I know that it says what's wrong, but my question is how exactly should I go about fixing it so that I don't mess something up in the process. Also, Jacky was wanting me to send the error output if there was one, which there was.

Sorry for taking so long to respond to this, as I have been quite busy. Currently I have a folder called "forge" for 1.8 and a folder called "forge1.12" for 1.12 on my desktop. Is there anything you can think of that could be conflicting between those two when I am trying to set up the 1.12 version, and can you have 2 workspace folders available to edit, though not open at the same time, and still have it work? Aside from that, Jacky, I tried doing what you said about finding and deleting the .gradle folder. I then installed the recommended version of forge for 1.12, and installed it. I then typed the command gradlew.bat setupDecompWorkspace in the folder "forge1.12" and the error it gave is below. Also, I am using windows. I then also typed "gradlew.bat eclipse" and this is the error that that gave.

Well, I tried to set up a modding environment for 1.12 in an attempt to fix this issue, but when I type "gradlew setupDecompWorkspace eclipse" (which has worked in the past), or just "gradlew setupDecompWorkspace" it says that recompileMc failed and gave a way to possibly fix it, which I attempted to fix with no results. I don't know if it is because I don't know enough about how things work with Minecraft modding yet, but things seem like they are being difficult for no reason. Anyways, if anyone has any idea for me to try to fix the issue I am having with 1.8 especially, or 1.12, then please let me know. Also, thank you for your help so far.

I guess my main question at this point is where does the error lie and how could it be fixed? I'm unsure if the error is being caused by trying to load the new textures on to the new items/blocks, since they worked before, although having the black and purple default texture, or if the error is due to something in my modding setup not being compatible with something else in the setup for 1.8. I mean, if this is possible to fix while still using 1.8, I would prefer to do that for now, at least until I'm done with the book. After that though, I might start looking into how things are done in some of the newer versions.

It gave the same error, and is this a case where I have no choice but to update to a newer version? If so, what version would involve the least amount of changes to the code, as I am still semi new to this?

I apologize, I am not regularly post forum posts, so I did not think to put the console in a spoiler tag. My recent edit should fix that.

I went to the site that you suggested, it proofread some of the code, then I copied over the changes, but I still seem to be having the same issue. Thank you for telling me about the json syntax checker though, I'll definitely have to save that one to use for any later json files I make.

I'm using 1.8 because that is what the book specified based upon when it was published. Are the more recent updates compatible with the modded code that works for for 1.8?

I don't know if this is an error many other people are having, but I have been trying to learn how to code Minecraft mods using Java Eclipse from a book I purchased, and I recently finished the section that involves making new blocks, items, and textures for said blocks and items. I've followed what the book said, and tried to run the client only to have it crash with the error ("AL lib: (EE) alc_cleanup: 1 device not closed Java HotSpot(TM) 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release") at the 7/7 stage on the loading screen. I have also had to reinstall the whole modding setup that allowed everything to work before, including the relevant Java versions that allowed Java Eclipse to work because of an error that would not let Eclipse open, caused by some of the older java versions being deleted. After I got everything working with Eclipse again, I copied the "src" file in the forge folder were the mods being worked on were stored to the new forge directory and everything seemed to be working well, until I tried to run the client. I was also using Java Eclipse Neon before and I am now using Java Eclipse Oxygen now (provided that helps at all). I am mainly asking here, because I have tried to troubleshoot the issue myself by looking up the error, but with no success. I would be very happy if anyone knows what the issue is and how to fix it. I'm sorry if I did a bad job of explaining anything. Here is the console output in Eclipse.
