Question

我有一个Eclipse RCP应用程序，它使用Tycho插件与Maven一起构建。有一个主POM，包含所有插件和功能作为模块。

如果我使用Maven安装主POM ，则生成的反应器构建工作正常。所有模块都已构建，安装成功。

但是，如果我单独构建一个Eclipse 插件，则依赖到应用程序的其他插件不能解决即可。

依赖第三方库（例如Eclipse平台）似乎正常工作。我们的应用程序的Eclipse插件只有这种类型的依赖项才能成功构建。

控制台输出如下：

由于反应堆构建成功，所有插件构建都在我们公司的存储库中（我们使用Artifactory）。在Artifactory Web应用程序中，我清楚地看到了preferences插件的1.8.15-SNAPSHOT版本。但是，似乎无法访问此存储库。

存储库信息在settings.xml文件中指定。请注意，已从该存储库成功检索父POM：

与其他插件有依赖关系的插件的POM.xml如下：

<project ...>
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>com.mycompany.myproduct</groupId>
    <artifactId>gui.parent</artifactId>
    <version>1.0-SNAPSHOT</version>
  </parent>
  <artifactId>com.mycompany.myproduct.gui.editors</artifactId>
  <version>1.8.15-SNAPSHOT</version>
  <packaging>eclipse-plugin</packaging>
</project>

同一个插件的MANIFEST.MF文件如下：

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: MyProduct Editors Plug-in
Bundle-SymbolicName: com.mycompany.myproduct.gui.editors;singleton:=true

Answer 1

Tycho没有查看Maven存储库来解析其依赖关系（因为Maven存储库没有足够的元数据来解析OSGi清单中指定的依赖关系）。相反，Tycho需要p2存储库来存储来自远程的工件。

因此，为了涵盖反应堆部件构建的用例，您需要执行以下操作：

让CI构建生成一个p2存储库，该存储库聚合反应堆中的所有工件，并将该p2存储库发布到静态URL。（最简单的解决方案是使用Jenkins作业并使用指向构建工作区的URL。）
在项目中创建一个配置文件，该配置文件将CI构建p2存储库添加为POM中布局为p2的存储库。

通过这种方式，即使您没有同时构建其他模块，项目的工件也将成为模块target platform的一部分。

Answer 2

我认为除了maven坐标之外，您还需要提供父级的相对路径。没有相对路径，只有当父pom已经至少在您的本地仓库中时，它才有效。
