无法使用Maven依赖项和tycho pomConsider选项解决传递性依赖项

rey*_*n64 6 osgi eclipse-plugin pom.xml tycho maven

我尝试使用来自两个存储库的OSGI依赖关系创建一个eclipse插件，其中一个具有maven依赖关系，而另一个具有p2依赖关系：

该项目包含一个父pom.xml ummisco.gaml.extensions.parent，用于构建eclipse插件ummisco.gaml.extensions.genstar：

  • （1）ummisco.gaml.extensions.parent
    • pom.xml
  • （2）ummisco.gaml.extensions.genstar
    • pom.xml

在MANIFEST.MF这个eclipse-plugin定义这样的：

当我尝试mvn clean install进入ummisco.gaml.extensions.parent时，tycho似乎下载并识别了p2中定义的依赖关系（msi.gama.core例如）和pom.xml（core, spll,gospl, spinOSGI捆绑软件）中定义的依赖关系，但是这些捆绑软件的传递性依赖关系无法解决。

我真的不明白为什么tycho无法使用pom.xml依赖关系自动解决传递依赖关系...如果tycho识别了eclipse-plugin MANIFEST中的core，spl，spin等软件包，为什么会传递依赖关系核心，spl，spin，gospl OSGI软件包是否未下载？

您认为这个问题有解决方案吗？

更新

在此存储库之后，我尝试创建两个项目：

  • maven-bundle 将所有依赖项捆绑到一个大罐子中
  • tycho-bundle这maven-bundle依赖于此

当我在GUI模式下编译时，Intellij Idea发现了不同的依赖关系类，但是当我运行时却没有找到我的Maven项目mvn install，这真的很奇怪……我不知道问题出在哪里。

您可以在此处找到项目的存档，需要将其mvn clean install pom.xml放入/maven-bundle/文件夹，然后再mvn clean install pom.xml放入tycho-bundle/文件夹。
