I'm compiling and running some source code I got from a project called Structr (https://github.com/structr/structr). I'm able to run the program correctly with a maven mvn command but not using the JVM java command.
The compilation step goes well with maven clean install -DskipTests
On running the front-end (in the structr-ui directory), it goes well if using maven exec:exec but fails on java -cp target/lib/*;target/structr-ui-0.8.2.jar org.structr.Ui. I have some stack trace indicating java.lang.NoClassDefFoundError on org.structr.core.entity.AbstractNode and org.structr.core.EntityContext. What I find strange about this is that the maven pom.xml file in the exec entry we have
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.2.1</version>

<argument>-classpath</argument>
<argument>target/lib/*;target/structr-ui-0.8.2.jar</argument>
<argument>org.structr.Ui</argument>
</arguments>
</configuration>
</plugin>
The entire pom.xml reads

The mvn exec:exec statement looks equivalent to the java JVM statement. This question may be basically; What is maven doing differently than java, that in the maven case making the program run correctly?
Edit - additional maven and java debugging information
On mvn -X exec:exec, The output is given here http://roberthoff.com/files/mvn_exec_trace.txt
And on java -server -Dfile.encoding=utf-8 -XX:+UseNUMA -Xms1g -Xmx1g -classpath target/lib/*
;target/structr-ui-0.8.2.jar org.structr.Ui we have http://roberthoff.com/files/java_trace.txt

You have a valid question here, because according to the Maven documentation on the exec:exec goal you would need to have the <\classpath> stanza in your configuration in order to include the entire project module classpath.
However, it appears as though Maven is running the program with the fully (and properly) configured classpath for some reason.
In order to get to the bottom of the problem, I'd run Maven with the -X command line argument and carefully scan through the debug output until I found the exact command it runs. Then I'd try running it from the same directory, ensuring I am using the same Java installation and see if it works.
