I am trying to compile a servlet on my tomcat classpath and it will not work even though I believe I have the right command. I want to use json utils for parsing and the obvious servlets api. However, I cannot get the package to be ever found. I reinstalled java, which is java 11, and I also reinstalled Tomcat, which is Tomcat 10. This is on a Windows machine.
This is what I do in the console and what gets outputted.

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:

Execution failed for task ':compileJava'.
> Compilation failed; see the compiler error output for details.
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;

You need Winium web driver jar for the mentioned imports
winium-webdriver-0.1.0-1-sources.jar This jar file is required. This only contains the package "org.openqa.selenium.winium" which is missing in your case.
Try adding it as maven dependency if this is a maven project or search for the below dependency in maven central and download as zip. extract and add to build path of your project=> Java build path -> libraries.
<dependency>
<groupId>com.github.2gis.winium</groupId>
<artifactId>winium-webdriver</artifactId>
<version>0.1.0-1</version>

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.
I am trying to compile a java file using SMACK for the XMPP libraries. In the folder of the java file i have included a Libs directory including all the *.jar files for SMACK but when i try
javac filename

how do i compile this correctly? is there some extra command needed for the smack library?
UPDATE:
i have created the following folder structure:
root
->bin
->src
->lib
I have tried compiling with different javac commands like:
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
