No console output in Eclipse Juno

Question

Pretty straight forward. I've been working in Eclipse Juno for a while now and my console always worked. When you output to the console with

System.out.println("Something");

In java, or just when you compile and build your project there's always some output in the console. But today, I started up the IDE, and nothing. No console output. I've restarted Eclipse, reset the perspective.. Nothing is happening.

Using the Java EE version just btw. Any help would be appreciated. Thanks!

SOLVED : So after struggling for how long, I shut down my server. Killed eclipse. And restarted everything and the console is now working again. No idea how this happened in the first place.

Answer 1

There is a small pull-down icon on the right of the console that lets you select which console you want to see. Maybe you accidentally selected a different console.

Answer 2

Go to run as and choose Run Configurations -> Common and in the Standard Input and Output configuration see if Allocate Console is selected.

Run Configurations:

Commons view:

Answer 3

You can just re-open the console view from Window>Show View> Console. It worked for me, just before posting the answer here.

Answer 4

for this same i did the following things and it's worked for me

Here's what i did:

[1] Uninstall - Removed all traces of Eclipse (64-bit). - Removed all traces of MinGW (and/or Cygwin). - Removed all traces of Java (SDK and JRE).

[2] Restart PC

[3] Install - Installed latest Java JDK (includes the JRE) 32-bit. - Installed Eclipse IDE (Java Edition) 32-bit. - Installed MinGW (with Msys). - Installed the necessary CDT tools from within Eclipse.

And it works fine!

For installation compiler/CDT installation, i followed this guide (making my own alterations where needed): http://max.berger.name/howto/cdt/cdt.jsp

Hope it works for you! And thanks for the tip-off that it was working 100% on a 32-bit machine. Very Happy

Answer 7

For me, using eclipse-luna the problem was related to a specific workspace. Whenever I used this workspace, one specific plugin failed to do console-output. I re-installed the plugin, I even re.installed eclipse itself and whiped out the ".eclipse-luna" folder, but the problem still was there.

I finally fixed the problem by deleting the folder ".metadata" in this workspace.

I also had no output in the console after some error. The answer from Narendra Pathai worked for me.

1. Deselect the Allocate Console

2. Run the application => I got output in my console directly

3. Select it again

After doing that, I got output.

Answer 9
