Running Java program with jar file (Netbeans/Maven) - help needed

Question

My goal is to build my program and being able to execute from the cmd line. When I clean a build the app, I get the following error when i run it:

    C:\Users\Jonny\Desktop>java -cp dfareporting-cmdline-sample-1.0.0.jar com.google

I'm not a java developer but I understood that it happens because of the pom.xml configuration (well hopefully I understood ;))

Here is my POM config:

What should I do now to be able to execute the jar file from cmd line?

Thx for you help.

"Caused by: java.lang.ClassNotFoundException: com.google.api.client.json.JsonFact ory" Clealy states, you are missing this from your classpath. — SSC

After I compile, I get the followings in my target directory: checkstyle-cachefile checkstyle-checker.xml checkstyle-header.txt checkstyle-result.xml classes dfareporting-cmdline-sample-1.0.0.jar findbugsXml.xml generated-sources maven-archiver surefire So based on that, what should be the command to run it? — Rgonomike
– Rgonomike, Commented Jun 4, 2013 at 9:13
Do you see if there are libs packaged with your jar? Or if you are referencing them from your pom.xml to the right path? Because I don't think if your libs are being packaged into the jar. — SSC
– SSC, Commented Jun 4, 2013 at 9:17
To run the jar, you do : java -jar JARFILE.jar and if you don't have manifest file then java -cp JARFILE.jar package.name.CLASSNAME — SSC
– SSC, Commented Jun 4, 2013 at 9:18
None if these commands work... The classes are all in the jar package:` CreateActivityReport.class CreateCompleteReport.class CreateFloodlightReport.class CreateStandardReport.class DfaReportingSample.class DownloadReportFile.class GenerateReportFile.class GetAllReports.class GetAllUserProfiles.class GetDimensionValues.class RefreshToken.class UpdateCompleteReport.class UrlDownload.class — Rgonomike

add this to your pom.xml file:

<build> 
<plugins> 
<plugin> 
<groupId>org.apache.maven.plugins</groupId> 
<artifactId>maven-dependency-plugin</artifactId> 
<executions> 
<execution> 
<id>copy-dependencies</id> 
<phase>prepare-package</phase> 
<goals> 
<goal>copy-dependencies</goal> 
</goals> 
<configuration> 
<outputDirectory>${project.build.directory}/dependency-jars</outputDirectory> 
<overWriteReleases>false</overWriteReleases> 
<overWriteSnapshots>false</overWriteSnapshots> 
<overWriteIfNewer>true</overWriteIfNewer> 
</configuration> 
</execution> 
</executions> 
</plugin> 
<plugin> 
<groupId>org.apache.maven.plugins</groupId> 
<artifactId>maven-jar-plugin</artifactId> 
<configuration> 
<archive> 
<manifest> 
<addClasspath>true</addClasspath> 
<mainClass>FULLPACKAGENAME.CLASSNAME</mainClass> 
<classpathPrefix>dependency-jars/</classpathPrefix> 
</manifest> 
<manifestEntries> 
<Class-Path>.</Class-Path> <!-- HERE IS THE IMPORTANT BIT --> 
</manifestEntries> 
</archive> 
</configuration> 
</plugin> 
</plugins> 
</build>

Then first clean by maven and then build as Maven.

You need to add all your libraries to classpath.

For example, if all of your dependencies are in lib folder in working dir, then your command should be:

java -cp dfareporting-cmdline-sample-1.0.0.jar;./lib/* com.google.api.services.samples.dfareporting.cmdline.DfaReportingSample

UPD.

There is other solution.

You should add this plugin to your pom.xml:

<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>
          <manifestEntries>
            <Premain-Class>Your.agent.class</Premain-Class>
            <Agent-Class>Your.agent.class</Agent-Class>
            <Can-Redefine-Classes>true</Can-Redefine-Classes>
            <Can-Retransform-Classes>true</Can-Retransform-Classes>
          </manifestEntries>
        </archive>
      </configuration>
    </execution>
  </executions>
</plugin>

And then just run assembly goal from this plugin and you will get all yours code and libs in one jar.

You also can do this from command line:

> mvn org.apache.maven.plugins:maven-assembly-plugin:2.2-beta-2:assembly

Shouldn't it be different if it's a Maven project? In my code I have these import statements and the code runs fine with Netbeans import com.google.api.client.json.JsonFactory; import com.google.api.client.json.jackson2.JacksonFactory;

pbespechnyi Over a year ago

@Rgonomike, nope, you should add all libs to your classpath... But, there is another solution. It's require some changes in your pom.xml. See my update.

Thanks, Mr.777 gave me a solution. The dependencies were not downloaded. Now they are but they are not in the Jar itself, which is fine by me. I won't dig further for the moment. Thanks!
