今天是上坟(班）第一天,刚拿到一个项目，正好看到这个gradle优化文章【Gradle-14】编译优化之Gradle最佳配置实践[https://juejin.cn/post/7344625554529730600]。哎，我就喜欢这种不用写代码的技术，

org.gradle.unsafe.configuration-cache=true //配置缓存

这个不错，立马加上。加好了项目也编译好了，一跑就完犊子。错误如下：

Configuration cache state could not be cached: field 'configFile' from type 'com.huawei.agconnect.agcp.AGCPluginTask': error writing value of type 'com.huawei.agconnect.agcp.ConfigFile'

                     > java.util.ConcurrentModificationException (no error message)

一眼盯真，这肯定是华为的错，然后开启华为论坛之旅，无果。查找良久，后来鼠标滑到了上边

- Task `:app:processDebugAGCPlugin` of type `com.huawei.agconnect.agcp.AGCPluginTask`: cannot serialize object of type 'com.android.build.gradle.internal.tasks.DexMergingTask', a subtype of 'org.gradle.api.Task', as these are not supported with the configuration cache.

翻译如下：
com.huawei.agconnect.agcp.AGCPluginTask”类型的任务“:app:processDebugAGCPlugin”：无法序列化“com.android.build.gradle.internal.tasks.DexMergingTask”类型的对象（“org.gradle”的子类型） .api.Task'，因为配置缓存不支持这些。
忽然就想到上面加的配置缓存。删掉，app run success ~~~
好了，问题解决，又是划水的一天。
