尽管有 category.xml，但 Tycho 构建失败并显示“没有为 p2 存储库指定内容”

Question

Eclipse 插件Markdown-Editor 不使用 Maven/Tycho 构建。构建失败并显示消息

[ERROR] Failed to execute goal org.eclipse.tycho:tycho-p2-repository-plugin:0.18.1:assemble-repository (default-assemble-repository)
 on project markdown.editor.site: No content specified for p2 repository -> [Help 1]

类似的配置StartExplorer plugin工作正常：

category.xml：

<?xml version="1.0" encoding="UTF-8"?>
<site>
   <feature url="features/markdown.editor.feature_1.0.0.jar" id="markdown.editor.feature" version="1.0.0">
      <category name="markdowneditor"/>
   </feature>
   <category-def name="markdowneditor" label="Markdown Editor">
      <description>
         Extend the text editor to provide good Markdown support.
      </description>
   </category-def>
</site>

pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"

与tycho-p2-repository-plugin fails with "No content specified for p2 repository"相关
和How to correctly specify eclipse-plugins in category.xml of tycho eclipse-repository?

Answer 1

如果版本是用-SNAPSHOT``, then incategory.xmlversion should have.qualifier`定义的

<feature url="features/markdown.editor.feature_1.0.0.jar" id="markdown.editor.feature" version="1.0.0.qualifier">
