title: Do multiple Eclipse-based IDEs conflict with each other?
body: <p>Based on a <a href="https://softwareengineering.stackexchange.com/questions/118954/how-do-i-develop-in-more-languages-with-less-ides">previous question, where I asked about IDEs to support development in multiple languages</a>, Eclipse and Eclipse-based IDEs were mentioned in some of the answers. If I were to use these tools, would there be conflicts between them, or can they run side by side smoothly? Is it also possible to run different Eclipse instances with seperate plugins installed in each one?</p>
