Ant installation cannot find maven-artifact-ant-2.0.4-dep.jar

Question

I'm trying to install Ant on Windows 7 using these instructions, but at stage 5, when I run the command ant -f fetch.xml -Ddest=system, I get the following error:

Buildfile: C:\Program Files\WinAnt\fetch.xml
pick-dest:

I understand that the URL is not reachable, so I tried to enter this URL into my browser, and indeed it does not exist. I found the file maven-artifact-ant-2.0.4-dep.jar at:

http://mirrors.ibiblio.org/pub/mirrors/maven2/org/apache/maven/maven-artifact-ant/2.0.4/maven-artifact-ant-2.0.4-dep.jar

instead. So how can I fix this problem?

Answer 1

Just need to update the m2.url property in the lib/library.properties file to http://mirrors.ibiblio.org/pub/mirrors/maven2.

Answer 2

Run ANT as follows

$ ant -f $ANT_HOME/fetch.xml -Ddest=user -Dm2.url=http://repo1.maven.org/maven2 

The m2.url property needs to be overloaded. The following property file in ANT needs to be updated:

$ANT_HOME/lib/libraries.properties

Using a now deprecated Maven Central URL

Answer 3

The URL is correct, but you're trying to download the files into a subfolder of Program Files (C:\Program Files\WinAnt\lib). To do so you need to be running your commands with Administrator rights.

So right click on your Command Prompt shortcut and select "run as administrator" or enter "cmd" into the search field of the start menu and press CTRL + SHIFT + ENTER.

Then try to run the ant command again:

ant -f fetch.xml -Ddest=system

And if you have trouble downloading any other files using the script, it seems to work well to just download them using your browser, put them in the right place, and then edit fetch.xml to not download the file.
