Migrating Spring boot 1.5 to 2.x unable to start app

Question

I'm new to Spring boot and trying to migrate an existing application from 1.5 to 2.0. I went through the migration guide and found out that including the preoperties-migrator as dependency in my parent pom will point out the changes to be done in order to migrate.Hence i added the below dependency in my pom.xml

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-properties-migrator</artifactId>
    <version>2.0.4.RELEASE</version>
</dependency>

Once i added the below dependency, app startup failed with below error.

"message":"Application startup failed","logger_name":"org.springframework.boot.SpringApplication","thread_name":"main","level":"ERROR","level_value":40000,"stack_trace":"java.lang.NoClassDefFoundError: org/springframework/boot/env/OriginTrackedMapPropertySource\n\tat org.springframework.boot.context.properties.migrator.PropertiesMigrationListener.onApplicationPreparedEvent(PropertiesMigrationListener.java:67)\n\tat org.springframework.boot.context.properties.migrator.PropertiesMigrationListener.onApplicationEvent(PropertiesMigrationListener.java:57)\n\tat org.springframework.boot.context.properties.migrator.PropertiesMigrationListener.onApplicationEvent(PropertiesMigrationListener.java:44)\n\tat org.springframework.context.event.SimpleApplicationEventMulticaster.doInvokeListener(SimpleApplicationEventMulticaster.java:172)\n\tat org.springframework.context.event.SimpleApplicationEventMulticaster.invokeListener(SimpleApplicationEventMulticaster.java:165)\n\tat org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent(SimpleApplicationEventMulticaster.java:139)\n\tat org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent(SimpleApplicationEventMulticaster.java:122)\n\tat org.springframework.boot.context.event.EventPublishingRunListener.contextLoaded(EventPublishingRunListener.java:91)\n\tat org.springframework.boot.SpringApplicationRunListeners.contextLoaded(SpringApplicationRunListeners.java:66)\n\tat org.springframework.boot.SpringApplication.prepareContext(SpringApplication.java:356)\n\tat org.springframework.boot.SpringApplication.run(SpringApplication.java:301)\n\tat org.springframework.boot.SpringApplication.run(SpringApplication.java:1118)\n\tat org.springframework.boot.SpringApplication.run(SpringApplication.java:1107)\n\tat com.move.aws.eai.inventory.common.app.BaseApplication.run(BaseApplication.java:140)\n\tat com.move.aws.eai.inventory.bulk.Application.main(Application.java:10)\nCaused by: java.lang.ClassNotFoundException: org.springframework.boot.env.OriginTrackedMapPropertySource\n\tat java.net.URLClassLoader.findClass(URLClassLoader.java:381)\n\tat java.lang.ClassLoader.loadClass(ClassLoader.java:424)\n\tat sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:349)\n\tat java.lang.ClassLoader.loadClass(ClassLoader.java:357)\n\t... 15 common frames omitted\n"}

Answer 1

It was a silly error.

I changed the parent pom.xml to use the latest Spring boot version.
