Maven - Generate Jar and War

Question

I have a CXF WS project that I would use it in another project, I would consume this WS in a Web Project but I don't know how to generate Jar file.

Please have you any idea or an example?

Thank you

Answer 1

The maven-war-plugin supports creating a separate artifact that just contains the classes.

http://maven.apache.org/plugins/maven-war-plugin/war-mojo.html

See the 'attachClasses' parameter. No need to add in the jar plugin or mess with the packaging. Just add the war plugin to pluginManagement and turn this on.

However, I fear this this isn't what you want. To consume a CXF web service, you need a client. To get a client, follow the instructions in the CXF samples for how to generate and use client stubs. You'll want a separate maven project for this.

Try adding this into your build section:

<build>
  <plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-jar-plugin</artifactId>
      <executions>
        <execution>
          <id>make-a-jar</id>
          <phase>compile</phase>
          <goals>
            <goal>jar</goal>
          </goals>
        </execution>
      </executions>
    </plugin>
  </plugins>
</build>

Add following to pom.xml of war project.

<attachClasses>true</attachClasses> to configuration of war plugin

<groupId>com.yourorg.foobar</groupId>
<artifactId>hello-world</artifactId>
<packaging>war</packaging>
<version>1.0</version>
<name>hello</name>

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-war-plugin</artifactId>
            <version>3.0.0</version>
            <configuration>
                <attachClasses>true</attachClasses>
            </configuration>
        </plugin>
    </plugins>
</build>

Add following to pom.xml of the project where you want to import jar of war project

<classifier>classes</classifier> to dependency import

<dependency>
    <groupId>com.yourorg.foobar</groupId>
    <artifactId>hello-world</artifactId>
    <version>1.0</version>
    <classifier>classes</classifier>
</dependency>

Answer 4

This is a one way to achieve it, via property. By default it will generate a war file, and when you want the jar just set the property.

mvn install -Dp.type=jar

pom.xml

<properties>
   <p.type>war</p.type>
</properties>
<packaging>${p.type}</packaging>

Answer 5

This should work:

<!-- Maven JAR plugin -->
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <executions>
        <execution>
            <id>jar-services-provided</id>
            <phase>compile</phase>
            <goals>
                <goal>jar</goal>
            </goals>
        </execution>
    </executions>
</plugin>

<!-- Install the jar locally -->
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-install-plugin</artifactId>
    <executions>
        <execution>
            <phase>install</phase>
            <goals>
                <goal>install-file</goal>
            </goals>
            <configuration>
                <packaging>jar</packaging>
                <artifactId>${project.artifactId}</artifactId>
                <groupId>${project.groupId}</groupId>
                <version>${project.version}</version>
                <file>
                    ${project.build.directory}/${project.artifactId}-${project.version}.jar
                </file>
            </configuration>
        </execution>
    </executions>
</plugin>

Answer 6

mvn package unless your project's packaging is something besides jar . Then you'd need to add an execution of the jar plugin , as described on the plugin's usage page and as the first answer showed. Better yet, if it's not a jar, divide it into two modules: one that's a jar containing your reusable code, and the other the thing that uses it.

Answer 7

The best way to achieve this is by using Maven assembly plugin by this you can also control the final name of the jar :

Add the following plugin in your pom.xml :

     <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-assembly-plugin</artifactId>
            <version>2.4</version>
            <configuration>
                <descriptors>
                    <descriptor>assembly.xml</descriptor>
                </descriptors>
                <finalName>${artifactId}-${version}</finalName>
                <appendAssemblyId>false</appendAssemblyId>
            </configuration>
        </plugin>

assembly.xml :

<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0" 
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.0 http://maven.apache.org/xsd/assembly-1.1.0.xsd">
  <id>model</id>
  <formats>
    <format>jar</format>
  </formats>
  <includeBaseDirectory>false</includeBaseDirectory>
  <fileSets>
    <fileSet>
      <directory>${project.build.outputDirectory}</directory>
      <outputDirectory>/</outputDirectory>
      <includes>
        <include>**/*</include>
      </includes>
    </fileSet>
  </fileSets>
</assembly>

You can finally build the project with the command below:

mvn clean package assembly:single install

Considering your maven project packaging to war

<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>

    <groupId>com.sample</groupId>
    <artifactId>sample</artifactId>
    <version>1.0-SNAPSHOT</version>
    <packaging>war</packaging>

add the following executions to maven-install-plugin

    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-install-plugin</artifactId>
        <version>2.5.2</version>
        <executions>
            <execution>
                <phase>package</phase>
                <configuration>
                    <packaging>jar</packaging>
                    <file>${project.build.directory}\${artifactId}-${version}.jar</file>
                </configuration>
                <goals>
                    <goal>install-file</goal>
                </goals>
            </execution>
        </executions>
    </plugin>
