add vaadin to a new project in Eclipse without maven

Hello,
I have an existing project using vaadin, but this project doesn’t use any build systems (maven, gradle, ant…). It was built manually. Now i have to move it to my developer pc, and i have to start from a new project and add everything manually.
I dont understand how to add vaadin to a new project without maven in Eclipse. Can anybody help?

I would suggest that you can create a new project by using some vaadin maven archetypes see
vaadin maven archytypes

Then just copy your old code the corresponding places in the new project.

Haijian, thank you for your answer, I also think it’s a good solution, the problem in using maven in this project was because maven downloads dependencies from internet, but our proxy server cuts traffic. That’s because our developers didn’t use maven. Today I implemented a simple getting started vaadin project without maven, by connecting user libraries. I think, I’ll go through it, thank you.
