I am the author of an open source project and I am currently developing a java development framework called Mars-java. An open source project, as its name implies, is a completely open source project, meaning that it is completely free to use and anyone can read and use the source code project, which is a non-profit product. The goal of the project is to lower the development threshold of java and reduce the development difficulty as much as possible, And provide as many new features as possible. but all of this takes time and money. If I can achieve my wish, I will have enough time and energy to get in and let the project go further.
