对于某些捆绑包，command-bundle元素和ext:property-placeholder
所以看起来Karaf核心包有无效的蓝图xml？这是一个错误吗？
答案 0 :(得分：1)
Apache Karaf 2.x和3.x版本在内部使用蓝图。 蓝图规范有些限制，并未涵盖通过命名空间的任何扩展机制。 Aries Blueprint和Gemini Blueprint都支持这种方式，但方式不同。 那些Karaf版本依赖于Aries Blueprint，因此让Gemini Blueprint工作有点困难。
Karaf 4.x不再在内部使用Blueprint，因此在那里安装Gemini Blueprint要容易得多。
也就是说，双子座蓝图并不活跃，所以你应该看看Aries Blueprint的实现。如果需要，Aries Blueprint还提供完整的Spring兼容层。
