问题原因 #

该异常是由于Baseline Profile 1.3.3版本未适配AGP 8.7.x与Gradle 8.9的组合，插件在项目评估后期尝试修改已被锁定为final的experimentalProperties属性，触发了Gradle的属性不可修改校验。

解决方案 #

1. 升级Baseline Profile插件版本 #

将Baseline Profile插件升级到1.4.0及以上版本，该版本已修复此兼容性问题。修改项目根目录的settings.gradle或build.gradle中的插件声明：

id 'androidx.baselineprofile' version '1.4.0' apply false

2. 确认插件应用顺序 #

在模块的build.gradle中，确保Baseline Profile插件在Android插件之后应用，避免在错误阶段触发属性修改：

plugins {
    id 'com.android.application' // 或 com.android.library
    id 'androidx.baselineprofile'
}

3. 验证版本组合兼容性 #

如果升级插件后问题仍存在，可以尝试调整AGP或Gradle版本，保持三者版本的兼容性：

• 将AGP升级到8.8.x版本
• 或将Gradle版本调整为8.8版本
