Overview

The Exec plugin allows you to execute Java classes and other scripts.

Running in the Same VM

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>exec-maven-plugin</artifactId>
    <configuration>
        <mainClass>org.novaordis.util.xb.XBrowser</mainClass>
        <commandlineArgs>-verbose true</commandlineArgs>
    </configuration>
</plugin>

Command Line:

mvn exec:java 

Running in DEBUG Mode

export MAVEN_OPTS="-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=5005"
<pre>

=Running a Main Class Located in One of the Test Packages=

By default, the classpath used by the Exec plugin does not include test classes. If the class you want to execute is located in one of the test packages, the classpath scope must be extended as follows:

<pre>
<plugin>
    ...
    <artifactId>exec-maven-plugin</artifactId>
    <configuration>
        ...
        <classpathScope>test</classpathScope>
        ...
    </configuration>
</plugin>

Then, run the plug in as follows:

mvn -e clean test-compile exec:java

Allowing More Memory for the Heap

export MAVEN_OPTS="-Xmx1024m"
