I get these errors when I'm trying follow last step, mvn install (mvn clean works fine). Here is output after mvn clean install

regarding the warning

[WARNING] 'dependencies.dependency.(groupId:artifactId:type:classifier)' must be unique: javax.servlet:servlet-api:jar -> version 2.4 vs 2.5 @ line 77, column 17

You probably have a transient dependency that requires javax.servlet:servlet-api:2.5, but you have defined javax.servlet:servlet-api:2.4

You can either switch from javax.servlet:servlet-api:2.4 to javax.servlet:servlet-api:2.5 or add another exclusion for the javax.servlet:servlet-api:2.5 dependency. Use mvn dependency:list to find out which dependency provides the transient dependency.

Then there's another warning

[WARNING] 'build.plugins.plugin.version' for org.apache.maven.plugins:maven-war-plugin is missing. @ com.acme:acme-webapp:[unknown-version], /Users/staz/blossomproj/acme/acme-webapp/pom.xml, line 35, column 15

add [...]

...
    <build>
      <pluginManagement>
        <plugins>
          <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-war-plugin</artifactId>
