缺少使用 Maven Tycho 构建的更新站点的插件和功能文件夹

如何解决缺少使用 Maven Tycho 构建的更新站点的插件和功能文件夹

我正在用 Tycho 构建一个 Eclipse 插件。我想为它创建一个更新站点我有以下组件:

  • 父(pom)
  • 插件(eclipse-plugin)
  • 功能(eclipse-feature)
  • 更新站点(eclipse-repository)

但是当我在更新站点项目的目标文件夹中运行 mvn clean package 时:

├── lorem-ipsum-eclipse-update-1.0.1-SNAPSHOT.zip
├── local-artifacts.properties
├── p2agent
│   ├── org.eclipse.equinox.p2.core
│   │   └── cache
│   │       └── artifacts.xml
│   └── org.eclipse.equinox.p2.engine
│       └── profileRegistry
├── p2artifacts.xml
├── p2content.xml
├── repository
│   ├── artifacts.jar
│   ├── artifacts.xml.xz
│   ├── content.jar
│   ├── content.xml.xz
│   └── p2.index
└── targetPlatformRepository
    └── content.xml

如您所见,plugin 中缺少 featuretarget/repository 文件夹。 这是我的父 pom:

<?xml version="1.0" encoding="UTF-8"?>

    <modelVersion>4.0.0</modelVersion>

            <!--Enable the replacement of the SNAPSHOT version in the final product configuration-->

                    <execution>

                            <finalName>${project.artifactId}_${unqualifiedVersion}.${buildQualifier}</finalName>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

</project>

我做错了什么?

提前致谢。

更新:这里要求更新站点的 category.xml。

<?xml version="1.0" encoding="UTF-8"?>
<site>
   <feature id="com.lorem.ipsum.eclipse.feature" version="0.0.0">
      <category name="com.lorem.ipsum.eclipse.category"/>
   </feature>
   <category-def name="com.lorem.ipsum.eclipse.category" label="Lorem Ipsum">
      <description>
         Contains features for Lorem Ipsum plugin
      </description>
   </category-def>
</site>

顺便说一下,我的文件命名为 site.xml 因为如果我命名为 category.xml 我在尝试运行任何 maven 目标时都会出现此错误

$ mvn clean
...

我按照使用旧版本 tycho (0.18.0) 的 Eclipse 4 Plug-in Development by Example Beginners Guide by Dr Alex Blewitt 一书的说明进行操作,我使用的是 2.2.0。也许在这个版本中他们修复了将站点重命名为类别的事实,因为在同一本书中他们提到这是一个毫无意义的更改。 我引用:

将 site.xml 文件重命名为 category.xml 。 (这是一个完全 p2 需要无意义的更改,因为文件在 格式。)

解决方法

根据错误消息 (... lorem-ipsum-eclipse-update ... Missing requirement: ... com.lorem.ipsum.eclipse.feature.feature.group ...),更新站点 category.xml 引用了缺失的功能。

确保在以下两个文件中使用相同的功能 ID (<feature id="..."):

  • <your-feature>/feature.xml
  • <your-update-site>/category.xml

另请参阅 vogella 教程 Eclipse Tycho for building Eclipse Plug-ins and RCP applications:在 category.xml 中,feature 通过 ID com.vogella.tycho.feature 引用。

com.vogella.tycho.feature
