Can not compile Nutch1.4 with ant

all I'm trying to deploy Nutch1.4 to Hadoop cluster(following this page). I got some problems when compiling Nutch with ant.

problem 1

When I run ant command, I got the following error:

/home/xenserver/apache-nutch-1.4-bin/build.xml:71: invalid Date syntax in "01/25/1971 2:00 pm"

I remove attribute "datetime" from line 71 in file build.xml and run ant again. Then I got another problem.

problem 2

The error is:

/home/xenserver/apache-nutch-1.4/build.xml:412: syntax errors in ivy file: java.text.ParseException: http://java.sun.com/xml/jaxp/properties/schemaLanguage in file:/home/xenserver/apache-nutch-1.4/ivy/ivy.xml at org.apache.ivy.plugins.parser.xml.XmlModuleDescriptorParser$Parser.parse(XmlModuleDescriptorParser.java:273)

........

What's wrong with the steps above? Is there any tutorial for compiling Nutch1.4? Need your help.Thanks in advance.

For compiling nutch 1.4, all you have to do is run ant clean deploy from the nutch directory. The output is created in the directory named 'runtime' with 2 folders: one for local mode and other one for cluster mode.

please check the date settings and ant installation on your machine. I think that is casing the issue. Also have you tampered/ edited /home/xenserver/apache-nutch-1.4/ivy/ivy.xml ? Please check that file too.

EDIT:

There is some problem with the build file when executed on your Linux box. Check these out: this and this.

These are the things that you should verify on your setup:

  1. java version and ant version : dont use old ones. get the latest ones or ones that are compatible with your nutch release. FYI: for nutch-1.4 I am using apache-ant-1.8.3 and java jdk1.6.0_18. This combination works perfectly fine with me.
  2. Check that you have installed a JDK and not a JRE
  3. Check if your JAVA_HOME environment variable point to the JDK. System PATH variable must have $JAVA_HOME/bin and $ANT_HOME/bin appended to it. ANT_HOME variable must point to the ant installation directory.
  4. Can you successfully run normal ant targets on any other build files ? try out with small ant build file.

  5. Still facing the same issue, run ant command with -v option. This will provide more information about the error faced. eg.

    ant -v clean deploy
