Spring Boot 应用程序不会从 Eclipse 启动，但可以从 Cygwin 运行

Question

我开始从头开始开发 Spring Boot 应用程序，并按照 [http://spring.io/guides/gs/convert-jar-to-war/] 中的描述对其进行配置。

可以从 Cygwin 和 Eclipse 运行它。 但是当我尝试将依赖项添加到我的 gradle.build 中的另一个项目时出现问题。

我已将 compile(project(':my.another.project')) 添加到 gradle.build 的依赖项部分，从那时起这是不可能的从 Eclipse 运行它。但是从 cygwin 开始一切正常。

我尝试将依赖项更改为其他项目，但仍然存在相同的错误。当我删除所有依赖项时，一切正常。

所以，基本上在 Cygwin 中一切正常，当项目依赖于另一个项目时，它在 Eclipse 中失败。 你知道我哪里有问题吗？

添加额外项目时是否更改了 Eclipse 元数据？您需要告诉 Eclipse 您的项目依赖于额外的项目（例如，如果您最初是这样做的，则使用 gradle cleanEclipse eclipse）。
