having trouble running gradle

Question

I typed in the command gradle -q run into the command prompt and I got the response

"Execution failed for task ':compileJava'.

Could not find tools.jar. Please check that C:\Program Files\Java\jre1.8.0_161 contains a valid JDK installation."

I don't understand what this means.

You'll need the JDK (as opposed to the JRE). More info here - https://stackoverflow.com/questions/1906445/what-is-the-difference-between-jdk-and-jre — Michael Easter, Jun 11 '18 at 12:14
I installed jdk. But the prompt is telling me that I need tools.jar — Max, Jun 11 '18 at 13:00

The error is basically saying that it can't find the JDK.

To fix the problem, you need to update/create your "JAVA_HOME" system variable to point to a valid JDK. Your problem may be that you haven't created that system variable.

Here are some instructions for how to do this in Windows.
