Question

I want to create a jar file of a Java project, which compiles. I’ve looked on the internet but all the examples of how to do this seem to take one java file and work on that. I want to jar the root of the java project. How is this possible?

Thanks

IntelliJ

According to this Stackoverflow topic you can built jar file using

You didn’t specify your IDEA version.
Before 9.0 use Build | Build Jars, in
IDEA 9.0 use Project Structure |
Artifacts.

Maven

You should learn to use a build tool like maven. You then could use the maven assembly plugin

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

Ant

Or you could use ant(2) to create a jar file.
