使用指向本地p2存储库的tycho构建本地eclipse插件 [英] Build local eclipse plugins using tycho pointing to local p2 repository
问题描述
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在我的项目中，我创建了一个p2布局库。
I am creating some Eclipse plugin and features that require third-party plugins and features. In order to include these dependencies into my project, I created a p2 layout repository.
注意：我的p2工件不是Maven项目...但是，我使用Maven风格建筑。这是p2存储库的pom.xml
Note: My p2 artifacts are not Maven project... However, I am using Maven style building. Here is the pom.xml for the p2 repository
<properties>
<tycho-version>0.18.0</tycho-version>
</properties>
<repositories>
<repository>
<id>eclipse-platform-m6</id>
<layout>p2</layout>

上述构建成功，并创建（并验证）p2存储库。我在项目的目标/ 目录中获得以下结构
The above builds successfully, and creates (and verifies) a p2 repository. I get following structure in my target/ directory of the project
- 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构建我的插件和功能，并引用上面创建的p2存储库。我有我的插件和功能的以下项目结构
Now, I use Tycho for building my plugins and features and refer the p2 repository I created above. I have following project structure for my plugins and features
- bundle.parent
- bundle.mainplugin
- bundle.mainplugin.test.fragment
- bundle.mainplugin.feature
这是我的bundle.parent pom.xml
Here is my bundle.parent pom.xml
<repositories>
<repository>
<id>eclipse-platform-m6</id>
<layout>p2</layout>
<url>http://download.eclipse.org/eclipse/updates/3.8</url>
</repository>
<repository>
<id>third-party-eclipse-plugins</id>
<layout>p2</layout>
<url>file:///.../target/repository</url>
</repository>
</repositories>
<modules>
<module>../bundle.mainplugin</module>
<module>../bundle.mainplugin.test.fragment</module>
<module>../bundle.mainplugin.feature</module>
</modules>
<build>
<plugins>
<plugin>
<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。不幸的是，当我的插件中的类扩展插件中的一些类时， mvn-compile 抛出编译问题。 （运行时也需要这些类）。这是错误：
Finally, I run goals mvn clean install on the parent pom.xml. Unfortunately, mvn-compile throws compilation issues when classes in my plugin extend some of the classes in plugins. (The classes are also required at run-time). Here is the error:

我的问题：
从编译器错误中，我相信Tycho不知何故不将这些第三方工件提供给我的课程有一个编译错误。有没有办法确定我的插件类是否存在于Tycho类路径中？
From the compiler errors, I believe Tycho is somehow not making these third-party artifacts available to my classes for which there is a compiler error. Is there a way to determine if my plugin classes exist in the Tycho classpath?
更新
检查了我想从此位置在Trial反应堆中提供的第三方软件包的可用性
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
所有第三方软件包成功显示。
All third-party bundles showed up successfully.
推荐答案
Sebastian Zarnekow的回答给了我一个提示。
Sebastian Zarnekow's answer gave me a hint.
Error while building an xtext project with ant: Generation of the Grammar classes fails
从错误消息中可以推断，maven无法从注入创建语言模型。原因在上面的链接中解释：
As you can infer from the error message, maven fails to create language models from injection. The reason is explained in the link above:
Xtext使用平台：EMF的/ resource URI方案。
Xtext uses the platform:/resource URI scheme of EMF.
解决方案是您需要给EMFGenerator一个新的声明模型目录应该在哪里。在**。mwe2文件中，替换以下代码
The solution is you need to give EMFGenerator a new declaration of where the model directory should be. In **.mwe2 file, replace the following code
fragment = ecore.EMFGeneratorFragment auto-inject {}
与
fragment = ecore.EMFGeneratorFragment auto-inject {
javaModelDirectory = "/${projectName}/src-gen"
}
应该诀窍。
