fair warning, I'm almost completely new to modding, having only gotten far enough to implement a few items and some untextured blocks. Even that much I only accomplished thanks to CJMinecraft's tutorials (available here), so if I say or do something 'stupid', please have patience.
I tried to install/setup a workspace on a new computer I just got not too long ago, but for some reason, the same steps in the tutorial I'm following (and which I used to set a workspace up on my old computer), well, they aren't working. here's what I did before I got an error (note: This list is only the steps I went through up until I initially got the error in step 5; as such, anything I did to try to resolve the error isn't included):
I installed 64-bit Java
I set the Java_home environment variable to point to it
I downloaded the MDK and extracted it to the folder I want to set up as my workspace
I opened up command prompt at the location by calling "start CMD" in powerShell there
I tried to run the command gradlew SetupDecompWorkspace eclipse, but got the error "The system cannot find the path specified. Error: could not find or load main class org.gradle.wrapper.GradleWrapperMain"
after getting that error, I tried a few things to try to resolve it, including (but not limited to) inspecting gradle-wrapper.jar to see if it was where it's supposed to be and had the method in question (spoiler alert, it did), trying again after deleting .gradle from my user directory, and repeating steps 3-5 in various locations (It worked okay on my desktop for some reason, despite the only difference between the folders' permissions being that one inherits from my user directory and one inherits directly from desktop). Try as I might, I can't figure out why it won't setup in the folder I want. Please help.
