如何使用antrun插件将类作为jar文件通过Maven运行

Question

I have the following plugin configuration in my maven pom.xml

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-antrun-plugin</artifactId>
    <version>1.7</version>
    <executions>
        <execution>
        <id>prepare-database</id>
        <phase>pre-integration-test</phase>
        <configuration>
            <target name="run">
                <java fork="false"  failonerror="yes" classname="Test">
                    <arg line="arg1 arg2"/>
                </java>
            </target>
        </configuration>
        <goals>
            <goal>run</goal>
        </goals>
        </execution>
    </executions>
</plugin>

The class is located in a package under src/main/java the package is called com.ab and the class file is called Test.java

package com.a.b;

public class Test {
    public static void main(String[] args)
      {
        String arg1 = args[0];
        String arg2 = args[1];
        doStuff(arg1, arg2);
      }

    public static void doStuff(String arg1, String arg2)
      {
          System.out.println(arg1);
      }
}

When trying to execute the maven build that runs the ant task I get the following error:

An Ant BuildException has occured: Could not find Test. Make sure you have it in your classpath

I understand that the file can not be found but I have no clue what to do about it. Any help would be highly appreciated.

Take a look at the standard-directory-layout article on the Maven site.

Source folder should be src/main/java (and not src/java/main)

Also, what exactly do you want to do with this ant target ? Do you simply need the fork ? Why can't you run it as a pure unit test, or a maven integration test and forget about the ANT target ?

H2 is well-suited for running in-memory. It only takes a couple of lines to connect to the DB and start testing, all inside the JVM, all using standard jUnit code.

 Class.forName("org.h2.Driver"); 
 Connection con = DriverManager.getConnection("jdbc:h2:mem:mytest", "sa", ""); 
 Statement sst = con.createStatement(); 
 sst.executeUpdate(SQL);
