{{From|https://help.ubuntu.com/community/EclipseIDE}} {{Languages|php5}} Parent page: [[UbuntuHelp:Programming| Programming Applications]] === Eclipse in Breezy === ==== Eclipse download & installation ==== Install the <code><nowiki>eclipse-jdt</nowiki></code> package. The Help system is currently unavailable within Eclipse. If you have problems using the PyDev plugin, try installing Sun Java (see RestrictedFormats) and editing /etc/eclipse/java_home to include the path /usr/lib/jvm/java-1.5.0-sun (for dapper). You may also enjoy a speed up after doing that. ==== Eclipse and Sun Java ==== By default, the eclipse which is packaged with Breezy runs with the GCJ JVM and not the JVM supplied by Sun Microsystems even if you have installed the Sun version (sun-java5 packages from the Multiverse repository). In order to load eclipse with the Sun JVM, edit the /etc/eclipse/java_home file and add the path of the Sun JVM (its usually /usr/lib/jvm/java-1.5.0-sun) on the first line. Ensure that the change has happened by looking at the ''Configuration details'' from the ''About'' menu item in Eclipse. Even after setting up Eclipse to use the Sun JVM, it will by default use GCJ JRE for compiling projects. To change this JRE, goto ''Window->Preferences->Java->Installed JREs'' from inside Eclipse and make it point to the Sun JRE. ==== Java3d ==== Java3d is now supported for use with Eclipse on Ubuntu, see Java3dUbuntu. ==== Troubleshooting ==== ===== Installing plugins (ie CDT) ===== To install plugins for eclipse in Ubuntu (ie CDT), start Eclipse as root and install the plugins via the Eclipse update manager. <pre><nowiki> gksudo eclipse </nowiki></pre> ===== Plugins not working properly ===== Some plugins do not seem to function properly when running Eclipse normally, such as [http://www.eclipse.org/birt BIRT]. Running Eclipse with the following options may fix the plugin: <pre><nowiki> eclipse -vm $JAVA_HOME/bin/java -ws gtk </nowiki></pre> === Eclipse before Breezy === ==== Eclipse download ==== Go to the [http://www.eclipse.org/downloads/index.php nearest eclipse mirror] and download ''eclipse-platform-3.1.2-linux-gtk.zip''. If you want to code in Java, you can download ''eclipse-SDK-3.1.2-linux-gtk.zip'' instead or install it afterwards. ==== Eclipse installation ==== ===== Java Implementation ===== Eclipse may not be fully operational when used with free Java implementations. If you encounter problems with Eclipse after install, you may require Sun's non-free implementation to get Eclipse working properly. See instructions here: [[UbuntuHelp:Java]], but be sure to consider legal issues as well: RestrictedFormats. ===== Global installation ===== Use this method if you want Eclipse to be available for all users, or if you are the only user of the computer. ====== Eclipse ====== * Unzip eclipse in <code><nowiki>/opt</nowiki></code>: <pre><nowiki> $ sudo unzip eclipse-SDK-3.1.2-linux-gtk.zip -d /opt </nowiki></pre> * Change the owner to root: <pre><nowiki> $ sudo chown -R root:root /opt/eclipse/ </nowiki></pre> * Create <code><nowiki>/usr/bin/eclipse</nowiki></code> with your favorite text editor (e.g <code><nowiki>sudo vi /usr/bin/eclipse</nowiki></code>) and add the following content: <pre><nowiki> #!