我正在尝试使用 Tycho 生成分类的 p2 存储库。制作基本上有三个步骤(比较Eclipse 文档):

  1. 下载捆绑包
  2. 触发 org.eclipse.equinox.p2.publisher.FeaturesAndBundlesPublisher
  3. 触发 org.eclipse.equinox.p2.publisher.CategoryPublisher

我在 Maven pom 文件中配置。第 1 步和第 2 步运行良好,而第 3 步失败:

Status ERROR: this code=0 publishing result null children=[Status ERROR: org.eclipse.equinox.p2.updatesite code=0 Error
generating category xml action. org.eclipse.equinox.p2.core.ProvisionException: Error reading update site file:/<path>/category.xml.]

这是我的 pom.file

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

        </configuration>
      </plugin>
    </plugins>
  </build>
</project>

还有我的 category.xml

<?xml version="1.0" encoding="UTF-8"?>
  <site>
    <category-def name="all" label="Maven osgi-bundles"/>
    <iu>
      <category name="all"/>
      <query>
        <expression type="match">providedCapabilities.exists(p | p.namespace == 'osgi.bundle')</expression>
     </query>
   </iu>
</site>

如果我手动执行这些步骤,则会发生相同的错误。我错过了什么?

虽然理论上可以通过 Tycho 调用低级 p2 操作,但我不建议您尝试解决此问题。

该工件已在Maven存储库中可用,因此您可以通过pomDependencies=consider. 然后,例如,您可以使用 Tycho 的打包类型构建一个带有工件的 p2 存储库eclipse-repository

您将需要以下 POM 配置...

  ...
  <packaging>eclipse-repository</packaging>

  <dependencies>
    <dependency>
      <groupId>org.apache.cxf</groupId>
      <artifactId>cxf-bundle</artifactId>
      <version>2.7.5</version>
    </dependency>
  </dependencies>

  <build>
    <plugins>
      <plugin>
        <groupId>org.eclipse.tycho</groupId>
        <artifactId>target-platform-configuration</artifactId>
        <version>${tycho-version}</version>
        <configuration>
          <pomDependencies>consider</pomDependencies>
        </configuration>
      </plugin>
    </plugins>
  </build>

...和一个 category.xml 明确列出您要包含的捆绑包:

<?xml version="1.0" encoding="UTF-8"?>
<site>
   <bundle id="org.apache.cxf.bundle" version="0.0.0">
      <category name="all"/>
   </bundle>
   <category-def name="all" label="Maven osgi-bundles"/>
</site>
