Android studio Android Studio 3.1构建失败，ClassNotFoundException

在Android Studio（AS）更新到3.1版后构建项目时，我遇到此错误：

org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':MyModule:transformClassesWithProfilers-transformForDebug'.
    at org.gradle.api.internal.tasks.execution.ExecuteActionsTaskExecuter.executeActions(ExecuteActionsTaskExecuter.java:100)
...
...
Caused by: java.lang.RuntimeException: java.lang.ClassNotFoundException: package.mymodule.MyClass

但实际上，package.mymodule.MyClass类是可用的。 在升级到AS v3.1之前，它也是作为v3.0.1构建的

只有在Android Studio中构建时才会发生这种情况。使用从控制台生成项目时

>gradlew assembleDebug

它构建时没有错误。 我还尝试在gradle-wrapper.properties中使用以前的gradle版本4.1（而不是4.4）：

distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip

前者是build.gradle中的gradle插件版本3.0.1（而不是3.1.0）

dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
}

没有成功。在构建v3.1时，我仍然会遇到相同的错误。 我还尝试禁用Instant Run。这没用

以下是完整的堆栈跟踪：

你知道如何解决这个问题吗？

我已经通过从Git签出另一个项目副本解决了上述问题。之后，我的项目也在用AS 3.1构建

我还没有弄清楚确切的原因。这就是我所做的：

1） 再次从Git中删除项目文件夹和克隆的存储库，使用与以前相同的文件夹名称>我再次遇到与上面相同的错误

2） 使用另一个文件夹名>works…，再次从Git中删除项目文件夹和克隆的存储库

无论如何，现在我对AS 3.1也有同样的问题。禁用即时运行后，构建工作正常
