1189833 - Generated eclipse workspace refuses to start up

Status: RESOLVED WORKSFORME

(Firefox Build System :: General, defect)

Description

[Botond Ballo [:botond]]

After my computer experiences an unclean shutdown, Eclipse refuses to open my workspace generated using the './mach build-backend -b CppEclipse' command added in bug 973770.

When I try to open the workspace, I get an error dialog saying:

  An error has occurred. See the log file <workspace>/.metadata/.log

Said log file contains the following exception:

I haven't been able to find a workaround besides re-generating the workspace (and thus having to re-index the code from scratch).

[Botond Ballo [:botond]]

I'm now sometimes experiencing this even when my computer hasn't suffered an unclean shutdown. It's making the eclipse project generation practically unusable :(

Comment 2

[Benoit Girard (:BenWa)]

I don't really use it and I don't really hear about anyone using it but you and perhaps roc. I'm not sure it's really worth maintaining it. Perhaps I should deprecate it until more people want to use and maintain it.

Comment 3

[Jonathan Watt [:jwatt]]

Is this still happening, Botond?

Comment 4

[Botond Ballo [:botond]]

I haven't come across this recently. I'm not going to force my computer into an unclean shutdown to double-check :) Will close as WFM, and reopen if it happens again.
