maven - camunda-bpm-spring-boot-starter-webapp dependency not working and embedded tomcat failing -

i trying create simple camunda spring boot starter webapp based on examples given here https://github.com/osteinhauer/camunda-spring-boot-starter-examples . main application class has simple piece of code :

@springbootapplication public class startapp {      public static void main(string[] args) {         // todo auto-generated method stub springapplication.run(startapp.class, args);     }  } 

my pom.xml looks below :

<project xmlns="http://maven.apache.org/pom/4.0.0" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xsi:schemalocation="http://maven.apache.org/pom/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">   <modelversion>4.0.0</modelversion>   <parent>     <groupid>info.quarrymen.camunda-spring-boot-starter-examples</groupid>     <artifactid>parent</artifactid>     <version>0.0.1-snapshot</version>   </parent>   <artifactid>quick-start-webapp</artifactid>    <dependencies>   <dependency>   <groupid>org.camunda.bpm.extension.springboot</groupid>   <artifactid>camunda-bpm-spring-boot-starter</artifactid>   <version>2.3.0-snapshot</version> </dependency>     <dependency>       <groupid>org.camunda.bpm.extension.springboot</groupid>       <artifactid>camunda-bpm-spring-boot-starter-webapp</artifactid>       <version>${camunda-bpm-spring-boot-starter.version}</version>     </dependency>   </dependencies> </project> 

but embedded tomcat fails start below error :

looks adding camunda-bpm-spring-boot-starter-webapp won't . additional configuration required . tried many combinations of maven dependencies , didn't work out . has faced similar issue , please or let know correct set of dependencies can run camunda webapp on localhost spring boot . in advance .

@daniel ,after trying pom.xml , getting below errors . different previous errors :

just set property camunda-bpm-spring-boot-starter.version on pom.xml file this.

 <properties>     <camunda-bpm-spring-boot-starter.version>2.1.2</camunda-bpm-spring-boot-starter.version> </properties> 

and \import camunda dependencies again through maven, , try start app again.

this output spring boot when camunda started
