This is apparently a pretty common issue, so I thought I’d write up the solution to it. When using the suggested method of installing Subversive – one of two standard SVN client plugins for Eclipse, the other being Subclipse – the installation may fail (as it did for me). The Eclipse error messages for the failure aren’t incredibly informative, but I managed to figure out the issue, so here it is:

At the time of posting, the most up-to-date versions of the Subversive plugin available for automatic or direct download from the Eclipse Marketplace site per the instructions on the plugin site are not the most current, and will not work with the automatic downloads from the Polarion source for the SVN connectors.

This is the root of the issue: Eclipse downloads the most up-to-date version of each from the specified source, and the Connectors repository has more recent versions than the Subversive repository. Since the newest Connectors have the latest Subversive build as dependencies, automatic installation fails. There are two options for a solution:

1. Download most up-to-date versions of both. You can get the most current Connectors from the Marketplace or Install New Software menus, or directly from their site. Then download the Subversive plugin for Juno. Install the latter first.
2. Download older version of the connectors after installing the older version of the plugin either through INS or Market. Just check the date of release for the plugin and make sure the Connectors release date matches.

I recommend the first option, as you’ll get the most up to date software (which is particularly useful if you want to integrate with SVN 1.7; I don’t believe the older connectors support it). The installation process should be pretty straightforward, and you shouldn’t actually need the manual connector installation once you get the Juno version of Subversive running; the automatic connector finder will get and install the new connectors just fine. On the off chance that it doesn’t, though, you’ll have the files and you can install them manually.

The process for manual installation is simple: open the “Install New Software” menu, click to Add a New Source, and choose either Local or Archive (depending on whether you’ve extracted the files you downloaded or not). Once that’s selected, you should be able to install the files just fine – including source if you want, and so forth.

Hopefully this saves someone else the headaches I went through last week while getting this configured!

Note that in the week since I wrote this draft, the Connectors have gotten even further out of date. At the time of publication, the most current set of Connectors publicly available are a full release newer than the Subversive set. I haven’t had a chance to test that, so I have no idea what if any effect this has on the dependency issues I highlighted above.
