Hi, I’m getting this error when building my project. I’m on Gradle 4.1
Caused by: java.lang.NullPointerException: null value in entry: rootSpec$1=null
Cannot determine task state changes for task ':3a825075ed15f141:master_project:sub_project:processResources'
Could anyone please point me to the right direction as what it may be caused by? What is this random string in front of my master_project?

Removing .gradle directory helps but is not a viable solution as the problem keeps coming back.
