Tool for downloading eclipse plugins from update sites

Question

I need to install an eclipse plugin to a machine not connected to the Internet and I cannot find a dist to use for a local install.

Is there a tool for downloading a plugin from an update site and create a local installation archive (or a local update site)? Rumors says you can do this with eclipse, but I cant find any info on how to do it.

Not clear what the maven-2 connection is here. Is there some background information you've left out, or should this be tagged "eclipse"? – Phraseogram

Messed up the tags, sorry for that. – Nianiabi

It seems @PeterŠtibraný 's answer below does not work, at least in some cases and with Eclipse Kepler. Could you check whether this still works for you? – Radbun

Answer 1

You can use P2 mirror tool (or P2 mirror in Galileo documentation) to mirror remote metadata and artifacts repository.

Here is sample command to mirror Galileo artifacts repository locally:

eclipse\eclipsec.exe -nosplash -verbose 
-application org.eclipse.equinox.p2.metadata.repository.mirrorApplication
-source http://download.eclipse.org/releases/galileo
-destination file:d:/temp/galileo/

eclipse\eclipsec.exe -nosplash -verbose
-application org.eclipse.equinox.p2.artifact.repository.mirrorApplication
-source http://download.eclipse.org/releases/galileo
-destination file:d:/temp/galileo/

(First command mirrors metadata, second mirrors artifacts. Command should be on one line in windows)

After you run these commands, you can use file:d:/temp/galileo as a local mirror.

Alternatively, you can use P2 Mirror Ant Task, which lets you specify installable units (plugins or features) to mirror. Note: when specifying feature, don't forget to use .feature.group suffix)

To be honest, I am still not sure how it works exactly: whether to mirror only artifacts and let P2 Publisher generate metadata, or whether to mirror both artifacts and metadata. Please share your findings when you succeed. Thank you. – Godliman

Updated answer: when I run both commands (mirror metadata, mirror repository), I got correct update site for local use. I tested with download.eclipse.org/tools/mylyn/update/weekly/e3.4 – Godliman

I used the mirror artifact command and used the downloaded files locally and it worked like a charm. Have not trided the ant task (yet). Thanks Peter for your help. – Nianiabi

I tried doing this, and got to the point where Eclipse asks me to approve the license, but after that, it tries to go after the original files at the on-line repository - so, this doesn't work as is! @PeterŠtibraný, please help... – Radbun

@einpoklum: I'm sorry, I can't help you, I don't use Eclipse anymore. Try asking new question here on SO with more details, maybe somebody can help. – Godliman

Now there is also a support for p2 sites mirroring in maven using tycho plugins: http://wiki.eclipse.org/Tycho/Additional_Tools

One of the advantage is that you can very precisely specify what installable unites you want to mirror, for which os/ws/arch, ...

For instance to mirror Eclipse Indigo you can use following pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"

You might find Building a custom Eclipse package helpful, although it's probably a bit more heavyweight that what you need.
