jmeter5.4.1源码编译（IDEA）问题解决

问题现象：最近想更深入的研究下jmeter5.4.1的源码及功能具体实现，从官网download了个源码，在本地使用IDEA工具导入项目、编译时，报以下错误：

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 Gradle build processes (requires restart)
Your project may be using a third-party plugin which is not compatible wit
