问题描述
我正在使用OpenJDK 11.0.5 Java版本和couchbase Java客户端版本2.6.0。通过主类调用时它可以工作，但是当我通过我的api时，它会抛出NoClassDefFoundError。完整的堆栈跟踪如下：
我只是从另一个jar调用一个方法，没有任何修改。广口瓶单独工作良好。我对照master分支检查了代码，但没有任何变化。
我尝试将Couchbase客户端版本升级到最新的3.x.x，但没有成功。谁能建议我所缺少的吗？

解决方法
解决了。问题是由于长沙发Java客户端的多个版本引起的。主应用程序有一个版本，而jar有另一个版本。使所有Java客户端版本保持一致，并且可以正常工作。我使用2.6.0作为Java客户端版本。
