CodenameOne simulation not finding Theme.res

Question

I'm new to codename one and attempting a brand new installation and have not been able to run the simulator.

I've installed eclipse Version: Oxygen.2 Release (4.7.2) Build id: 20171218-0600 with Java 1.8.0_162 on windows 7 enterprise service pack 1 and am experiencing the following exception which seems related to

[EDT] 0:0:0,64 - Exception: java.io.IOException - /theme.res not found

I've followed these threads and applied all suggestions with no success. Can I provide more information?

One strange thing I noticed is on the New CodenameOne Project window has a grayed out Java 8 Project checkbox and a message underneath "Java 8 project requires a newer Eclipse version.

It seems that Codename One isn't detecting the JDK 8 you are using. Are you sure this is the JDK picked by Eclipse? Make sure the JDK is specified in the eclipse.ini file and recreate the project: wiki.eclipse.org/Eclipse.ini — Shai Almog
Adding -vm C:\Program Files\Java\jdk1.8.0_162\bin\javaw.exe so I made it the answer. — Dave

Add -vm to my eclipse.ini did the trick:

-startup
plugins/org.eclipse.equinox.launcher_1.4.0.v20161219-1356.jar
--launcher.library
C:\Users\daveb\.p2\pool\plugins\org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.551.v20171108-1834
-product
org.eclipse.epp.package.jee.product
-showsplash
org.eclipse.epp.package.common
--launcher.defaultAction
openFile

-vm

C:\Program Files\Java\jdk1.8.0_162\bin\javaw.exe**

--launcher.appendVmargs
-vmargs
