【问题描述】：

我正在使用 tycho 进行构建过程。

这个项目是一个 RCP 应用程序，带有 tycho 0.21.0 和 Java 1.6 编译器。

这个项目使用了 europa 插件和功能，为了解决这个问题，我使用 featuresandbundles 发布者并将这个文件放在 Nexus 中。

在我的项目中，我有：

aggregator_project 父项目特征项目存储库项目

我正在向您发送附加的 pom 项目。

当我执行命令 mvn clean install 时，tycho 显示如下错误：

有人有办法解决这个问题吗？

【问题讨论】：

如何声明对 com.soluzionasf.arqw10.common 的依赖？您使用“必需插件”还是“导入包”
我是这个主题的新手，但我会尝试解释一下。据我了解，我拥有对 MANIFEST 文件的所有控制依赖项。但依赖项也在 plugin.xml 文件中。在这种情况下，有一个名为 com.soluzionasf.zeus 的项目，具体取决于 com.soluzionasf.arqw10.common。

标签： maven tycho

【解决方案1】：

我发现了错误原因：

访问项目 com.soluzionasf.arqw10.common 并打开 pom.xml 文件，我发现它是这样的：

<groupId> com.soluzionasf.arqw10.common </ groupId>
<artifactId> com.soluzionasf.arqw10.common </ artifactId>
<version> 1.0.0-SNAPSHOT </ version>
<packaging> jar </ packaging>

正确的是：

<groupId> com.soluzionasf.arqw10.common </ groupId>
<artifactId> com.soluzionasf.arqw10.common </ artifactId>
<version> 1.0.0-SNAPSHOT </ version>
<packaging> eclipse-plugin </ packaging>
