Can't get Java File(s) to execute

[Zeredos]

Hello, i built my first PC about 2 weeks ago now, all has been smooth sailing so far until i have noticed that when trying to install Minecraft Forge i cannot get the file to work properly. When i try to execute it i just get a quick load wheel on my cursor then nothing. I have done several troubleshooting steps of my own from doing some research such as:

1. Setting the correct path to the folder in Environment Variables in This PC
2. Reinstalled both JRE and JDK (separately)
3. Making a separate .bat file with the Java file to see if it'd run and all i got was the cmd.exe doing this:

I moved on from a laptop and i naturally never had any issues regarding Java ever, so with finally building a PC and experiencing it this is definitely all new to me, i appreciate all your help and time.

Try adding "-verbose" to see if you get more enlightening information.

Does double clicking on the program like its a exe not work?

Sorry for the late reply, could you specify on where to put it? i tried at the end and after -jar and nothing happened other than showing "-verbose" in the cmd window, sorry for a most likely obvious question.

No it does not, as i said it just quickly shows a loading wheel on my cursor and then nothing afterwards.

I'm pretty sure for a bat file it would need to start with

@ECHO OFF

And have the jar execution command on the next line

I did that and all it does now is open the cmd window with nothing in it.

Try putting the whole command in quotation marks.  Oddly enough, that has worked for me with this exact issue in the past.

Gave it a whirl and all i got was it quickly showing an open window on the taskbar and quickly disappearing, nothing even shows up on the desktop. Just to 100% make sure, you're referring to doing it like this correct?

That's more or less what I was thinking, although I give the full path to 'java' as "C:\Program Files\.......\java -jar [etc etc]"

Yeah, ibieve on windows you do have to give the path. 

On Linux all you need is to be in the directory of the file and run

sudo java -jar [filename].jar

Which is all he is doing.

But on windows you might need to specify the Java location. 

Or drag the jarfile onto the Java.exe program

I typed in the full path and unfortunately the same thing is happening.

Nothing with dragging either, cmd.exe window pops up for a split second then poofs, brain is quite rattled at this point lol.

To make sure you have the JDK property installed and in your path, you can open powershell and run java -version and javac -version and see if the versions match. If not, uninstall everything with java in the name an reinstall your JDK from https://www.oracle.com/java/technologies/javase-jdk16-downloads.html. Test your java install with your forge installer again, or if that doesn't work use something known to work like Minecraft Server to test.

Everything appears to be the same version, not sure on the additional numbers up top though.

[piestormer]

Yeah that seems fine. Any luck with Minecraft Server? It's possible that your forge is just garbage (oh, and use powershell to test - I really don't trust CMD to work the way I'd expect it to)

Well i've made sure to test with multiple versions of Forge and i get the same results if that means anything, as for the server could you tell me how to do that?

[piestormer]

Oh, I was just suggesting Minecraft Server as good known working java code to run - but any other known good java program would equally work. If I remember correctly Minecraft will tell you what version of java the game Is running in if you press f3 in game - if the java version number in the top right is 16.0.1 then it's working and running

 

Edit: my memory is not correct Minecraft uses it's own imbedded java now. Good luck op, forge is always a pain in the ass

Ah ok, well i hopped on the game and found that the java ver. is 1.8.0_51 apparently. But i am still unsure on what that means, is that the root cause of this? i am pretty stumped at this point.

Maybe "java -verbose -jar <jarfile>"? -jar might expect the jar file as the immediate next argument.

No luck, just opens cmd.exe blank.

No output at all in the powershell/cmd window where you ran that command? Hmm. No idea then. It's been a long time since I dealth with Minecraft jar-shenenigans.

If i remove "@ECHO OFF" it will loop like it did originally except show "-verbose" in the command line, but no additional information is given. Otherwise yep, just opens it essentially as if waiting for you to type.

Gonna bump this

Have you tried one of these methods (specifically method 5 and 6)?
