[Hadoop-common-user] ant version problem

Apache Ant version 1.8.0 compiled on February 1 2010

should be just fine. I think you need to have something later than 1.7.2 or so

1.8.2 will work, but when you install via a linux distro the classpath
is trickier to set up, as you need to get all dependent jars on the
classpath.

what does ant -diagnostics say?

OK, that's a linux distro install without any extra jars. There's enough
in a JVM these days that the basic operations will all work.

Looking at that class,
http://svn.apache.org/viewvc/hadoop/common/branches/branch-0.20/src/core/org/apache/hadoop/record/compiler/ant/RccTask.java?view=markup

I don't see any obvious dependencies on non-standard things,

20 import java.io.File;
21 import java.util.ArrayList;
22 import org.apache.hadoop.record.compiler.generated.Rcc;
23 import org.apache.tools.ant.BuildException;
24 import org.apache.tools.ant.DirectoryScanner;
25 import org.apache.tools.ant.Project;
26 import org.apache.tools.ant.Task;
27 import org.apache.tools.ant.types.FileSet;

The only odd one is the generated Rcc taks.

That taskdef message from ant is saying something imported is missing.

Try running ant in debug mode (ant -debug) to see if it gives a clue,
but there's very little that anyone else can do here.

Hi!

In case you're still facing this problem (unlikely but I wanted to document it
for the others), try setting ant.home in a build.properties file.

I put it in my home directory. Then run ant veryclean compile

Cheers
