How to install Overture on Windows

Question

I'm running Widows 7 Professional on a 64-bit system with Java SE 10. I downloaded Overture-2.6.2-win32.win32x86-64.zip and unzipped it under c: and clicked on the Overture application. It started and asked for a workspace path. I took the default but it failed. The log file showed a bunch of Java errors include ClassNotFound. I moved the Overture folder to Program Files where the Java folder is. Failed again. The Overture manual indicates the download includes Eclipse. I removed the current Eclipse version in case that was the problem. Still failed. What am I doing wrong?

Answer 1

The Overture download web page has the text "(Java SE 8 is required)" I took that to mean 8 or later. They meant only 8 will work. I had Java 10 (current version) installed. When I removed Java 10 and installed Java 8 Overture loaded. I hope this answer saves others the time I wasted.

Answer 2

I tried to run the Overture 2.6.4 release candidate (which I will release on October 19, 2018) using Java 10 on Ubuntu, and I received the error shown below. It seems like this error is caused by the Eclipse version (Oxygen) that Overture builds against. By following the instructions found here https://wiki.eclipse.org/Configure_Eclipse_for_Java_9 I was able to fix the issue. Specifically by adding --add-modules=ALL-SYSTEM to the Overture.ini file. Does this solve your problem? Although the page was originally intended to cover Java 9 configuration it seems like the suggestions still work.

eclipse.buildId=unknown
java.version=10.0.2
java.vendor=Oracle Corporation
BootLoader constants: OS=linux, ARCH=x86_64, WS=gtk, NL=en_US
Command-line arguments:  -os linux -ws gtk -arch x86_64
