我刚刚更新了 android studio，无法构建我以前的项目。我遇到过这些错误：
class jdk.internal.loader.ClassLoaders$PlatformClassLoader cannot be cast to class java.net.URLClassLoader (jdk.internal.loader.ClassLoaders$PlatformClassLoader and java.net.URLClassLoader are in module java.base of loader 'bootstrap')
class jdk.internal.loader.ClassLoaders$PlatformClassLoader cannot be cast to class java.net.URLClassLoader (jdk.internal.loader.ClassLoaders$PlatformClassLoader and java.net.URLClassLoader are in module java.base of loader 'bootstrap')
Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)
Re-download dependencies and sync project (requires network)
The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem.
Stop …
