcher升级折腾了几小时，包名进行了改变

妈蛋，解决不了了

可能是room版本太新，降低到2.4.3

把room版本降低到2.4.3，library aar包的问题和permissionsdispatcher的问题都没有了。

最终的配置是：
gradle是6.3，gradle插件是4.0.1，kotlin 1.6.10，room 2.4.3

太难了，折腾了我三四天
