  This build file downloads the Maven2 Ant tasks,
28
  and installs them in the location specified by the m2.dest.dir property.

  You may need to set proxy settings. On Java1.5, Ant tries to get
31
  this from the OS, unless you use the -noproxy option.
32

    
33
  Proxies can be configured manually setting the JVM proxy values in the
34
  ANT_OPTS environment variable.
35

    
36
  For example, to set the proxy up in the tcsh shell, the command would be
37
  something like:
38

    
39
  For csh/tcsh:
40
    setenv ANT_OPTS "-Dhttp.proxyHost=proxy -Dhttp.proxyPort=8080"
41
  For bash:
42
    export ANT_OPTS="-Dhttp.proxyHost=proxy -Dhttp.proxyPort=8080"
43
  For Windows, set the environment variable in the appropriate dialog box
44
  and open a new console. or, by hand
45
    set ANT_OPTS = -Dhttp.proxyHost=proxy -Dhttp.proxyPort=8080