/bin/sh export MOZILLA_FIVE_HOME="/usr/lib/mozilla/" export ECLIPSE_HOME="/opt/eclipse" $ECLIPSE_HOME/eclipse $* </nowiki></pre> * Finally, allow the script to be executed: <pre><nowiki> $ sudo chmod +x /usr/bin/eclipse </nowiki></pre> ====== Gnome icon ====== * Create a new launcher on the desktop (right click on the desktop -> Create Launcher) or on a panel (right click on a panel -> Add to Panel -> Custom Application Launcher) and add the following data: ** Name: <code><nowiki>Eclipse Platform</nowiki></code> ** Command: <code><nowiki>eclipse</nowiki></code> ** Icon: <code><nowiki>/opt/eclipse/icon.xpm</nowiki></code> If you want an icon in the Applications Menu: * Create a new launcher called <code><nowiki>eclipse.desktop</nowiki></code> in <code><nowiki>/usr/share/applications</nowiki></code> with your favorite text editor (e.g <code><nowiki>sudo vi /usr/share/applications/eclipse.desktop</nowiki></code>) and add the following content: <pre><nowiki> [Desktop Entry] Encoding=UTF-8 Name=Eclipse Platform Comment=Eclipse IDE Exec=eclipse Icon=/opt/eclipse/icon.xpm Terminal=false Type=Application Categories=GNOME;Application;Development; StartupNotify=true </nowiki></pre> ===== User installation ===== Use this method if you want Eclipse available only for yourself, or if you haven't got root access to the computer. ====== Eclipse ====== * Make an opt folder in your home directory: <pre><nowiki> $ mkdir ~/opt </nowiki></pre> * Unzip eclipse in the opt folder: <pre><nowiki> $ unzip eclipse-platform-3.1.2-linux-gtk.zip -d ~/opt </nowiki></pre> * Make a bin folder in your home directory, this will be used for the startup script: <pre><nowiki> $ mkdir ~/bin </nowiki></pre> * Create <code><nowiki>~/bin/eclipse</nowiki></code> with your favorite text editor (e.g <code><nowiki>vi ~/bin/eclipse</nowiki></code>) and add the following content: <pre><nowiki> #!/bin/sh export MOZILLA_FIVE_HOME="/usr/lib/mozilla/" export ECLIPSE_HOME="$HOME/opt/eclipse" $ECLIPSE_HOME/eclipse $* </nowiki></pre> * Finally, allow the script to be executed: <pre><nowiki> $ chmod +x ~/bin/eclipse </nowiki></pre> ====== Gnome icon ====== * Create a new launcher on the desktop (right click on the desktop -> Create Launcher) or on a panel (right click on a panel -> Add to Panel -> Custom Application Launcher) ** Name: <code><nowiki>Eclipse Platform</nowiki></code> ** Command: <code><nowiki>/home/<your username>/bin/eclipse</nowiki></code> ** Icon: <code><nowiki>/home/<your username>/opt/eclipse/icon.xpm</nowiki></code> ==== Troubleshooting ==== If the following error is encountered when running eclipse from the launcher: <pre><nowiki> The Eclipse executable launcher was unable to locate its companion startup.jar file (in the same directory as the executable) </nowiki></pre> * Edit <code><nowiki>/usr/bin/eclipse</nowiki></code> with a text editor (e.g <code><nowiki>sudo gedit /usr/bin/eclipse</nowiki></code>) and change the content to the following: <pre><nowiki> #!/bin/sh # Eclipse startup script # JPackage Project <http://www.jpackage.org/> # $Id$ ECLIPSE_OPTS="" VM_OPTS="" # Source system prefs if [ -r /etc/eclipse.conf ] ; then . /etc/eclipse.conf fi # Source user prefs if [ -r $HOME/.eclipserc ] ; then . $HOME/.eclipserc fi # Set data dir if -data wasn't given. if ! echo $@ | grep '\-data ' >/dev/null 2>&1 && [ -n "$USER_DIR" ]; then ECLIPSE_OPTS="$ECLIPSE_OPTS -data $USER_DIR" fi # Find our JVM. # if [ ! -x "$JAVACMD" -a -r /usr/share/java-utils/java-functions ]; then # . /usr/share/java-utils/java-functions # set_javacmd # fi JAVACMD="/usr/lib/j2re1.5-sun/bin/java" # Set JVM if -vm wasn't given. if ! echo $@ | grep '\-vm ' >/dev/null 2>&1 && [ -n "$JAVACMD" ]; then ECLIPSE_OPTS="$ECLIPSE_OPTS -vm $JAVACMD" fi # Set JVM args if -vmargs wasn't given. This needs to be the last option. if ! echo $@ | grep '\-vmargs ' >/dev/null 2>&1 && [ -n "$VM_ARGS" ]; then VM_OPTS="-vmargs $VM_ARGS" fi # if [ -w $USER_DIR/.metadata/.config/platform.cfg ]; then # perl -p -i.bak -e 's|^site\.[0-9]*\.list\.[0-9]*=.*\n||g;' $USER_DIR/.metadata/.config/platform.cfg # fi /opt/eclipse/eclipse $ECLIPSE_OPTS $@ $VM_OPTS </nowiki></pre> * Source: http://www.karakas-online.de/forum/viewtopic.php?t=2565 ---- CategoryDocumentation [[category:UbuntuHelp]]
