Mac snow leopard and subclipse [message #484294]

I had been using Eclipse 3.4.1 with subclipse 1.4.1 just
fine on a Leopard Mac.

On a Snow Leopard machine I installed Eclipse 3.5 Cocoa
32-bit and my copied workspace looked OK. Then I installed
subclipse.tigris.org/update_1.6.x. Appeared to install OK.

Wasn't sure what to do next. Looked in Perspectives and
found <SVN Library Exploring> but it is all gray. Eclipse
Preferences does not show anything about SVN, just CVS. Can
someone suggest a next step?

I was not able to get a 32 bit Eclipse to run on Snow Leopard even after
changing Java preferences to put the 32 bit version first in priority.
Eventually loaded the 64 bit Cocoa and subclipse works fine, as do the swt
portions. The error message was something to the effect of unable to load
32 bit swt components in a 64 bit JVM. Not sure if this is the problem you
are having.

On a Snow Leopard machine I installed Eclipse 3.5 Cocoa
64-bit "Classic" and my copied 3.4.1 workspace looked OK.
Then I used the "EPP Update Site" at
http://download.eclipse.org/technology/epp/packages/galileo/
to install all the JEE components. That looked OK. Then I
used subclipse.tigris.org/update_1.4.x to install all but
the Mylyn integration. I was back in business.

Many thanks to all the developers who made this work!
Eric Rizzo's instructions at
http://bewarethepenguin.blogspot.com/2009/07/screencast-crea t
ing-eclipse-download.html
were a key ingredient.

(Two things I have not tried: Subclipse 1.6.x and Mylyn
integration with subclipse. Superstition on my part.. my
environment is working without them.)

I haven't tried Snow Leopard yet, but my understanding is that it removes
Java 1.5 and switches the default JVM to Java 1.6 (64-bit, presumably). So
if I'm correct about that, you'll need to either install a Java 1.5 VM, and
make sure that your eclipse.ini points to it, or else change to a Cocoa
64-bit build.

Snow Leopard provides 32 and 64 bit Java 1.6. Both 32 and
64-bit Cocoa Eclipse seemed to work. 64-bit Eclipse works
with Subclipse 1.4.x so far. Snow Leopard seems faster
overall.

Sometimes running Eclipse with the -debug command line option can help
troubleshoot problems with plug-ins not loading.

While there is a 32 bit Java 1.6 in Snow Leopard, the default JVM for
Eclipse remains the 64 bit JVM even if you use the Java preferences utility
in OSX and put the 32 bit JVM above the 64 bit JVM. I think you can
indicate a 32 bit JVM with a command argument when you invoke Eclipse
(-d32???) but I solved the problem by getting the 64 bit Cocoa eclipse
classic distribution and then adding the needed other functions (RCP, etc.).
