Binary package hint: ant

ant 1.7.0-3 on Ubuntu 8.04

When I try to build the attached project which has an AntStructure task, I get the following error (ant -v):

I have ant-optional installed and can still see the problem.

Can you reproduce the problem with the attached build.xml? It is a very small file.

try to download apache net package from http://dev.xiaonei.com/apache-mirror/commons/net/binaries/commons-net-1.4.1.tar.gz

Unpack it and place the jar file into your ant CLASSPATH, then try again.

Good luck.

Yes that works, thanks.

I also installed the libcommons-net-java package and changed the ant command line to this:

ant -lib /usr/share/java/commons-net.jar dtd

And that also works.

Not an ant error. Missing build dependency caused the failure. Please feel free to reopen if you disagree.

Why is it that it's not necessary to put e.g. the JUnit jar in -lib, but it is necessary to put commons-net? They are both optional dependencies.

The <dtd> task loads all of ant's tasks and the only one which fails is <ftp>, which needs commons-net in the classpath.

Seems like a packaging problem to me. Perhaps there needs to be a symlink in /usr/share/ant/lib.

Rodney,

Please don't assign bugs to me. If I am going to work on something I will assign it to myself.

I will try to take a look at this issue but it may not happen immediately.
