Eclipse in Breezy

Eclipse download & installation

Eclipse 3.0.1 has been uploaded to Breezy. Finally. You should be able to simply apt-get install it.

Actually these breezy packages should build fine for Hoary too. You can probably just apt-get source them and let it rip.

The Help system has been disabled completely because we don't yet have a free Tomcat. Working on that. Enjoy.

apt-get install eclipse-jdt

Or just get it via Synaptic.

If you have problems using the PyDev plugin, try installing Sun JVM (j2re1.5-sun). Edit /etc/eclipse/java_home to include the path /usr/lib/j2re1.5-sun

Troubleshooting

Installating plugins (ie CDT)

To install plugins for eclipse in Ubuntu (ie CDT) you need to start eclipse as root and then install them via the Eclipse update manager.

gksudo eclipse

Eclipse before Breezy

Eclipse download

Go to the [http://www.eclipse.org/downloads/index.php nearest eclipse mirror] and download eclipse-platform-3.0.2-linux-gtk.zip. If you want to code in Java, you can download eclipse-SDK-3.0.2-linux-gtk.zip instead or install it afterwards.

Eclipse installation

Java Implementation

Eclipse may operate improperly when using 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: ["Java"], but be sure to consider legal issues as well: RestrictedFormats.

Global installation

Use this method if you want Eclipse available for all users, or if you are the only user of the computer.

Eclipse

• Unzip eclipse in /opt:

$ sudo unzip eclipse-SDK-3.0.2-linux-gtk.zip -d /opt

• Change the owner to root:

$ sudo chown -R root:root /opt/eclipse/

• Create /usr/bin/eclipse with your favorite text editor (e.g sudo vi /usr/bin/eclipse) and add the following content:

export MOZILLA_FIVE_HOME="/usr/lib/mozilla/"
export ECLIPSE_HOME="/opt/eclipse"

$ECLIPSE_HOME/eclipse $*

• Finally, allow the script to be executed:

$ sudo chmod +x /usr/bin/eclipse

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: Eclipse Platform

  • Command: eclipse

  • Icon: /opt/eclipse/icon.xpm

If you want an icon in the Applications Menu:

• Create a new launcher called eclipse.desktop in /usr/share/applications with your favorite text editor (e.g sudo vi /usr/share/applications/eclipse.desktop) and add the following content:

[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

User installation

Use this method if you want Eclipse available only for yourself, or if you haven't root access to the computer.

Eclipse

• Make a personnal opt folder in your home directory:

$ mkdir ~/opt

• Unzip eclipse in the opt folder:

$ unzip eclipse-platform-3.0.2-linux-gtk.zip -d ~/opt

• Make a bin folder in your home directory, this will be used for the startup script:

$ mkdir ~/bin

• Create ~/bin/eclipse with your favorite text editor (e.g vi ~/bin/eclipse) and add the following content:

export MOZILLA_FIVE_HOME="/usr/lib/mozilla/"
export ECLIPSE_HOME="$HOME/opt/eclipse"

$ECLIPSE_HOME/eclipse $*

• Finally, allow the script to be executed:

$ chmod +x ~/bin/eclipse

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: Eclipse Platform

  • Command: /home/<your username>/bin/eclipse

  • Icon: /home/<your username>/opt/eclipse/icon.xpm

Troubleshooting

If the following error is encountered when running eclipse from the launcher:

The Eclipse executable launcher was unable to locate its companion startup.jar file (in the same directory as the executable)

• Edit /usr/bin/eclipse with a text editor (e.g sudo gedit /usr/bin/eclipse) and change the content to the following:

# 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

Why is it necessary to add the variable for MOZILLA_FIVE_HOME? Is this so eclipse can use Firefox as its internal browser?
