我正在使用 google BETA API：AutoML Natural Language，在训练 API 之后，我在 Java SE 项目中进行了测试，获得了令人满意的结果，但是，当我将其迁移到 Java EE 项目时，我遇到了不同的问题。关于：
-Java -版本： 1.8.0_201
-Payara 版本：5.191
-google-cloud-automl 依赖：0.97.0-beta
当我尝试运行实体提取服务（PredictionServiceClient 类）时，它返回错误java.lang.NoSuchMethodError: com.google.common.base.Preconditions.checkArgument (ZLjava / lang / String; CLjava / lang / Object;) V，根据不同的来源，此错误是由不同版本的番石榴库之间的冲突引起的。我认为我的特定错误是因为番石榴在 payara 中的版本是 19.0.0 而 google-cloud-automl 需要版本> 20。
要解决此错误，payara 建议在此处修改文件 glassfish-application.xml，“这样，EAR 的 lib / 目录中包含的库将优先”，但这对我不起作用。
代码是在本文档的帮助下编写的

还有另一种方法可以做到这一点吗？我的应用程序真的不可能在 pom 中使用番石榴版本而不是 payara 服务器吗？在 maven mvn 依赖中测试命令行之后；tree -Dverbose在我的项目路径中我没有收到任何依赖项错误。那么番石榴真的可以成为这个错误的原因吗？我觉得我已经尝试了一切，但我找不到解决我问题的可能方法，提前谢谢你。
