Eclipse Console not showing output

Question

I have written a simple class having an SOP statement for "Hello World". But the Eclipse console is not showing output. I then wrote the same program in a previously created project and it worked fine. I am opening the Console as given below:

Window->Show View->Console.

But it is not working. I am using j2ee project in the same workspace. Any idea? Please help. I am stuck because of this problem.

share screenshot of your problem that you are facing. How some can know what issue you having if they don't see it. – Baeza

Check that the right main is executed. And that there is no redirection (System.setOut...)). – Wardship

@ShaU Not yet.I am trying to resolve it. – Sinker

you share screenshot? or any more details. – Tollgate

Closing the Console tab and reopening it with Window->Show View->Console might also help. – Bidet

Answer 1

Go to "Window > Reset Perspective", that will reset the window settings to default. Next, you might need to stop any running Java processes. I suggest you then click "Remove all Terminated Launches" and if the red "Terminate All" is still available click that as well

Answer 2

[working] I encountered the same problem, I tried with all the solutions provided above but it didn't work then I came to a solution which worked. Follow the following process to overcome the problem.

Right click on workspace provided by Eclipse --> Select "Run As" --> Java Application.

This will work definitely.

Answer 3

I've lost the console only in the Java default perspective and I wasn't able to show it again by using window > show view > console.

What I did is the following :

1. window > Perspective > reset perspective
2. window > show view > console

and It appears now!!

Make sure that the project structure should be as follows:

Answer 5

Make sure that your System.out.println("Hello World") is in main method with proper signature.

Ex:

public static void main(String[] args){
System.out.println("Hello World");
}

Answer 6

None of the above. What helped in my case:

Run > Run configurations > Common > uncheck Launch in background (last tab all the way at the bottom).

Then it showed the error why the thing wouldnt start.

In my case: a project dependency to a project which I had closed.

See (rightclick) Project > Build path > Configure build path.

Double-check you actually saved your file. Many of us forget to save the file and simply hit run.

Answer 10

Sometimes it is possible that number of character console can accomodate is beyond capacity, so increase the buffer size of console. windows>prefences>console -increase buffer size

Answer 11

I had the same problem just figured out the solution. Just check your main method it would be

public void main(String[] args){ 

just change it to this:

public static void main(String[] args){

Answer 14

If eclipse is not showing path,

Please click on RUN-> Run configuration->click on environment tab->click on New-> add a path variable as mingw_path(if compiler is mingw in case of c++ ) and set value as C:\MinGw\bin (please check ur mingw bin path then only set).
