assembly plugin - Executable Jar veya Zip Dosyası Oluşturur, Fat Jar İçin Kullanmayın

Giriş

Not : Bu plugin'i fat jar üretmek için kullanmamak lazım. shade plugin bu iş için daha iyi

Açıklaması şöyle

The Assembly Plugin for Maven enables developers to combine project output into a single distributable archive that also contains dependencies, modules, site documentation, and other files.

Açıklaması şöyle

The Assembly plugin relies on a specific assembly.xml configuration file. It allows you to pick and choose which files will be included in the artifact. Note that the final artifact doesn't need to be a JAR: the configuration file lets you choose between available formats e.g. zip, war, etc.

The plugin manages common use-cases by providing pre-defined assemblies. The distribution of self-contained JARs is among them.

Fat Jar

Örnek

Şöyle yaparız

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-assembly-plugin</artifactId>
  <version>3.1.1</version>
  <configuration>
    <descriptorRefs>
      <descriptorRef>jar-with-dependencies</descriptorRef>
    </descriptorRefs>
  </configuration>
  <executions>
    <execution>
       <id>assemble-all</id>
       <phase>package</phase>
       <goals>
         <goal>single</goal>
       </goals>
     </execution>
   </executions>
 </plugin>

Executable Jar

Spring projeleri için çalışmaz!. Aslında Fat Jar ile Executable Jar aynı şey. Aradaki tek fark birisinde mainClass belirtilmesi.

Örnek

Şöyle yaparız. Burada mainClass ve execution goal belirtiliyor.

<plugin>
  <artifactid>maven-assembly-plugin</artifactid>
  <configuration>
    <descriptorRefs>
      <descriptorRef>jar-with-dependencies</descriptorRef> <!--1-->
    </descriptorRefs>
    <archive>
      <manifest>
        <mainClass>com.foo.executable.jar.ExecutableJarApplication</mainClass> <!--2-->
      </manifest>
    </archive>
  </configuration>
  <executions>
    <execution>
      <goals>
        <goal>single</goal> <!--3-->
      </goals>
      <phase>package</phase> <!--4-->
    </execution>
  </executions>
</plugin>

Açıklaması şöyle. Burada tek gıcık nokta çıktı olarak verilen jar ismi foo-1.0-SNAPSHOT-jar-with-dependencies.jar şeklinde.

1. Reference the pre-defined self-contained JAR configuration

2. Set the main class to execute

3. Execute the single goal

4. Bind the goal to the package phase i.e. after the original JAR has been built

Running mvn package yields two artifacts:

<name>-<version>.jar

<name>-<version>-with-dependencies.jar

The first JAR has the same content as the one that would have been created without the plugin. The second is the self-contained JAR. You can execute it like this:

java -jar target/executable-jar

Örnek

Şöyle yaparız

<plugin>
  <artifactId>maven-assembly-plugin</artifactId>
  <configuration>
    <archive>
      <manifest>
        <mainClass>fully.qualified.MainClass</mainClass>
      </manifest>
    </archive>
    <descriptorRefs>
      descriptorRef>jar-with-dependencies</descriptorRef>
    </descriptorRefs>
  </configuration>
</plugin>

Burada execution goal vermediğimiz için şöyle kullanırız

mvn clean compile assembly:single

Çalıştırmak için şöyle yaparız

java -cp target/s2-app-1.0-SNAPSHOT-jar-with-dependencies.jar

Örnek

Şöyle yaparız.

<plugin>
  <artifactId>maven-assembly-plugin</artifactId>
  <configuration>
    <archive>
      <manifest>
        <mainClass>YOUR MAIN CLASS HERE</mainClass>
      </manifest>
    </archive>
    <descriptorRefs>
      <descriptorRef>jar-with-dependencies</descriptorRef>
    </descriptorRefs>
  </configuration>
  <executions>
    <execution>
      <id>make-assembly</id>
      <phase>package</phase>
      <goals>
        <goal>single</goal>
      </goals>
    </execution>
  </executions>
</plugin>
