This build file downloads the Maven2 Ant tasks, |
|
|
|
and installs them in the location specified by the dest.dir property. |
|
|
|
|
|
|
|
You may need to set proxy settings. On Java1.5, Ant tries to get |
|
|
|
this from the OS, unless you use the -noproxy option. |
|
|
|
|
|
|
|
Proxies can be configured manually setting the JVM proxy values in the |
|
|
|
ANT_OPTS environment variable. |
|
|
|
|
|
|
|
For example, to set the proxy up in the tcsh shell, the command would be |
|
|
|
something like: |
|
|
|
|
|
|
|
For csh/tcsh: |
|
|
|
setenv ANT_OPTS "-Dhttp.proxyHost=proxy -Dhttp.proxyPort=8080" |
|
|
|
For bash: |
|
|
|
export ANT_OPTS="-Dhttp.proxyHost=proxy -Dhttp.proxyPort=8080" |
|
|
|
For Windows, set the environment variable in the appropriate dialog box |
|
|
|
and open a new console. or, by hand |
|
|
|
set ANT_OPTS = -Dhttp.proxyHost=proxy -Dhttp.proxyPort=8080 |
