Few steps for creating projects with Java 9 and Maven

Java 9 & Maven template for building JAR with dependencies inside

Simple template for Java 9 & Maven for building JAR with dependencies inside

Getting started

Example project for making plot with jFreeChart

All directory structure is generated by

	mvn -B archetype:generate \
	  -DarchetypeGroupId=org.apache.maven.archetypes \
	  -DgroupId=app \
	  -DartifactId=appId

from https://maven.apache.org/guides/getting-started/index.html tutorial

then added Plot class, compiled from StackOverflow answer https://stackoverflow.com/a/16718736

Magic with pom.xml

In pom.xml add jFreeChart

<dependencies>
  ...
  <dependency>
     <groupId>org.jfree</groupId>
     <artifactId>jfreechart</artifactId>
     <version>1.0.19</version>
  </dependency>
</dependencies>

Also insert Java 9 Maven support

<properties>
  <maven.compiler.source>1.6</maven.compiler.source>
  <maven.compiler.target>1.6</maven.compiler.target>
</properties>

Then add maven-assembly-plugin configuration compiled from answer StackOverflow answer https://stackoverflow.com/a/1729202

<build>
  <plugins>
     <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-assembly-plugin</artifactId>
        <executions>
           <execution>
              <id>bundle</id>
              <phase>package</phase>
              <goals>
                 <goal>single</goal>
              </goals>
              <configuration>
                 <descriptorRefs>
                    <descriptorRef>jar-with-dependencies</descriptorRef>
                 </descriptorRefs>
                 <archive>
                    <manifest>
                       <mainClass>app.App</mainClass>
                    </manifest>
                 </archive>
              </configuration>
           </execution>
        </executions>
     </plugin>
  </plugins>
</build>
