记一次Flutter升级到3.19，Android遇到的问题

某些插件build报错

1. java.lang.IllegalAccessError: class org.gradle.internal.compiler.java.ClassNameCollector (in unnamed module @0x1be64679) cannot access class com.sun.tools.javac.code.Symbol$TypeSymbol (in module jdk.compiler) because module jdk.compiler does not export com.sun.tools.javac.code to unnamed module @0x1be64679

   解决办法：在gradlew.propertis中添加如下配置

   org.gradle.jvmargs=--add-exports=jdk.compiler/com.sun.tools.javac.code=ALL-UNNAMED
   

2. • What went wrong: Execution failed for task ':connectivity:compileReleaseJavaWithJavac'. Compilation failed; see the compiler error output for details.

   解决办法：修改connectivity插件的build.gradle内容如下

   group 'io.flutter.plugins.connectivity'
   version '1.0-SNAPSHOT'
   
   buildscript {
       repositories {
           google()
           mavenCentral()
       }
   
       dependencies {
           classpath 'com.android.tools.build:gradle:4.1.0'
       }
   }
   
   rootProject.allprojects {
       repositories {
           google()
           mavenCentral()
       }
   }
   
   apply plugin: 'com.android.library'
   
   android {
       compileSdkVersion 30
   
       compileOptions {
           sourceCompatibility JavaVersion.VERSION_1_8
           targetCompatibility JavaVersion.VERSION_1_8
       }
       defaultConfig {
           minSdkVersion 16
       }
   }
