Can I download some files from http while maven lifecycle? any plugin?
Seems like wagon-maven-plugin from CodeHaus allows to download files over HTTP (though this is not is original goal).
Here is an example downloading GlassFish zip before integration tests:
org.codehaus.mojo
wagon-maven-plugin
1.0
download-glassfish
pre-integration-test
download-single
http://download.java.net
glassfish/3.1/release/glassfish-3.1.zip
${project.build.directory}/glassfish
