我在Eclipse中有一个项目，它是一个WebService项目REST API，并且我还在Configure Build path -> Add Project中添加了另一个项目，并且在我的API方法中添加了另一个项目，我正在调用TestNGCreator该类如下。
该项目基本上在Java中使用jersey框架创建REST API，当我调用任何垂直方法时，即执行它将调用另一个项目，该类位于另一个项目中，我在该项目的Build路径中添加了项目，而我的其他方法运行正常但是当我从其他项目调用方法时，出现此错误。
我需要在POM.xml中声明我正在使用此类和此方法的位置吗？
我需要通过调用TestNGCreator.main(null);来运行自动化
我的另一个项目是java TestNGCreator类中的自动化项目，它位于自动化项目中。通过调用此方法，我需要在上述类上调用，并且在执行此操作时会出错。
错误：

我在您的pom文件中看不到test-ng依赖性。 请添加以下内容并尝试。
<dependency>
