BUILD FAIL: IO error scanning directory

[Henry Saginor]

Hi all

I get the following error when building jetspeed 1.4:

BUILD FAILED: file:jetspeed-1.4/build/build.xml:592: IO error scanning directory 
jetspeed-1.4\lib

When I looked at build.xml I found this at line 592

<java classname="org.exolab.castor.builder.SourceGenerator" fork="yes">
        <classpath refid="classpath"/>
        <arg value="-i" />
        <arg value="${src.xml.dir}/jetspeed-portal-content.xsd" />
        <arg value="-f" />
        <arg value="-dest" />
        <arg value="${src.java.dir}" />
        <arg value="-package" />
        <arg value="org.apache.jetspeed.xml.api.jcm" />
</java>

I looked everywhere and can't find any resolution to this problem.
Can anyone help? Please ...
