Question

我正在开发一个JavaFX e4应用程序。到目前为止，我跟着tutorials，我也得到了一个运行示例应用程序。我创建了一个新项目并包含了我的代码/视图等，从eclipse启动时应用程序运行正常。现在我想通过maven导出这个应用程序，这就是我被困住的地方。

我还需要一些外部库，它们可以作为eclipse java项目使用。其中一些项目包括Java代码（如自编的commons-lib），其他项目只包含一些jar文件。 Eclipse允许我通过feature.xml包含这些项目（只需单击“添加”）。到目前为止一切正常，当我通过'product'文件启动应用程序时，eclipse设法解决所有依赖关系并启动我的JavaFX e4应用程序而没有任何错误。

当我尝试从终端通过maven构建应用程序时，我收到以下错误：

缺少的依赖项是一个eclipse Java项目，它包含一些jar和一些Java src文件。就像我已经说过的那样，eclipse设法解决依赖关系并显示我的GUI，maven无法解决依赖关系。我不知道问题出在哪里。首先，我想到使用正确配置的pom.xml将公共项目更改为maven项目，但没有任何成功。

maven-tycho构建指向的p2存储库（默认情况下，它很可能只指向efxclipse）必须包含所需的工件。查看releng项目中的pom.xml！

经过这么多年，我找到了解决问题的方法。这是一个格式错误的清单，由maven创建（由于默认值）。请参阅此处了解解决方案Maven: prefers manifest dependencies over pom.xml dependencies
