maven to package app jar, create project classpath, goals

Question

Update : solved by using assembly plugin to copy in artifacts, to a folder or create a redistributable zip file. Do not know maven. Used STS/ eclipse to make a maven project that is a swing standalone application. App runs fine inside STS. Example helped. {figured out how it's getting the runner script. template is there in the source. maven just filters it and puts the current jar name. Now just need to figure out how to stop maving putting my app jar in the assembly lib (want it one level up so can click it and start, and 80 other jars are in lib), using ant for that now }

Original question Cannot find the lib folder. Apparently the app refers to local jars in the maven local repo.

Can I tell maven to copy them to some folder under my project like dist/lib and make a full app jar in my dist/ (I do not care if dist is some other directory name -> if there is a maven default do not mind that). I want a distributable set of jars to ship.

When I build my project now it puts classes in the

./target/classes

directory ./ is my project folder here

Did as Andreas suggested Added shade to pom :-

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>
            <version>2.1</version>
            <configuration>
                <!-- put your configurations here -->
                <transformers>
            <transformer implementation="org.apache.maven.plugins.shade.resource.DontIncludeResourceTransformer">
                <resource>.txt</resource>
                <resource>resources/</resource>
            </transformer>
          </transformers>

            </configuration>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>shade</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

From IDE build :

Dont see anything

From command line if I give

mvn package  shade:shade

Used assembly (suggested by John Ament) as described here maven-assembly-example/releases or zip

Got a big tar and zip with all the jars. Most of the work done. Now just need to unpack, make a script so I have

 project-home
   -> dist
   -->   MyApp.jar
   --> lib
   --->  other1.jar
   --->  other2.jar
   --> conf
   --->  myResources1.jpg
   --->  otherFiles2.xyz

Answer 1

Create a shaded jar (UberJar) by adding this to your plugins section:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
    <version>2.1</version>
    <configuration>
      <!-- put your configurations here -->
    </configuration>
    <executions>
      <execution>
        <phase>package</phase>
        <goals>
          <goal>shade</goal>
        </goals>
      </execution>
    </executions>
  </plugin>

Maven will create on jar that contains all classes from your sources and all of your dependencies.

Answer 2

While shade is a good solution, you may not want those dependencies in your JAR. You can also use the assembly plugin to copy in artifacts, to a folder or create a redistributable zip file.
