I have been using Eclipse IDE for a long time. Its a really great IDE for Java/C/C++ (and other languages with its THOUSANDS of plugins). Every once in a while, I get the need for creating a Javax interface. To do this normally, I would setup the new java project then add what I need. But, wouldn't it be nice if I could just make a template project to automatically include the code for the files. How would I go about doing this? It it even possible? The Eclipse CDT can make a new project type. So can the Google ADT and Google App engine. So I would imagine it is possible. But how?
You must write your Eclipse plug-in that implements org.eclipse.ui.newWizards extension point. You can extend an existing "New Java Project" wizard, and provide your custom project layout implementation (see the API).
Regarding java projects you might be familiar with maven. Maven offers of project template mechanism called archetypes. I never created an own archetype but the explanation to do this (Guide to Creating Archetypes) does not seems to be so complicated.
So although this is not a special eclipse solution it might be helpful for you. Together with the m2eclipse plugin it also works nice together with eclipse.
