dozer with maven | 易学教程

问题

I wanted to download the latest release of Dozer mapper from github, but I didn't find any jar.

There is pom.xml file and I try to compile with command mvn package. I also added every dependencies to pom.xml file. It created dozer-5.5.0-SNAPSHOT.jar.

Next I imported this jar to my project, but it throws me java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory.

I also tried to create POM project in the netbeans and build with dependencies. After import to my project, it throws me the same exception.

I don't have any experiences with maven. How can I get correct JAR file?

回答1:

Guess your dozer-package has a dependency to slf4j, right?

Then you should checkout this Maven-Plugin: Maven-Assembly-Plugin

This will put your required dependencies into the jar.

Here you can read, how to use it

<plugins>
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-assembly-plugin</artifactId>
    version>2.4</version>
    <configuration>
      <descriptorRefs>
        <descriptorRef>jar-with-dependencies</descriptorRef>
      </descriptorRefs>
      <archive>
        <manifest>
        <mainClass>your.main.class</mainClass>
        </manifest>
      </archive>
    </configuration>
    <executions>
      <execution>
       <phase>package</phase>
         <goals>
        <goal>single</goal>
         </goals>
      </execution>
    </executions>
  </plugin>
</plugins>

If you want always execute the assemby-plugin when you invoke mvn clean package add this to your maven-assembly-plugin:

 <executions>
      <execution>
        <id>make-assembly</id> <!-- this is used for inheritance merges -->
        <phase>package</phase> <!-- bind to the packaging phase -->
        <goals>
          <goal>single</goal>
        </goals>
      </execution>
 </executions>

You have a correct jar. Simple add commons-beanutils lang and slf4j to you project with dozer or add this libraries as a maven dependencies.

回答3:

Jars required for Dozer dependency.

回答4:

Make the entry in pom.xml file.Make sure the required Jars are present.

  <dependency>
        <groupId>net.sf.dozer</groupId>
        <artifactId>dozer</artifactId>
        <version>5.3.1</version>
    </dependency>
      <properties>
<osgi.version>4.3.0</osgi.version>
