Eclipse - An open-source, platform-independent software framework. 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. The classic Eclipse package contains: the Eclipse Platform, Java Development Tools, and Plug-in Development Environment, including source and both user and programmer documentation. Upgrading: if you find an error during Eclipse initialization, check this two files: /opt/eclipse/configuration/config.ini /opt/eclipse/eclipse.ini If you haven't done modifications in those files, overwrite them with config.ini.new and eclipse.ini.new.
