Caused by: java.lang.NoSuchMethodError: org.springframework.data.mongodb.core.MongoTemplate.<init>(Lcom/mongodb/Mongo;Ljava/lang/String;)V

Looks like jar is corrupted or missing, check all spring related jar are 4.x or higher versionif that doent work then:
Mongobee depends on Spring 4.x jars which may conflicts with Spring boot 2.x

try the below way

  @Bean  public Mongobee mongobee(){    Mongobee mongobee = new Mongobee("mongodb://localhost:27017/seed");    mongobee.setChangeLogsScanPackage(InitialData.class.getPackageName());            mongobee.setMongoTemplate(template);    return mongobee;  }

You need change Mongobee by Mongock if you use Springboot 2. The syntax is almost the same because the Mongock project is the continuation of the Mongobee project.

Springboot:

@Beanpublic SpringBootMongock mongock(ApplicationContext springContext, MongoClient mongoClient) {  return (SpringBootMongock) new SpringBootMongockBuilder(mongoClient, "yourDbName", "com.package.to.be.scanned.for.changesets")      .setApplicationContext(springContext)       .setLockQuickConfig()      .build();}

Spring:

@Beanpublic SpringMongock mongock() {  MongoClient mongoclient = new MongoClient(new MongoClientURI("yourDbName", yourMongoClientBuilder));  return new SpringMongockBuilder(mongoclient, "yourDbName", "com.package.to.be.scanned.for.changesets")      .setLockQuickConfig()      .build();}
