Java can't compile in terminal because of external libraries

I'm on Ubuntu 22.04 trying to run my code in the terminal.
The program works without problems in VScode, also when running multiple instances.
The program is consisted of six class files.
The trouble occurs when I try and run it with terminal. When compiling the java file
with javac it shows errors at places where I use the external libraries.
If I compile it with VScode and run the class file in terminal, I get the following error java.lang.ClassNotFoundException
This is causing me problems since I'm also supposed to dockerize the program.

You can add the following code in your setting.json file "java.project.outputPath": "bin",
This will be the .class file generated by VS Code in the bin folder of the same directory when running the Java code.
You can use the java command after entering the file directory with the cd command.

This generally indicates that the class path with which you're compiling your program does not include the correct paths to your libraries. Assuming your libraries are jar files, your javac command should look something like this:
javac -cp libs/lib1.jar:libs/lib2.jar srcs/*.java
where libs/ is the relative path to your libraries and srcs/ is the relative path to your own java files.
And when you run the program, make sure your class path includes both the locations of your libraries and the location of your class files (which in this case would be the current directory):
java -cp .:libs/lib1.jar:libs/lib2.jar <MainClass>

Cannot run this program from cmd with classpath option

this is a beginner question. I am having a problem running my java program from command line. I am using Windows10.
The problem is the following. I have a folder named "folder1", which is located o the dekstop of my computer. So the full path would be
C:\Users\Ioanna\Desktop\folder1
Inside that folder I have created a second folder which I named folder2. so the path to this would be
C:\Users\Ioanna\Desktop\folder1\folder2
Inside folder2 I have a java file named example.java
I want to compile it and run this file with setting the -classpath option through cmd. I dont want to set the path or to add the folder to tha path from environment variables.
I am trying
C:\Users\Ioanna\javac -cp C:\Users\Ioanna\Desktop\folder1\folder2 example.java
but it says file not found.
I tried several other alternatives, but I can't seem to find how to compile successfully the program.

Code compilation (to bytecode) and code execution are two separate steps, in Java.
First, compile your .java to obtain the corresponding .class file (I'm assuming your folder paths are right):
C:\Users\Ioanna\javac C:\Users\Ioanna\Desktop\folder1\folder2\example.java
This will give you example.class in that same folder.
Next, run that class (provided it has a main() method):
C:\Users\Ioanna\java -cp C:\Users\Ioanna\Desktop\folder1\folder2 example

java expects the path of the file(s) to compile. And example.java is not in the current folder (C:\Users\Ioanna).
Use
javac Desktop\folder1\folder2\example.java

Program compiling in Eclipse but not in Command Prompt

Basically, my program compiles and runs fine in Eclipse but doesn't compile in Command Prompt. It gives me Symbol Not Found with the pointer on the name of one of my classes. I've never had this happen before- the only difference between this program and the other ones I wrote is that I made a package in Eclipse for them. Any ideas?

I think you didn't set the path correctly.
How to set Path in Java
The path is required to be set for using tools such as javac, java etc.
If you are saving the java source file inside the jdk/bin directory,
path is not required to be set because all the tools will be available
in the current directory.
But If you are having your java file outside the jdk/bin folder, it is
necessary to set path of JDK.

If you did not do it already, it might help if you remove the package declaration in the java files. If your compiling class uses any other classes, they will not be compiled because of the package declaration. It happened with me once.

Again "wrong name" error when executing java program

With reference to this post
Receiving "wrong name" NoClassDefFoundError when executing a Java program from the command-line
I did not understand how to solve the problem
Actually in my java source code there' s line :
package es_2011;
when I compile the program through JCreator everything works perfectly.
It creates a folder named es_2011 where to put .class files.
Also the executing operation goes smoothly, the program runs ok.
Now I'd like to use the command line only.
So I placed my java file in the directory where javac.exe is but whenever I try to compile I get the same error
The command I use is: javac ProgAudioJ.java
The path (where javac.exe is ) is : C:\Program files\Java\jdk1.6.0_22\bin
Is someone willing to help me understand in terms of exactly tell me what I have to do?
thanks very much...MAX

