java - 使用 Tycho/Maven 构建 RAP 会出现 DuplicateReactorIUsException

Question

我正在艰难地使用 Tycho 让 Maven 编译我的基于 OSGi 的 RAP 应用程序。我想我几乎已经把所有东西粘在一起了，但是有一个错误我无法修复，因为我不知道它来自哪里。使用工作目录根目录中的任何 Maven 命令，我都会收到以下错误:

[ERROR] Internal error: org.eclipse.tycho.p2.target.DuplicateReactorIUsException: Duplicate reactor project IUs.
[ERROR] de.andre.osgitest 0.0.1.qualifier => [C:\eclipse\modeling\pomws\de.andre.osgitest, C:\eclipse\modeling\pomws\de.andre.osgitest.product]
[ERROR] -> [Help 1]

项目结构如下:

root
|de.andre.osgitest
|  |src
|  |  | ...
|  |
|  |META-INF
|  |  | MANIFEST.MF
|  |
|  |OSGI-INF
|  |  | contribution.xml
|  |
|  |WEB-INF
|  |  | launch.ini
|  |  | web.xml
|  |
|  |- build.properties
|  |- de.andre.osgitest.launch
|  |- osgitest.target
|  |- pom.xml

|de.andre.osgitest.feature
|  |rootfiles
|  |  |lib
|  |  |  |- org.eclipse.equinox.servletbridge_1.3.0.v20140430-1556.jar

|  |- build.properties
|
|de.andre.osgitest.product
|  |- pom.xml
|  |- osgitest.product
|  |- assembly.xml
|
|- pom.xml

因为 pom.xml 对于这个线程来说太多了，我将引用 http://pastebin.com/S7AM7hbW在这里。

我希望你们中的一位聪明人有一个想法。

干杯，安德烈

看来您需要确保所有 artifactId 都是唯一的 ( http://software.2206966.n2.nabble.com/Does-artifact-id-really-have-to-be-globally-unique-0-10-regression-td5630018.html )。

我通常使用这种模式:

<groupId>com.example.product</groupId> 
<artifactId>com.example.product.bundle1</artifactId>

<groupId>com.example.product</groupId> 
<artifactId>com.example.product.bundle2</artifactId>

其中 artifactId 与 bundle Bundle-SymbolicName 匹配。
