How to Install Eclipse on Ubuntu
Eclipse is an open source community whose projects are focused on building an open development platform comprised of extensible frameworks, tools and runtimes for building, deploying and managing software across the lifecycle. A large and vibrant ecosystem of major technology vendors, innovative start-ups, universities, research institutions and individuals extend, complement and support the Eclipse platform.
Installing Eclipse,Sun Java in Ubuntu
sudo apt-get install eclipse sun-java6-jdk
This will install the required packages, however, Eclipse will run very slowly since it will be using GNUâ€™s java, not Sunâ€™s. We now need to make Sunâ€™s java the default.
sudo update-java-alternatives -s java-6-sun
Next, edit the JVM configuration file
sudo -b gedit /etc/jvm
and add the following to the top of the file
There is a bug right now were Eclipse ignores Ubuntuâ€™s java-common settings and uses its own (bug 45347). To work around the bug, you need to edit Eclipseâ€™s java_home file
sudo -b gedit /etc/eclipse/java_home
to the top of the file.
Lastly, if you have lots of memory you may want to increase the heap size (warning: If you make the heap size too large then parts of eclipse will continuously swap in and out.).The settings can be altered by editing the eclipse.ini file.
For feisty users:
sudo -b gedit /usr/lib/eclipse/eclipse.ini
The argument Xms refers to the minimum heap size and Xmx refers to the maximum heap size.
