Eclipse locked up when building workspace

Yesterday eclipse worked as expected. But when starting up this morning it hangs forever (at least for to long for me to wait for it) on “building workspace “.

After excluding the ususal suspects (subversive, m2eclipse, mac osx firewall) it turned out – this time- , that one project referenced an outdated builder (org.openarchitectureware.base.oawBuilder) that was removed from my system some months ago. It seems that I forgot that particular project when migrating from oaw to the eclipse modelling project.

Removing the builder manually from the .project-file enabled eclipse to build the workspace and me to hack my first lines of code this morning.

And I have absolutely no idea why it suddenly stopped working. Or the other way around: why it did work over the last months.

Migrating OAW 4.3.1 to Eclipse Galileo

We recently decided to migrate our eclipse environment as soon as possible to Galileo. This implied that we had to migrate our openarchitectureware projects as well.

We are using OAW since 2006 in many projects. Most of them are still running and we moved them periodically to current OAW releases. So the task for today was to migrate OAW 4.3.1  to the Galileo release.

The migration was not really painful, but I had to collect  hints from several sources and it took me some time, to get running workflows again.

Therefor I decided to write down once the neccessary migration steps. Kompletten Artikel lesen

Don’t rename Eclipse.app

Don’t rename Eclipse.app! At least, don’t do it on MacOS X. I did it, because I have several Eclipse versions installed and I wanted to distinguish them in the Dock. This caused Eclipse to crash on startup. But not immediately. It took some time untill the error emerged and this made it difficult for me to relate the startup failure to the renaming of the app. Kompletten Artikel lesen

Ganymede Update

Yesterday I dared to update Eclipse Ganymede to 3.4.1 (Mac OS X 10.5 – Leopard, Java 1.6) by hitting “Help -> Software Updates -> Installed Software -> Update” which was, as usual, not a good idea. Kompletten Artikel lesen
