[Ivo Sestren Junior]

Hi, i have activator-1.2.3, java-8 64bits in windows 8.

I get this error on run "activator new projectname"

Erro: Unrecognized VM option 'MetaspaceSize=64M'

How i resolve this?

I was having the same problem.

What I figured out is that I had my JAVA_HOME set to JDK 1.7, but when i typed java -version it returned Java 8.  

the solution in my case was to update my JAVA_HOME to point to the Java 8 directory.

Hope that helps.

David, thanks for that tip, had the same problem here.

C:\Dev\scala\activator-1.2.2>java -version

java version "1.8.0_05"

Java(TM) SE Runtime Environment (build 1.8.0_05-b13)

Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)

C:\Dev\scala\activator-1.2.2>echo %JAVA_HOME%

C:\Program Files\Java\jdk1.7.0_55\
