I am running an Ant Build in Eclipse Oxygen and am getting this error:
[xslt] Warning: The encoding 'UTF-8' is not supported by the Java runtime.
[xslt] Warning: encoding "UTF-8" not supported, using UTF-8
BUILD FAILED
I have tried multiple JREs. Currently I am on jre1.8.0_91.
Is this really a Java error? Is this a configuration error?
