Question

我是一名Java新手，对于Eclipse / OSGi等很新。

我正在尝试运行OSGi包。我在OSGi中安装了所有依赖的jar。但是在OSGi控制台中启动捆绑包时，我收到以下错误：

org.osgi.framework.BundleException: The bundle could not be resolved.  
Reason:Missing Constraint:Require-Bundle:org.eclipse.xtext;bundle-version="0.0.0"

标准导入未解决。我该如何解决这个问题呢？如果我发布更多信息，请告诉我。

osgi> diag 24

即使在添加了org.eclipse.osgi包之后，它也会被列为缺少依赖项。

您的捆绑包没有误导标准的java导入。 bundle清单包含Require-Bundle指令，因此只有在部署org.eclipse.xtext包后，bundle才会重新启动。由于此指令未自动添加，您必须手动添加它或者从另一个Manifest复制。

你的包真的需要xtext吗？如果是，那么您必须将extext bundle部署到OSGi环境中。如果没有，那么删除Require-Bundle标头，它应该可以工作。

无法解析标准java导入
