[SOLVED] Why Can't I Compile and Run?

[JaredBGreat]

In tutorial videos people just download all the files, run the install.sh / install.bat, jump into Eclipse, and run the game right from there.  Yet, I get one set of errors after another, and I haven't even added any code of my own yet.  Why is this happening.  This is what I get:

 

A 51 second screen video is here:

 

All the code seems to be there, and there are no errors highlighted now.  What's going wrong?  Am I supposed to be able to test run this way?

You do have an error, shown in eclipse as a red X. Where is that error?

[JaredBGreat]

Thanks.  It says...

...but I'm not sure what it means.  I'm just trying to get set up and start learning.

[BrainStone]

There seems to be an issue with the set up. Try deleting everything (include the files that were in the zip) unzip all the files again and run the install script again.

 

I guess the installer was not able to download one libary. This happens every once in a while. (A reinstall is the simplest way to fix it)

[JaredBGreat]

I forgot I had started a tutorial, so I deleted it.  I got rid of the red X, but still get the same error, and there is an exclamation point that leads me to a class TaskWorldCreation.java in package net.minecraft.client.gui.  I still seem to get the same error message; the results haven't changed.

 

Other (!) are found, on in ThreadDownloadResources.java in net.minecraft.util; in RegionFile.java in net.minecraft.world.chunk.storage; also -- I know I didn't modify any of those.  All the tutorial stuff was in its own package.  Also, I was having trouble before I started the tutorial, but at first thought maybe some of the native libraries or something didn't like the deobfuscated version and that maybe it wasn't supposed to run.

OK, thanks, I've deleted and re-installed, but still no luck.

 

A couple things:

 

(1) I'm not sure what to pick to run (I've been using net.minecraft.client, and also tried start from the default package, both with similar results); I can start the net.minecraft.server, though and everything works fine.  Maybe I'm not starting from the right class?

 

(2) When downloading I see this message:

 

== MCP 7.51 (data: 7.51, client: 1.5.2, server: 1.5.2) ==
"scalac" is not found on the PATH.  Scala files will not be recompiled

 

...not sure if that might be what's missing.

 

Tried installing scala (sudo apt-get install scala), now I trying to install I get:

 

== MCP 7.51 (data: 7.51, client: 1.5.2, server: 1.5.2) ==
"scalac" does not support jvm-1.6 target, it is out of date. Ignoring

 

...and the same basic error as before when trying to test run.

 

Tried installing scala manually from download from scala-lang.org, no change.  I suspect this is the problem (not positive), but have no clue what to do about it.

 

EDIT: Tried switching to the new Minecraft 1.6.2 build, and things are even worse it seems.  I get the same scala error during installation.  When trying to compile / test run with that I get:

 

Exception in thread "main" joptsimple.MissingRequiredOptionException: Missing required option(s) ['version']
at joptsimple.OptionParser.ensureRequiredOptions(OptionParser.java:447)
at joptsimple.OptionParser.parse(OptionParser.java:437)
at net.minecraft.client.main.Main.main(Main.java:43)

 

I'm pretty sure its that scala not wanting to work with java less than 1.7 while the install seems to insist on 1.6.  Anyone know how to fix that (on linux), please?
