CAPSULE EXCEPTION while deployNodes task

问题:

I am trying to deploy IRS demo application on windows server, I have installed java already:

C:\Users\Administrator>java -version java version "1.8.0_181" Java(TM) SE Runtime Environment (build 1.8.0_181-b13) Java HotSpot(TM) Client VM (build 25.181-b13, mixed mode)

I am getting following exception for node:

CAPSULE EXCEPTION: Could not find Java installation for requested version [Min. Java version: 1.8.0 JavaVersion: null Min. update version: {1.8=171}] (JDK required: false). You can override the used Java version with the -Dcapsule.java.home flag. (for stack trace, run with -Dcapsule.log=verbose)

can you help with whats going wrong? In the same machine environment, I have previously developed and deployed many corDapps.

This was caused by forgetting to update the Windows environment variable after installing Java 1.8.181.

Forgetting to update the Windows environment variable has also been known to cause errors of the type:

CAPSULE EXCEPTION: Illegal char <"> at index 0: "C:\WINDOWS while processing system property java.library.path: C:\Program Files\Java\jdk1.8.0_191\bin;
