Before this question gets closed for already being asked, as far as I can see it is a vague and common error so this is different from other questions.
I fixed the error in my previous post by installing a slightly different version of Forge, but have now reached Step 5 of this tutorial. When I use .\gradlew build with the example mod, everything seems to work fine (although I cannot find the console output) But when I edit the mod to how the author describes, I get many errors.
The example mod:
package com.example.examplemod;
import net.minecraft.init.Blocks;
import cpw.mods.fml.common.Mod;
import cpw.mods.fml.common.Mod.EventHandler;
import cpw.mods.fml.common.event.FMLInitializationEvent;
#Mod(modid = ExampleMod.MODID, version = ExampleMod.VERSION)
public class ExampleMod
{
public static final String MODID = "examplemod";
public static final String VERSION = "1.0";
#EventHandler
public void init(FMLInitializationEvent event)
{
// some example code
System.out.println("DIRT BLOCK >> "+Blocks.dirt.getUnlocalizedName());
}
}
How I changed it, following the tutorial:
package com.example.examplemod;
import net.minecraft.init.Blocks;
import cpw.mods.fml.common.Mod;
import cpw.mods.fml.common.Mod.EventHandler;
import cpw.mods.fml.common.event.FMLInitializationEvent;
#Mod(modid = ExampleMod.MODID, version = ExampleMod.VERSION)
public class ExampleMod
{
public static final String MODID = "examplemod";
public static final String VERSION = "1.1";
#EventHandler
public void init(FMLInitializationEvent event)
{
Block amethystOre = new ModBlock(Material.rock, "amethystOre");
GameRegistry.registerBlock(amethystOre, "amethystOre");
}
private class ModBlock extends Block
{
public ModBlock(Material material, String blockName)
{
super(material);
this.setBlockName(blockName);
this.setBlockTextureName(MODID + ":" + blockName);
this.setCreativeTab(CreativeTabs.tabBlock);
}
}
}
When I run .\gradlew build, I get:

I don't know a whole lot about Java (I just started learning it) but I would assume that copying the tutorial character-for-character should result in an error-free program. Apparently not.
Looking at the error output on the compiler, the first error is 'The import net cannot be resolved' (line 3) I don't know why though.
Any help is much appreciated,
Ben
(From comment)
Import are wrong. You should use net.minecraft.* not net.minecraft.init.* :
import net.minecraft.block.Block;
import net.minecraft.block.material.Material;

So I have am trying to edit a class file that is in a .jar file (the .jar file has a few other classes but I am only trying to edit this one). I used the source .java for this specific class and I am having trouble compiling it into a class, because the compiler calls errors because it is calling things from the package.
Does anybody know what the problem is?
Alternatively, it would be really helpful if someone knew of a program that would allow me to directly edit the code of a .class file in a .jar file without all the decompiling and recompiling.
Extra information
The .jar file is a Minecraft mod I'm whipping up for a friend.
Code of original .class (which works):
package pw.cinque.cpsmod;
import cpw.mods.fml.common.eventhandler.SubscribeEvent;
import cpw.mods.fml.common.gameevent.TickEvent;
import cpw.mods.fml.common.gameevent.TickEvent$ClientTickEvent;
import net.minecraftforge.client.event.MouseEvent;
import cpw.mods.fml.common.eventhandler.SubscribeEvent;
import cpw.mods.fml.common.gameevent.TickEvent;
import net.minecraftforge.client.event.MouseEvent;
import pw.cinque.cpsmod.CPSMod;
public class ClickListener
{
public ClickListener() {}
private boolean hasClickedThisTick = false;
#cpw.mods.fml.common.eventhandler.SubscribeEvent
public void onMouse(MouseEvent event) {
if (button != 0) {
return;
}
if ((CPSMod.preventDoubleclicks) && (buttonstate) && (hasClickedThisTick)) {
event.setCanceled(true);
return;
}
if (buttonstate) {
hasClickedThisTick = true;
CPSMod.addClick();
}
}
#cpw.mods.fml.common.eventhandler.SubscribeEvent
public void onClientTick(cpw.mods.fml.common.gameevent.TickEvent.ClientTickEvent event) {
hasClickedThisTick = false;
}
}
Code of file I edited:
package pw.cinque.cpsmod;
import cpw.mods.fml.common.eventhandler.SubscribeEvent;
import cpw.mods.fml.common.gameevent.TickEvent;
import cpw.mods.fml.common.gameevent.TickEvent$ClientTickEvent;
import net.minecraftforge.client.event.MouseEvent;
import cpw.mods.fml.common.eventhandler.SubscribeEvent;
import cpw.mods.fml.common.gameevent.TickEvent;
import net.minecraftforge.client.event.MouseEvent;
import pw.cinque.cpsmod.CPSMod;
public class ClickListener {
private boolean hasClickedThisTick = false;
int newVar = 0;
#SubscribeEvent
public void onMouse(MouseEvent event) {
if (event.button != 0) {
return;
}
if (CPSMod.preventDoubleclicks && event.buttonstate && this.hasClickedThisTick) {
event.setCanceled(true);
return;
}
if (event.buttonstate)
{
this.hasClickedThisTick = true;
CPSMod.addClick();
newVar = CPSMod.getClicks();
if(newVar > 5)
{
CPSMod.addClick();
}
}
}
#SubscribeEvent
public void onClientTick(TickEvent.ClientTickEvent event) {
this.hasClickedThisTick = false;
}
}
These are the error messages I get when I try to compile it.

