gradlew setupDecompWorkspace --refresh-dependencies fail

[JMAS]

I'm learning Java specifically for Minecraft mods for my son.  His preferred version is 1.7.10, because of other mods made for that version that do not exist in other versions of Minecraft.

The forge version is the 1558 build for 1.7.10.  Java version is 1.8.0_231.  Was working with 111 but had repeated issues.
I have installed, uninstalled and re-installed Java repeatedly, making sure that I have a fresh slate for each failed attempt with Forge in Eclipse.
I am attempting to follow the instructions at: https://techwiseacademy.com/minecraft-modding-setting-up-your-environment/ for modding.
I followed the instructions to the letter, and additionally am taking the Mr. Crayfish course at:

 

but when I attempt to "run" the code at 4:03 in the video, I receive the error: "Errors exist in required project(s):  

                                                                                                                                                               forge-1.7.10-10.13.4.1558-1.7.10-src

                                                                                                                                                                Proceed with launch?"

 

which I suspect stems from an incomplete install of the command: gradlew setupDecompWorkspace --refresh-dependencies
(from the first URL).

 

Here is the output from the command window:

You can see a number of things skipped from ":downloadMcpTools" forward.

I have spent the last week troubleshooting, trying to get Eclipse to cooperate, changing the Path and JAVA-HOME, adding and removing Java, updating Java, manually trying to import data files into Eclipse, re-running gradlew repeatedly with different parameters.  I have succeeded in getting Eclipse to change from 200 red X's in the package manager down to just one, but of course it is the critical one that snags my entire operation.  "Minecraft" has never showed up in the package manager.

Half my hair has been pulled out and I have to admit the need for help.
If Eclipse worked with Forge, that would be really great.  I really need your help because I can't get it to do so on my own.

I submitted this as a bug with Eclipse only to have them bounce me to you.

Thanks in advance for helping solve this,
Marc

Dear Marc,

this is the bug tracker of Eclipse. I can't see a bug with Eclipse itself here. It is more a usage problem with the Minecraft project. Please address your issue in their forum:
https://www.minecraftforge.net/forum/

The Gradle command concluded successfully, but there will be reasons why there are still problems in your workspace. I don't see anything here, and please don't expect that we try to follow the mentioned video for reproduction.

You may attach screenshots and maybe the error log here, or ask in the Eclipse foum
https://www.eclipse.org/forums/index.php/i/

Kind regards,
~Karsten

Additionally, I installed this off of the "C:" drive because Microsoft permissions issues were adding a ton of errors, which were resolved by installing as Administrator on the H: drive.

1.7.10 is no longer supported on this forum due to its age.

Please update to a modern version of Minecraft to receive support.
