报错一：java.lang.NullPointerException: Cannot invoke "String.length()" because "" is null
解决方案：
I solved this problem by upgrading Android Gradle Plugin to version 8.3.1.
You can use Tools->AGP Upgrade Assistant to upgrade Android Gradle plugin.
报错二：Namespace not specified. Specify a namespace in the module's build file.
解决方案：
allprojects {
repositories {
google()
mavenCentral()
}
// This code is where all the magic happens and fixes the error.
subprojects {
afterEvaluate { project ->
if (project.hasProperty('android')) {
project.android {
if (namespace == null) {
namespace project.group
}
}
}
}
}
// This code is where all the magic happens and fixes the error.
}
报错三：Class 'kotlin.Suppress' was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.9.0, expected version is 1.7.1.
解决方案：
The expected version is the Kotlin for kotlin-gradle-plugin
The binary version is what is downloaded (or previously compiled) for com.android.tools.build:gradle
buildscript {
ext.kotlin_version = '1.5.20' // <= expected version is 1.5.1
}
dependencies {
classpath 'com.android.tools.build:gradle:7.3.1' // downloads 1.7.1 Metadata
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" // <= 1.5.20 used here
}
KGP、Gradle、AGP版本对应表：https://kotlinlang.org/docs/gradle-configure-project.html#apply-the-plugin
通过差对应表，将主工程下的KGP版本升级即可。
From
ext.kotlin_version = '1.7.10'
to
ext.kotlin_version = '2.0.0'
