MARS.1 -> MARS.2 upgrade kills installation [message #1738730]

We've been using MARS.1 for a while without troubles. Well, a few troubles, which is why today I decided to get MARS.2, figuring that it had been out for a while and any really bad bugs would be discovered already.

Unlike my previous upgrades, this time I tried the "Help -> Check for updates" inside the running Eclipse. That was a mistake.

The "check for updates" showed four or five changed components (the stuff that I presume makes up the differences between MARS.1 and MARS.2). I told it to proceed, the download was fine, and the install looked fine. Then it prompted me to restart Eclipse.

On restart, it simply displayed the attached dialog. (Incidentally, if the text in that dialog could be selected with a mouse, that would make investigating and reporting this kind of thing a lot easier.)

The log file it refers to is chock full of stack traces which mean nothing to an end user, so I've attached it here unmodified except for masking potential PII in the username.

Trying to run Eclipse directly now gives the same startup error. The previous MARS.1 installation didn't require any particular tweaking to get running, so...

I'm going to download MARS.2 and install it in a fresh directory.

It's hard to say what's the root cause, but the following sticks out as the first and repeated cause:

Unresolved requirement: Import-Package: com.ibm.icu.text

This package is provided by plug-in com.ibm.icu, so you may want to check if the corresponding jar is present and valid.

Next observation: in one case it says:

Unresolved requirement: Import-Package: com.ibm.icu.text; version="3.8.1"

I believe that Mars.2 should contain version 54.1.1 of the plug-in, so requesting version 3.8.1 seems odd, to say the least.

Unmet dependencies could indicate that you are running on too old a jvm. But seeing you are running on 1.8.0_60 should rule out that kind of problem.

Was that successful?

I have no idea what jar file that would be, or where. I don't even know what plugin that is (a human-meaningful name, I mean). The internals of Eclipse are a black box to me, I'm afraid.

It was! I have not tried its "Help -> Check for updates", but if this version stops trashing static imports on parse errors, I won't need to. Smile

Thanks again.
