.Jar not opening

[savgesnake32]

java version "1.8.0_281"


Java(TM) SE Runtime Environment (build 1.8.0_281-b09)


Java HotSpot(TM) 64-Bit Server VM (build 25.281-b09, mixed mode)


(my name)@(my name)-MacBook-Air ~ % java -jar/Users/(my name)/Desktop/MinecraftServer/server.jar


Unrecognized option: -jar/Users/(my name)/Desktop/MinecraftServer/server.jar


Error: Could not create the Java Virtual Machine.


Error: A fatal exception has occurred. Program will exit.

I was trying to create a Minecraft server and when I went to open the .jar it wouldn't open. I would get the animation of the coffee mug icon doing the thing as it gets opened but no window shows up. my Java is up to date I believe.

You need to add a space between -jar and /Users.

 

[casperes1996]

You need a space there, mate. After -jar

 

[savgesnake32]

thank you both, I will try it.

I can't access Eula.txt because it is in the .jar, and I can't open the .jar which is the problem.

In my experience JARs work best when launched from the directory in which they are located.
Thus, you may need to cd into the directory first and then launch the JAR file from therein.

Jars are kinda just zip files. Try renaming it .zip instead of .jar; That way you should be able to read the text files for instructions. When done, return it to a .jar.

Correct; Unless configured otherwise, the Java command will use the CWD as the relative path for all paths referenced, including from within a jar. - Though most people who package jars will configure them to use paths from the jar itself rather than CWD; Worth a shot if there are path errors though

when I renamed it .zip it opened into Archive Utility it made a folder called "Server" and a million jar files were in it.

How to you do that? sorry my experience with Mac's or

how do you do that? my experience with Mac's or much relating to things like this is limited to installing mods, shaders, etc. and this kind of thing never happened.

"cd" is short for Change Directory. It's a common Unix command. You just go
cd [directory you're changing into]
So in your case
/Users/(my name)/Desktop/MinecraftServer

Obviously fill in the name

but it already says that. it looks like I just need to agree to the Eula, which I assume means changing the false to true.
and also I can't edit things above it after I drag the .jar into the terminal

Based on what you've written above, no, it doesn't already say that. It says ~; Which means your home directory
What you may be confusing it with, is the input you give to the java command itself which is separate from what we're talking about here. The directory your Terminal shell is in vs. the directory java should load the jar from

so I should change the "~ ;" into a "vs"?

I can't edit the ~ ;. I can't delete it after highlighting, or anything. please simplify.

No; vs. is short for versus; That was part of a sentence.
Before you run the java command, you should run the cd command with the directory path as an arguument

You're still not quite following the instructions

I said to run the cd command with the path as the argument; I.e.
cd /Users/(name)/Desktop/MinecraftServer

and then the java command; Again, remember space after -jar

ohhh, so I need to add the "cd "(with the space) before the rest?

To be quite honest I didn't really actually follow along with what we were trying to make work, but I am happy it worked it, hehe

If you ever want I'll teach you the idea behind how all this Terminal kung-foo works, but until then enjoy your Minecrafting stuff

I would LOVE to, but I'm afraid school is keeping me very busy. if you offer your email we can stay connected for when I have time to learn!
