How to provide dependent library locations (jar files) in the ant build file?

[ishtiaque hussain]

Hi, 

I am trying to run Randoop on downloaded projects from SourceForge.

I wrote an ant build file to automate the process.

But its failing with 'NoClassDefFoundError'. 

For example:

WARNING: classForName(com.imsmart.main.MMergeTIFF) yielded exception: com/sun/media/jai/codec/SeekableStream

 java.lang.NoClassDefFoundError: com/sun/media/jai/codec/SeekableStream

at java.lang.Class.forName0(Native Method)

  at java.lang.Class.forName(Class.java:169)

....

....

I think it's because the project has dependencies on other libraries which it cannot find.

In the above case, the class 'com.imsmart.main.MMergeTIFF' has dependency on a jar file.

How do I add the directory that has all the jar files in the classpath?

I'd really appreciate if anyone could please me on this.

Thanks,

The ANT build file I use is as below: Please note, 'MyListOfClasses.txt' has all the list of classes, and the *.class files are under '\imsmart' folder.

-------------------------------------------------------------------------------------------------

<?xml version="1.0" encoding="UTF-8"?>

<project name="RUGRAT build file" default="randoop">

<!-- target: randoop -->

<target name="randoop" >

<java classname="randoop.main.Main" fork = "yes">

<classpath>

<pathelement location="..\..\..\..\..\..\..\RUGRAT-Bipul machine\Rugrat Experiments\Tools\Randoop\randoop.1.3.2.jar"/>

<pathelement path="..\..\imsmart"/>

</classpath>

<jvmarg value="-Xmx30720m"/>

<jvmarg value="-XX:PermSize=1024m"/>

<jvmarg value="-XX:MaxPermSize=1024m"/>

<arg value="gentests" />

<arg value="--classlist=MyListOfClasses.txt" />

<arg value="--output-tests=fail"/>

<arg value="--junit-output-dir=randoop-fail-min"/>

</java>

</target>

</project>

The first example in the Randoop manual, at
http://randoop.googlecode.com/hg/doc/index.html#running_randoop
shows use of the classpath argument to Randoop. This is different than
the classpath argument to the underlying JVM.

When trying to debug an Ant script, two useful tips are:
* First, run your command from the command line to ensure that it works.
* Then, run your Ant buildfile with the -d (debug) flag to ensure that
the command it runs is exactly the one that you ran from the command line.

Good luck!

I replied to the previous email already, so you know how to proceed to diagnose the problem and produce a more useful report.

(In short, reproduce it from the command line; the Randoop developers want to help you, but they don't have time to debug your Ant scripts.)
