Although many software development projects have moved their developer discussion forums to Stack Overflow, Eclipse has been steadfast in hosting their self-supported community forums. However, recent studies show that having a forum seem to share similarities to other communication channels. In this paper, we would like to investigate how the Eclipse project has successfully maintained its forum. Using a mixed-methods approach, we investigate the participation, discussions, and interactions between members of the Eclipse project by empirically analyzing over 1 million forum threads and their linkages to four systems with 2,170 connected contributors within the Eclipse ecosystem. Our results show that forum members actively participate in posting and responding to the threads equally. The forums are dominated by question and answer threads, with the status of user is likely relate to topics discussed. Sentiment among developers are consistent, with interaction among developers that are neutral or positive. Thus, for users, we recommend to identify appropriate topics and ask in a positive way when joining forums. Considering to prepare project-specific forums, such as GitHub Discussions, is recommended for software development projects to share such closed information. For researchers and practitioners, our study on forums is just one example of how Eclipse has been successful in sustaining a healthy ecosystem.

维持健康的生态系统：Eclipse 论坛中的参与、讨论和互动

尽管许多软件开发项目已将其开发人员讨论论坛移至 Stack Overflow，但 Eclipse 一直坚定不移地托管其自支持的社区论坛。然而，最近的研究表明，拥有一个论坛似乎与其他沟通渠道有相似之处。在本文中，我们想调查 Eclipse 项目如何成功维护其论坛。我们使用混合方法，通过实证分析超过 100 万个论坛帖子及其与 Eclipse 生态系统中 2,170 名相关贡献者的四个系统的联系，调查了 Eclipse 项目成员之间的参与、讨论和互动。我们的结果表明，论坛成员积极参与发帖和回复帖子。论坛以问答为主，与用户的状态很可能与讨论的主题有关。开发人员之间的情绪是一致的，开发人员之间的互动是中性或积极的。因此，对于用户，我们建议在加入论坛时确定合适的主题并以积极的方式提问。考虑准备项目特定的论坛，例如GitHub Discussions，建议软件开发项目共享此类封闭信息。对于研究人员和从业者来说，我们对论坛的研究只是 Eclipse 如何成功维持健康生态系统的一个例子。考虑准备项目特定的论坛，例如GitHub Discussions，建议软件开发项目共享此类封闭信息。对于研究人员和从业者来说，我们对论坛的研究只是 Eclipse 如何成功维持健康生态系统的一个例子。考虑准备项目特定的论坛，例如GitHub Discussions，建议软件开发项目共享此类封闭信息。对于研究人员和从业者来说，我们对论坛的研究只是 Eclipse 如何成功维持健康生态系统的一个例子。
