Protocol buffers Hybris规则引擎不调用促销

当我们想要在集群环境中调用升级时，我们会得到一个异常。这看起来像是maven依赖性问题，protobuf java库版本错误。但我们找不到解决办法

类似问题：

---

在进行ant生产时，扩展的顺序是不断变化的。有两个Protobuf罐，分别用于solr和ruleengine。基于Solr的protbuf版本为2.5，规则引擎存在问题

---

可能的解决方案是将“ant生产”之后生成的localextions.xml替换为原始的localextions.xml。然后，成功启动服务器。

打得好，非常感谢！这应该作为SAP端的bug打开。两个本地扩展的行为应该相同。同一个库的多版本可能也是一个问题。
