Eclipse: Adding a new console and writing messages to it

http://www.jevon.org/wiki/writing_to_a_console_in_eclipse

MessageConsole console = new MessageConsole("Node Console", null);
console.activate();
ConsolePlugin.getDefault().getConsoleManager().addConsoles(new IConsole[]{ console });

stream.println("Hello, world!");

This is how it looks..

Remove all .svn folders recursively

For my reference...

To remove all .svn folders from your project, we can run the following command from the root of the folder.

Linking external project to eclipse workspace without really moving the project content

If you wanted to access the external eclipse project resources without really adding them into eclipse workspace, below piece code will help to do that.


 privagte void linkProject(String projectPath) throws CoreException {

IProjectDescription description = ResourcesPlugin.getWorkspace().loadProjectDescription( new Path(projectPath + File.separator +".project"));

IProject project = ResourcesPlugin.getWorkspace().getRoot().getProject(description.getName()); 
project.create(description, IProject.FORCE, null);
 if (!project.isOpen()) {
   project.open(null);
   }

Closing eclipse empty editor area

I have a use case, where I need to the close the eclipse empty editor area, so that editor area can be used by something else.

This can be achieved by implementing IPartListerner2 interface which is provided org.eclipse.ui.*

import org.eclipse.ui.IEditorInput;

import org.eclipse.ui.IEditorReference;

import org.eclipse.ui.IEditorSite;

import org.eclipse.ui.IPartListener2;

import org.eclipse.ui.IWorkbenchPage;

import org.eclipse.ui.IWorkbenchPartReference;

import org.eclipse.ui.PartInitException;

import org.eclipse.ui.editors.text.TextEditor;

public class AbstractMyEditor extends TextEditor implements IPartListener2 {

@Override

public void init(IEditorSite site, IEditorInput input) throws PartInitException {

site.getPage().addPartListener(this);

super.init(site, input);

}

@Override

public void partActivated(IWorkbenchPartReference partRef) {

}

@Override

public void partBroughtToTop(IWorkbenchPartReference partRef) {

}

@Override

public void partClosed(IWorkbenchPartReference partRef) {

IWorkbenchPage page = partRef.getPage();

if (page.isEditorAreaVisible()) {

IEditorReference[] editores = page.getEditorReferences();

if (editores.length <= 0) {

page.setEditorAreaVisible(false);

}

}

}

@Override

public void partDeactivated(IWorkbenchPartReference partRef) {

}

@Override

public void partOpened(IWorkbenchPartReference partRef) {

}

@Override

public void partHidden(IWorkbenchPartReference partRef) {

}

@Override

public void partVisible(IWorkbenchPartReference partRef) {

}

@Override

public void partInputChanged(IWorkbenchPartReference partRef) { }

}

Eclipse view id's

For my reference.

Eclipse view id's for progress view and error log view.

org.eclipse.ui.views.ProgressView
org.eclipse.pde.runtime.LogView
org.eclipse.ui.console.ConsoleView

org.eclipse.ui.views.ResourceNavigator  => IPageLayout.ID_RES_NAV

org.eclipse.ui.navigator.ProjectExplorer  => IPageLayout.ID_PROJECT_EXPLORER

-vm in eclipse.ini is not considered during the eclipse launch in mac os x

I was facing this issue, I have multiple Java versions installed in my Mac system and I wanted to change my eclipse default Java version.

I have configured -vm parameter in eclipse.ini file in mac os x, but some how this parameter didn't take effect.
-vm
Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/bin/java

To resolve this issue, I have followed the below link.
http://stackoverflow.com/questions/10352715/how-do-i-run-eclipse-using-oracles-new-1-7-jdk-for-the-mac

What worked for me is, configuring libjvm.dylib path in the eclipse.ini file and info.plist file.

eclipse.ini
-------------
-vm
Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/jre/lib/server/libjvm.dylib

info.plist
----------
<key>Eclipse</key>
<array>
<string>-vm</string>
<string>/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/jre/lib/server/libjvm.dylib</string>
</array>

Add above entry in the last.

info.plist file can be found in below location:
Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents
