A list of FAQs gathered on IRC #eclipse and #eclipse-dev on freenode

Q: What are those channels about?

A: #eclipse-dev is about development *of* Eclipse (for development *with* Eclipse, please see #eclipse)

A: #eclipse is about development *with* Eclipse (for development *of* Eclipse, please see #eclipse-dev)

Q: Are there other active channels about Eclipse (in alphabetic order)?

A: #azureus about Azureus, an Eclipse-based bittorrent client

A: #easyeclipse about EasyEclipse, an Eclipse distribution

A: #eclipseSTP about the Eclipse SOA tools project (active only on wednesday mornings PST time)

A: #phpeclipse about PHPEclipse, an Eclipse-based IDE for PHP

A: #radrails about RadRails, an Eclipse plug-in for Ruby on Rails development

A: #rssowl about RSSOwl, an Eclipse-based RSS reader

A: #subclipse about Subclipse, a Subversion plugin

A: #udig about UDIG, an Eclipse-based GIS toolkit

A: #weblogic-eclipse about the Webglogic plug-in

A: Check also (listed in alphabetic order): #debian-java, #fedora-java, #gentoo-java and #ubuntu-java : those channels are often dealing with Eclipse on Linux questions.

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

A: #eclipse, most of the time, 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 deasl with that programming language.

Q: Nobody is answering my question. What should I do?

A: First be patient, the person that has an answer for you may be busy at the moment. Then be patient, that person may be in another time zone. Be polite and gentle. Or else, you will be politely ignored. If nobody answers, it may just be that nobody knows the answer. You will have to make some research on your own. The Eclipse newsgroups are a good place, as well as the Eclipse bugzilla. And search engines are your best friends Good luck! And a last word:do not hesitate to provide answers to others too!

Q: Where are Eclipse's log files?

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

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

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

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

A: Quite often, Eclipse will not work properly with non-Sun JVMs. Commonly, issues with it are 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.

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

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

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

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

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

A: There is an SWT snippet recently written that shows just how to do that here.

Q: I just installed Subversion on (Mac, Linux) then I installed Subclipse, but it does not work. What is the problem?

A: Verify that the version of Subclipse matches the version of SVN you run. Try to un-install Subversion and configure Subclipse preferences to run JavaSvn. Ask on #subclipse for more help.

Q: Where are Eclipse preferences stored?

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

Q: Where are update site bookmarks stored?

A: In <eclipse_home>/eclipse/configuration/org.eclipse.update/bookmarks.xml

Q: Where are the CVS repositories locations stored?

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

Q: Where are my eclipse plugins folder?

A: Under eclipse/plugins

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

A: Follow the instructions in the SWT FAQ. http://www.eclipse.org/swt/faq.php#browserlinux

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

A: Firefox is not supported as embded browser on Linux for now. Track this bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=72487 A: But on some Linux distro that dynamically link Firefox (like Ubuntu and Fedora), Firefox will work.

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

A: Enable JavaSvn in the Team/SVN preferences.

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

A: To get the standard java javadoc to display in hoveranmd 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.

Q: 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!

A: 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.

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

A: 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 propject properties.
