Description

Given the following example:

Bar.java

public class Main {
   public static void main(String[] args) {
      for (StackTraceElement stackTraceElement : Thread.currentThread().getStackTrace())
         System.out.println(stackTraceElement);
   }
}

and pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

   <modelVersion>4.0.0</modelVersion>
   <groupId>com.greg</groupId>
   <artifactId>TestApp</artifactId>
   <version>1</version>
   <build>
      <plugins>
         <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <configuration>
               <debug>none</debug>
               <source>1.5</source>
               <target>1.5</target>
            </configuration>
         </plugin>
      </plugins>
   </build>
</project>

after compiling and running we get:

cmd

{TestApp}\target\classes>dir Main.class
05/02/2010  XX:XX               564 Main.class

{TestApp}\target\classes>java -cp . Main
java.lang.Thread.dumpThreads(Native Method)
java.lang.Thread.getStackTrace(Thread.java:1383)
Main.main(Main.java:3)

NOTE !!!: the number of line (Main.java:3) has been shown

However when you compile the same java code using the javac we get:

cmd

{TestApp}\src\main\java>javac -g:none -source 1.5 -target 1.5 Main.java

{TestApp}\src\main\java>dir Main.class
05/02/2010  XX:XX               477 Main.class

{TestApp}\src\main\java>java -cp . Main
java.lang.Thread.dumpThreads(Native Method)
java.lang.Thread.getStackTrace(Thread.java:1383)
Main.main(Unknown Source)

NOTE !!!: the number of line has not been shown

Please find the whole sample project in Eclipse that uses m2eclipse plugin, that is configured for using external maven 2.2.1
