我正在创建一些需要第三方插件和功能的 Eclipse 插件和功能。为了将这些依赖项包含到我的项目中，我创建了一个 p2 布局存储库。
注意：我的 p2 工件不是 Maven 项目...但是，我正在使用 Maven 风格构建。这是 p2 存储库的 pom.xml
<properties>
<tycho-version>0.18.0</tycho-version>

<repositories>
<repository>
<id>eclipse-platform-m6</id>
<layout>p2</layout>

</configuration>
</plugin>
<plugin><!-- enable the Tycho build extension -->
<groupId>org.eclipse.tycho</groupId>
<artifactId>tycho-maven-plugin</artifactId>
<version>${tycho-version}</version>
<extensions>true</extensions>
</plugin>
</plugins>
</build>
以上构建成功，并创建（并验证）p2 存储库。我在我的中得到以下结构target/项目目录
- Project
..
..
- target
- p2agent
- org.eclipse.equinox.p2.core
- org.eclipse.equinox.p2.engine
- repository
- features
- plugins
artifacts.xml
content.xml
<projectname>-<version>.zip <!-- This contains same things as repository directory here -->
现在，我使用 Tycho 来构建我的插件和功能，并引用我上面创建的 p2 存储库。我的插件和功能有以下项目结构
- bundle.parent
- bundle.mainplugin
- bundle.mainplugin.test.fragment
- bundle.mainplugin.feature
这是我的bundle.parent pom.xml

<groupId>org.eclipse.tycho</groupId>
<artifactId>tycho-maven-plugin</artifactId>
<version>${tycho-version}</version>
<extensions>true</extensions>
</plugin>
</plugins>
</build>
最后，我运行目标mvn clean install在父 pom.xml 上。很遗憾，mvn-compile当我的插件中的类扩展插件中的某些类时，会引发编译问题。 （运行时也需要这些类）。这是错误：

我的问题：
从编译器错误来看，我相信第谷在某种程度上没有让这些第三方工件可供我存在编译器错误的类使用。有没有办法确定我的插件类是否存在于第谷类路径中？
UPDATE
检查了我希望在第谷反应器中可用的第三方捆绑包的可用性这个位置 http://wiki.eclipse.org/Tycho/Target_Platform#Locally_built_artifacts
java -jar /home/.../eclipse-3.8.2/plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar -debug -consolelog -application org.eclipse.equinox.p2.director -repository file:///home/../target/repository -list
所有第三方捆绑包均已成功显示。