The setup used for the looks like this (under windows)
C:\classDir -> is the project
C:\classDir\testpackage -> is the only package used (the package "testpackage")
C:\classDir\testpackage\Main.class -> is the class with the main method inside (important: it is the .class and not .java)
The Main.class looks like following:
package testpackage;
public class Main {
public static void main(String[] args) {
System.out.println("Program started! ;-)");
}
}
go with your command prompt to:
c:\classDir> java testpackage.Main
the result:
Program started! ;-)
According to your problems that it starts in your IDE but not from the console:
- checked if you realy use the path to the .class files?
- with the console go to the directory of you .class files, not the project (e.g. in Eclipse it is the bin directory
- enter the full qualified class name (including packages seperated by . -> e.g. testpackage.Main

Hope it helped

MAX, if the class defines that it's inside the package es_2011, then it should be in a folder with the same name.
So in your case, put the ProgAudioJ.java in the folder es_2011 and then run
javac es_2011\ProgAudioJ.java
latter to run it, you need the command
java es_2011.ProgAudioJ

You should add javac.exe in your path .Edit your path variable and append path to jdk's bin
then put java file in a dir named es_2011 , as the package declaration is es_2011 then compile
c:\es_2011\javac YourJava.java
and now go back to C:
c:\java es_2001.Yourjava

After reading you other Post: "Receiving "wrong name" NoClassDefFoundError when executing a Java program from the command-line" I guess you go to the directory es_2011 where your ProgAudioJ.class file is located and run
java ProgAudioJ
from that folder.
instaend you have to go to the folder above (cd ..) and run
java es_2011.ProgAudioJ

Each package in Java corresponds to a folder on the filesystem. So a package declaration such as com.stackoverflow would mean that the source classes need to be in a folder ./com/stackoverflow. Typically the whole project would have a separate src folder containing com/stackoverflow.
When you compile the Java classes you DO NOT need to put source files in the same directory as javac.exe, you do however need to make sure that javac.exe is in your operating systems PATH variable. This tells the operating system where it should look for executable files when a command is run, on a *nix machine this would usually be /usr/bin or just /bin but on Windows machine the executables normally live within the applications own directories, that is C:\Program Files\something. Assuming that you've installed JDK correctly, the javac.exe should already be in the PATH you can check this by opening the command line and just running javac (just like that). If you get some output then all is well, the system knows where to find javac.exe.
Next you will need to go to your project folder and type javac -d . src/com/stackoverflow/MainSO.java notice that is run from the project folder. This will create a folder called com in your project root and put the compiled classes in com/stackoverflow. The -d flag tells javac where to put the compiled classes, if you leave that out, the compiled classes will be where the sources are.
Then when you want to run the classes you type java com.stackoverflow.MainSO (no .class). Crucially this command will need to be ran in the directory that contains the root of the class hierarchy (that is the com folder containing the compiled classes). You can specify other places for java to look for the classes by providing a classpath to the java command with the -cp flag. By default the classpath will contain the directory the java command was ran in. Should your project have dependencies external .jar files for example you will need to provide every single one of them (with their full filepath) in the classpath (this goes for the compiler as well). The IDEs do this automatically for you.
Hope that helps.

Can't Run JAR Files

I can run my project through netbeans but after I make a jar file and double click it I get the error cannot find Java runtime environment? I am on Windows.

You don't have a file associate created. Right click on the .jar file in Internet Explorer, select Open With, and navigate to your JRE. Select the java.exe executable, and make sure the command-line argument has ' -jar ' present.
The .jar file will be passed as the first argument to the JVM.

Make sure you have JRE installed.
Open the console and type java -version

You should download a Java runtime environment.

You might try, as Chris said, making sure the JRE executable is part of your PATH environment variable. Check out "4. Update the PATH variable (Optional)" from this guide.

Make sure the JRE bin dir is in your PATH env variable.

It's all about the Manifest - http://java.sun.com/docs/books/tutorial/deployment/jar/manifestindex.html

In Netbeans run the project. It will ask you what class to run (you will see a list of all the classes with a "public static void main(String[])" method). Once you do that the next time you build the class netbeans will show you how to run it (with the -jar witch). Now you should be able to double click on it.