You need to compile that class with all its dependencies, otherwise it will not work. Probably you should get all the files from that .jar, make the modifications you want and then compile and compress it again.
The following code:
import org.biojava.bio.structure.ResidueNumber;
import org.biojava.bio.structure.Structure;
import org.biojava.bio.structure.io.PDBFileReader;
import org.biojava3.protmod.structure.ProteinModificationIdentifier;
public class Test3 {
public static void main(String[] args) {
try {
PDBFileReader reader = new PDBFileReader();
reader.setAutoFetch(true);
// identify all modifications from PDB:1CAD and print them
String pdbId = "1CAD";
Structure struc = reader.getStructureById(pdbId);
Set<ModifiedCompound> mcs = identifyAllModfications(struc);
for (ModifiedCompound mc : mcs) {
System.out.println(mc.toString());
}
// identify all phosphosites from PDB:3MVJ and print them
pdbId = "3MVJ";
struc = reader.getStructureById(pdbId);
List<ResidueNumber> psites = identifyPhosphosites(struc);
for (ResidueNumber psite : psites) {
System.out.println(psite.toString());
}
} catch(Exception e) {
e.printStackTrace();
}
}
}
...results in the following stream of error messages:

I have manually downloaded every jar file for Biojava 4.2.4 and stored each of them in a desktop folder (included in my classpath), listed each individually on my classpath, and stored both in C:\program files\java\jdk1.8.0_112\jre\lib\ext
and C:\program files\java\jdk1.8.0_112\jre\ext yet the errors are not resolved.
I'm using a Windows 10 machine, Java JDK8_112, and BioJava 4.2.4
Any help would be appreciated.
Thank you.

As far as we can deduce from what you've shown, there's a couple of things that go wrong:
There seems to be an issue with your invocation of javac, it is missing a classpath that refers to the Apache Thrift library. You can specify the classpath using the -cp parameter. Make sure it points to the current directory, the Thrift libraries and any other libraries you might be using.
Your class JavaServer should be declared in a file named JavaServer.java (exactly as the compiler error says). Apparently, it's called javaserver.java, which is not the same (at least not on non-Windows platforms).
Sample .thrift files attached to official web tutorial have some errors (July 2015, v0.9.x).
Inconsequences in sample struct/classes etc, sample doesn't compile in few languages.
Version of this files in official tar.gz are good.

javac -d bin -sourcepath src -cp :lib src/SmackCcsClient.java
I have tried various variations but i keep getting the same output every time.
UPDATE 2:
running the command:
javac -d bin -sourcepath src -cp lib/*.jar src/SmackCcsClient.java
gave the following output:
javac: invalid flag: lib/smack-android-4.1.1-javadoc.jar
Usage: javac <options> <source files>
use -help for a list of possible options
I am following different tutorials but i cannot figure out how to do this correctly.
A correct command would be (assuming all needed .jar files are actually in the lib/ folder, and all sources are in the src/ folder):
javac -d bin -sourcepath src -cp $(find lib -iname *.jar | xargs | tr " " ":") src/SmackCcsClient.java
The tricky part (within $( )) is building something like a.jar:b.jar:c.jar (no spaces, separated by :) from all the jar-files in the lib/ folder. Your attempt using -cp lib/*.jar failed because there were spaces instead of : separating the jar-files, and javac thought that the second jar-file it found was actually java source that you wanted to compile. And then complained that it did not know how to compile jar-files.
A simpler version (that relies on there being no sub-directories in lib/) is
javac -d bin -sourcepath src -cp $(echo lib/*.jar | tr " " ":") src/SmackCcsClient.java
I have the following file called Test.Java the code of which is
package example25;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.util.Iterator;
import org.jibx.runtime.BindingDirectory;
import org.jibx.runtime.IBindingFactory;
import org.jibx.runtime.IMarshallingContext;
import org.jibx.runtime.IUnmarshallingContext;
import org.jibx.runtime.JiBXException;
public class Test
{
public static void main(String[] args)
{
try
{
// unmarshal customer information from file
IBindingFactory bfact = BindingDirectory.getFactory(Order.class);
IUnmarshallingContext uctx = bfact.createUnmarshallingContext();
FileInputStream in = new FileInputStream("D:\\Java Libraries\\jibx\\dwcode2\\starter.xml");
Order order = (Order)uctx.unmarshalDocument(in, null);
// compute the total amount of the order
float total = 0.0f;
for (Iterator<Item> iter = order.getItemList().iterator(); iter.hasNext();)
{
Item item = iter.next();
total += item.getPrice() * item.getQuantity();
}
order.setTotal(new Float(total));
// marshal object back out to file (with nice indentation, as UTF-8)
IMarshallingContext mctx = bfact.createMarshallingContext();
mctx.setIndent(2);
FileOutputStream out = new FileOutputStream("c:\\out.xml");
mctx.setOutput(out, null);
mctx.marshalDocument(order);
System.out.println("Processed order with " + order.getItemList().size() + " items and total value " + total);
}
catch (FileNotFoundException e)
{
e.printStackTrace();
System.exit(1);
} catch (JiBXException e)
{
e.printStackTrace();
System.exit(1);
}
}//end main
}//end class
Here is how i am trying to compile this file and the output that i get

All the class files used by Test are present next to it and have been properly compiled.
Test is the last file that is giving me trouble. Furthermore some of the classes used in test are present in C:\jibx\lib> as opposed to C:\jibx\tutorial> from where i am executing commands. Any suggestions on how i cld resolve this issue without modifying my previously generated class files would be appreciated.
add the directory C:\jibx\lib to your classpath e.g.
SET CLASSPATH=%CLASSPATH%;C:\jibx\lib;.
and then do a javac
As there are some import errors set the class path properly as Satya said, And the your current class in some directory you should compile it with -d attribute of javac
As shown below
javac -d . YourfileName.java
