Hi,

I am using ANT with Eclipse 3.3.1.1 with Tomcat.

I am getting following error when I am trying to run a FTP target:

Could not create type ftp due to java.lang.NoClassDefFoundError: org/apache/commons/net/ftp/FTPClientConfig

Here is my FTP target:

<target name="ftp">
<ftp server="ftp.test.com" remotedir="/test" userid="user" password="password" depends="no">
<fileset dir="${meta.home}">
<include name="**/context.xml" />
</fileset>
</ftp>
</target>

Please reply if you know why it's happening.

I have also added ant 1.7 lib to my classpath, that did not help either.

Thanks,

Ankur

1. Where did you put Jakarta's Common Net library ?
2. Your target does not seem to use a classpath. How did you define the classpath, and is the above library in it ?

I had the same error message, but only in Eclipse (version 3.3).

I did not get the error on command line. I had setup up ANT_HOME variable correctly and copied the jakarta-oro-2.0.8.jar and commons-net-1.4.1.jar to %ANT_HOME%\lib

However it seems that the ANT Eclipse module does not automatically parse the %ANT_HOME%\lib directory for new jars and I had to add them manually

(preferences->Ant->Runtime, Classpath tab, Ant Home Entries -> Add External JARs...)

Then it worked.
