title: Spring boot application fails to start with javax.validation.BootstrapConfiguration error
body: <p>I am developing a simple spring boot web enabled application. Spring boot Version is 2.2.1. When I start application I am getting this error</p>
  
  <pre><code>***************************
  APPLICATION FAILED TO START
  ***************************
  
  Description:
  
  An attempt was made to call a method that does not exist. The attempt was made from the following location:
  
      org.hibernate.validator.internal.xml.config.ValidationBootstrapParameters.&lt;init&gt;(ValidationBootstrapParameters.java:63)
  
  The following method did not exist:
  
      javax.validation.BootstrapConfiguration.getClockProviderClassName()Ljava/lang/String;
  
  The method's class, javax.validation.BootstrapConfiguration, is available from the following locations:
  
      jar:file:/home/shantanu/.m2/repository/io/swagger/swagger-codegen-cli/2.3.0/swagger-codegen-cli-2.3.0.jar!/javax/validation/BootstrapConfiguration.class
      jar:file:/home/shantanu/.m2/repository/javax/validation/validation-api/2.0.1.Final/validation-api-2.0.1.Final.jar!/javax/validation/BootstrapConfiguration.class
      jar:file:/home/shantanu/.m2/repository/jakarta/validation/jakarta.validation-api/2.0.1/jakarta.validation-api-2.0.1.jar!/javax/validation/BootstrapConfiguration.class
  
  It was loaded from the following location:
  
      file:/home/shantanu/.m2/repository/io/swagger/swagger-codegen-cli/2.3.0/swagger-codegen-cli-2.3.0.jar
  
  
  Action:
  
  Correct the classpath of your application so that it contains a single, compatible version of javax.validation.BootstrapConfiguration

  <p>I have no idea what is causing this error. I even tried putting exclusions for javax.validations on multiple dependencies but nothing helped. Here's the POM dependency tree. Please help.</p>
