[1.5.1] noob tutorial issues

[Taledus]

I have started on the tutorials yesterday.  I got everything setup following the tutorials in the wiki.  Now I am on http://www.minecraftforge.net/wiki/Basic_Blocks trying to create my first block.  I seem to be running into errors by the end of the tutorial, and have even resorted to copy/pasting the code at the bottom to ensure that everything was correct, but still run into the same errors in Generic, GenericBlock, and GenericOre classes:

I am also getting this error since I opened back up Eclipse this morning:

 

 

Description	Resource	Path	Location	Type
Build path specifies execution environment JavaSE-1.6. There are no JREs installed in the workspace that are strictly compatible with this environment. 	Minecraft		Build path	JRE System Library Problem

 

 

 

In the "Materials" section I am unable to locate net.minecraft.src.Material also.  I am not sure if it is because I am new, or if this tutorial was written for a different version of MC, but could really use some advice here.

 

I just downloaded the most recent releases of both Eclipse and Forge yesterday to start modding, btw.

Seems to me your problem lies mainly in the fact that you haven't installed any JDK (Java Development Kit) this is essential since without it you can't develop Java applications. You'll have to install it, you can get the latest version here:

 

http://www.oracle.com/technetwork/java/javase/downloads/index.html

 

You should look after a download called "Java Platform (JDK) 7u17". Also the path to Material is net.minecraft.block.material.Material if I recall correctly

This was installed yesterday, but I forgot that I moved the forge directory this morning to a more permanent place on my hard drive.  I am just going to follow the steps again and start over.

 

Thanks

Okay, I reinstalled everything, and I am still getting the error about JavaSE-1.6.  However, per the tutorial:

 

You should also be able to use Java 7 (JDK 1.7), but doing so means that all users of your mod must also be using Java 7.

 

So, I am using the most recent 1.7.  After everything is installed I can launch Minecraft from Eclipse, and everything runs, so I don't guess that the warnings are of much concern.
