Unable to Launch

[Sergix]

Hi, I'm new to modding development and was trying to launch Forge 1.7.10-10.13.0.1152 in Eclipse Java EE IDE. I setup the eclipse folder with "gradlew setupDecompWorkspace" and "gradlew eclipse", and am running JDK 7_u80 and jre7, for it to work with 1.7.10. However, when I attempt to launch the ExampleMod included with the installation, I get the following error log:

I am at a complete loss as of what to do. I have tried running jre1.8.0_u121 instead of the default jre7 runtime, but I get the following error:

I have also set up my PATH variable to be set to "C:\Program Files\Java\jdk1.7.0_80\bin", and also the JAVA_HOME variable to the same location.

 

I do know that nowadays Forge does not technically support 1.7.10 anymore, but I would like some help, as I have a book on Mod Development for 1.7.10 (Sams Teach Yourself Minecraft Mod Development by Jimmy Koene) and would like to not have to purchase a new one.

 

I have also attached an image of my IDE and the JRE settings window in case you need it.
