plugins - Downloading Eclipse plug-in update sites for offline installation

Question

A plug-in that I want to install provides an update site for installation. However, the Eclipse installation that I want to install it to is on a machine that is not connected to the Internet. Is there a way for me to access the site (HTTP, FTP, etc.) to download the files in it for offline installation?

Answer 1

Eclipse offers a way of mirroring these sites automatically, either through the command line or through ant tasks.

Mirror based on p2 information

$eclipse_home/eclipse -application org.eclipse.equinox.p2.artifact.repository.mirrorApplication -source $1 -destination $2
$eclipse_home/eclipse -application org.eclipse.equinox.p2.metadata.repository.mirrorApplication -source $1 -destination $2

Reference: Equinox p2 repository mirroring

Mirror based on site.xml information

java -jar $eclipse_home/plugins/org.eclipse.equinox.launcher_*.jar -application org.eclipse.update.core.standaloneUpdate -command mirror -from $from -to $to

Reference: Running the update manager from the command line
