Subject [jira] Created: (HADOOP-2537) make build process compatible with Ant 1.7.0
Date Mon, 07 Jan 2008 16:34:34 GMT
make build process compatible with Ant 1.7.0

                 Key: HADOOP-2537
                 URL: https://issues.apache.org/jira/browse/HADOOP-2537
             Project: Hadoop
          Issue Type: Bug
          Components: build
    Affects Versions: 0.14.4
            Reporter: Nigel Daley
             Fix For: 0.16.0

This section of build.xml behaves differently between Ant 1.6.5 and Ant 1.7.0:

    <touch datetime="01/25/1971 2:00 pm">
      <fileset dir="${conf.dir}" includes="**/*.template"/>
      <fileset dir="${contrib.dir}" includes="**/*.template"/>

In Ant 1.6.5, if the fileset is empty (which it is if you're building from a released tar.gz
distribution) then this section silently passes.

In Ant 1.7.0, if the fileset is empty, the following error is raised and the build stops:
/home/ndaley/Downloads/hadoop-0.15.1/build.xml:151: Specify at least one source--a file or
resource collection.
