Can run a Maven project within IntelliJ but not from Terminal

I have created a console application in IntelliJ that utilizes Maven. From within IntelliJ I can compile and run the app with no issues ...

From terminal however i execute the following commands (in the same dir with pom.xml)

mvn Install -U
java -classpath target/myApp-2.0-SNAPSHOT.jar MainClass

The install command seems to build the jar file without any issue. The second command gives me the following error

Exception in thread "main" java.lang.NoClassDefFoundError: org/codehaus/jackson/JsonParseException

In my pom.xml my dependencies are as follows

<dependencies>
    <dependency>
        <groupId>joda-time</groupId>
        <artifactId>joda-time</artifactId>
        <version>2.3</version>
    </dependency>
    <dependency>
        <groupId>org.codehaus.jackson</groupId>
        <artifactId>jackson-mapper-asl</artifactId>
        <version>1.5.0</version>
    </dependency>
</dependencies>

It seems to me that its not pulling in the Jackson Dependencies but im not sure what im missing here.

As said, the problem you have is that your jar needs the other jars to execute.

I see 3 solutions :

1- As stated above, when you run the program, add the -classpath argument

2- Use the maven-jar-plugin to add the dependencies in the manifest, then you'll only have to have the dependencies at the requested place to have all execute. See http://maven.apache.org/shared/maven-archiver/examples/classpath.html#aAdd

3- Package the dependencies inside your jar with a plugin like jarjar : http://sonatype.github.io/jarjar-maven-plugin/

This will create you a standalone jar

Hope it can help.

Maven has no impact on your runtime classpath (only your compile-time classpath). You need to add your dependencies to the classpath.
