A collection of FAQs gathered in the Eclipse IRC channels.

Contents

General

What are #eclipse and #eclipse-dev about?

  • #eclipse is about development with Eclipse (for development of Eclipse, please see #eclipse-dev).
  • #eclipse-dev is about development of Eclipse (for development with Eclipse, please see #eclipse).

Are there other active channels about Eclipse?

  • #azureus about Azureus, an Eclipse-based BitTorrent client
  • #easyeclipse about EasyEclipse, an Eclipse distribution
  • #phpeclipse about PHPEclipse, an Eclipse-based IDE for PHP
  • #radrails about RadRails, an Eclipse plug-in for Ruby on Rails development
  • #rssowl about RSSOwl, an Eclipse-based RSS reader
  • #subclipse about Subclipse, a Subversion plug-in
  • #udig about UDIG, an Eclipse-based GIS toolkit
  • #weblogic-eclipse about the Webglogic plug-in

If you are using Linux, please consider visiting #debian-java, #fedora-java, #gentoo-java, and #ubuntu-java for distribution-specific questions.

I am looking for help with developing with Eclipse. Should I ask on #eclipse or #eclipse-dev?

Probably #eclipse as long as your question relates to Eclipse usage. If the issue is purely a language issue unrelated to Eclipse, you should find a more appropriate channel that deals with that programming language. For example, freenode has a ##java channel for Java-related questions.

Nobody is answering my question. What should I do?

First, be patient, the person that has an answer for you may be busy at the moment. Then please continue being patient as that person may be in another time zone. Be polite and gentle or you may be politely ignored. If nobody answers, it may just be that nobody knows the answer. You will have to do some research on your own. The Eclipse newsgroups are a good place, as well as the Eclipse Bugzilla. Remember that search engines are your best friends, and good luck! For those that have some idea of a possible solution, please do not hesitate to speak up!

Eclipse

Where are Eclipse's log files located at?

  • <workspace>/.metadata/.log
  • <eclipse install>/configuration/<sometimestamp>.log
  • <eclipse install>/configuration/org.eclipse.update/install.log

I am working on a project and doing something or other does not work. Where should I start?

First, clean your projects using the menu item Project/Clean to trigger a rebuild.

Where are Eclipse preferences stored?

If you want to keep preferences from one version to the other, export them using File/Export/Preferences.

Preferences are stored in various places (this applies to Eclipse 3.1)

  • for each installation (but this may vary for multi-user installations), in files stored in <eclipse_home>/eclipse/configuration/.settings/ . There is typically one file per plugin, with a prefs extension. Note that very few plug-ins use installation-wide preferences.
  • for each workspace, in files stored in <workspace>/.metadata/.plugin/org.eclipse.core.runtime/.settings . There is typically one file per plugin, with a prefs extension.
  • for each project --for project-level settings -- in files stored in a .settings sub-directory of your project folder

Where are update site bookmarks stored?

It is within an XML file called <user_home>/.eclipse/org.eclipse.platform_3.1.2/configuration/org.eclipse.update/bookmarks.xml. Your Eclipse version may vary.

Where are my eclipse plug-ins folder?

The plug-ins folder is <eclipse_home>/plugins.

The javadoc for the standard Java classes does not show up as context help. What is the problem? Should I download the javadocs?

To get the standard java javadoc to display in hover and context help in the Eclipse java editor, you need to run a JDK . Eclipse retrieves the javadoc from the JDK java sources. The sources are bundled with a JDK but not with a JRE. The file containing the sources in the SUN JDK is src.zip.

But what do you mean by 'run a JDK'? the problem is that I've got unpacked java docs (and in archive too) at the proper location in the JDK dir and it is not displayed when working on java project...moreover javadoc specific to project is shown properly!

You need either to have the JDK set as the Java Runtime for your project or workspace, or have started Eclipse with that JDK. Make sure that the root dir of your JDK installation contains a file called src.zip.

But it still does *not* work! Help me!

Make sure that you have selected the JDK in your workspace or project preferences. For the workspace check: windows->preferences->installed JRE's , For the project check the project properties.


Installation

I just installed Eclipse on Linux, but it does not start. What is the problem?

Quite often, Eclipse will not work properly with non-Sun JVMs. These issues are usually related to Blackdown or GCJ. Try installing a Sun JVM and make sure that is the one being used by starting Eclipse with the argument: eclipse -vm /full/path/to/java/bin/java . The argument must point to the java or javaw executable.

I just installed Eclipse on Linux 64, but it does not start. What is the problem?

Make sure that you have downloaded the 64-bit version of Eclipse and have installed a Sun 64-bit JVM


SWT

I cannot get the SWT widget ABC to work when I do XYZ. Could you help me?

Check the SWT Snippets section, there might be a code example that demonstrates what you are trying to do.here.

I cannot get Mozilla to run on Linux as an embedded browser?

Follow the instructions in the SWT FAQ.

I cannot get Firefox to run on Linux as an embedded browser?

Firefox is not supported as embedded browser on Linux for now. Take a look at bug #72487.

On some Linux distributions that dynamically link Firefox (like Ubuntu and Fedora), Firefox will work.


Version Control

I just installed Subversion on Mac/Linux, and then I installed Subclipse, but it does not work. What is the problem?

Verify that the version of Subclipse matches the version of Subversion that you have installed. Try uninstalling Subversion and configuring Subclipse's preferences to run JavaSVN. Take a look at the Subclipse FAQ. Ask on #subclipse for additional assistance.

Where are the CVS repositories locations stored?

In <workspace>/.metadata/.plugin/org.eclipse.team.cvs.ui/repositoriesView.xml . Previously used commit comments are in commitCommentHistory.xml.

I am trying to use svn+ssh:// with Subclipse, and it does not work?

Generally speaking, the JavaSVN adapter in the Team/SVN preferences will yield better results when using svn+ssh. See: Subclipse support for SVN protocols for detailed information.

I am having some trouble with CVS in eclipse -- is there a way I can get actual logs and see detailed error messages?

Open the console view and select CVS from the triangle drop-down in the console toolbar.
