using maven-war-plugin with Spring BOM

Question

I'm trying to add Spring BOM to my project. My POM is below.

1. Am I not doing something correctly here?

2. Also, a semi-related question: why do the version numbers for spring-ws, spring-data-jpa, and others not line up with the version of spring core, context, etc?

   <build>
       <finalName>myproject</finalName>
       <plugins>
           <plugin>
               <version>3.1</version>
               <artifactId>maven-compiler-plugin</artifactId>
               <configuration>
                   <source>1.7</source>
                   <target>1.7</target>
               </configuration>
           </plugin>
       </plugins>
   </build>
   
   <dependencyManagement>
       <dependencies>
           <dependency>
               <groupId>org.springframework</groupId>
               <artifactId>spring-framework-bom</artifactId>
               <version>4.0.3.RELEASE</version>
               <type>pom</type>
               <scope>import</scope>
           </dependency>
           <dependency>
               <groupId>org.springframework</groupId>
               <artifactId>spring-core</artifactId>
               <exclusions>
                   <exclusion>
                       <groupId>commons-logging</groupId>
                       <artifactId>commons-logging</artifactId>
                   </exclusion>
               </exclusions>
           </dependency>
           <dependency>
               <groupId>org.springframework</groupId>
               <artifactId>spring-context</artifactId>
           </dependency>
       ...
       </dependencies>
   </dependencyManagement>
   
   <dependencies>
   
       <!-- Spring -->
       <dependency>
           <groupId>org.springframework.ws</groupId>
           <artifactId>spring-ws-core</artifactId>
           <version>${spring-ws.version}</version>
       </dependency>
       <dependency>
           <groupId>org.springframework.data</groupId>
           <artifactId>spring-data-jpa</artifactId>
           <version>${spring-data-jpa.version}</version>
       </dependency>
   ...
   </dependencies>
   

It produces the following error:

Answer 1

The non-BOM Spring dependencies go in the dependencies section, not dependencyManagement.

<dependencies>

    <!-- Spring -->
    <dependency>
        <groupId>org.springframework.ws</groupId>
        <artifactId>spring-ws-core</artifactId>
        <version>${spring-ws.version}</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-jpa</artifactId>
        <version>${spring-data-jpa.version}</version>
    </dependency>
   <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-core</artifactId>
        <exclusions>
            <exclusion>
                <groupId>commons-logging</groupId>
                <artifactId>commons-logging</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
