Class couldn't have been found
I'm trying to compile a plugin but somehow it says the following:
Error: The main class ToDoList was not found or loaded
Caused by: java.lang.ClassNotFoundException: ToDoList
I could compile plugins before but now i cannot do it anymore with any plugin. I've been researching and trying possible ways to fix it but i can't manage to do it.
This is the part of the code:
Thanks in advance.71 Replies

How do you compile your code? Are you in the correct directory? Is the classpath set up correctly?
To compile it i press the f5 key
How can i check the classpath?
If it's the bin folder, yeah i think so
Pressing F5 should show the executed command in the console. Can you copy this here?
& 'C:\Program Files\Eclipse Adoptium\jdk-17.0.15.6-hotspot\bin\java.exe' '-agentlib:jdwp=transport=dt_socket,server=n,suspend=y,address=localhost:51486' '-XX:+ShowCodeDetailsInExceptionMessages' '-cp' 'C:\Users\AppData\Roaming\Code\User\workspaceStorage\d646ddf4c7bc51033a126ed95050159c\redhat.java\jdt_ws\jdt.ls-java-project\bin' 'ToDoList'

"Create Java Project"
what project type?
it was working before although i didnt have any project opened
What options are there?
Do you want to use any libraries?
well not for now as im currently a beginner
so i dont know about them yet
Then "No build tools" is fine
then?
i choose the Java folder? @dan1st | Daniel
What exactly does it show?
The folder where i got my projects
so open the folder where you want to make the file or create a new folder and select it
why a new window is now opened
do i close it and keep with the old one or ?
the new one is where your project is now
Check the src folder
that's where you put your classes
App.java
that one?
yes
Can i change its name?
Nice it's now working
if you also change the name of the class inside
the file name must match the class name
yeah i noticed that

yeah
I guess make sure you understand all code you are writing
