Batman @ Work

Have you ever wondered exactly what the classpath is you’re using when compiling your java classes using the ant task “javac”? Well, here’s a useful little addition that can easily be added to your ant builds. It’s really no rocket science, but just provides a “visual” listing of the contents of the classpath.

<target depends="_setup" name="_compile" />
      <pathconvert property="echo.path.compile" pathsep="${line.separator}| |--" refid="project.class.path"></pathconvert>

      <echo message="|-- compile classpath" />
      <echo message="| |" />
      <echo message="| |-- ${echo.path.compile}" />

      <javac debug="${compile.debug}" srcdir="src" target="1.5" destdir="build" source="1.5">
             <classpath refid="project.class.path" />
      </javac>
</target>

Output similar to the following can be expected:

init:
compile:
|-- compile classpath
|   |
|   |-- /home/bruce/projects/quartz/lib/activation.jar
|   |-- /home/bruce/projects/quartz/lib/log4j.jar
|   |-- /home/bruce/projects/quartz/lib/mail.jar
|   |-- /home/bruce/projects/quartz/lib/commons-cli-1.1.jar
|   |-- /home/bruce/projects/quartz/lib/commons-configuration-1.5.jar
|   |-- /home/bruce/projects/quartz/lib/commons-dbutils-1.1.jar
|   |-- /home/bruce/projects/quartz/lib/commons-dbcp-1.2.2.jar
|   |-- /home/bruce/projects/quartz/lib/commons-pool-1.3.jar
|   |-- /home/bruce/projects/quartz/lib/commons-io-1.3.2.jar
|   |-- /home/bruce/projects/quartz/lib/commons-lang-2.3.jar
