Java – add additional path to exec Maven plugin

I want to add an extra classpath for exec Maven plugin

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>exec-maven-plugin</artifactId>
  <version>1.1.1</version>
  <configuration>
    <executable>java</executable>
    <classpathScope>runtime</classpathScope>
    <arguments>
      <argument>%classpath:/Users/kornp/resources</argument>
      <argument>org.drrabbit.maventest.App</argument>
    </arguments>
  </configuration>
</plugin>

How do I configure it?

Solution

I have some configuration files in a specific directory outside the source folder So I'm for my POM The XML file defines additional resources

My example directory structure is:

+ src
+ conf
  - app.properties
  - log4j.xml
- pom.xml

My POM xml：

<build>
  <resources>
    <resource>
      <directory>conf</directory>
    </resource>
    <resource>
      <directory>src/main/resources</directory>
    </resource>
  </resources>

  <plugins>
    <plugin>
      <groupId>org.codehaus.mojo</groupId>
      <artifactId>exec-maven-plugin</artifactId>
      <version>1.2.1</version>
      <configuration>
        <executable>java</executable>
        <mainClass>com.mycompany.MyMainClass</mainClass>
      </configuration>
    </plugin>
  </plugins>
<build>

Now we can execute the program:

mvn clean compile exec:java
