We have the same error, and considered reinstalling WindRiver, but the problem came back after a few runs. We managed to fix it (for now because I'm not sure if this solution works all the time)

For those who do have this problem and don't want to reinstall WindRiver, you could make a new workspace on WindRiver and import the code back, but into the new workspace. We have tried this, but this only seems to be temporary.

The second thing we did though, is delete the metadata folder. First, close WindRiver (not a good idea to have WindRiver running when you're deleting this folder). This file should be in the workspace folder created when you create the workspace in WindRiver. Once that file is deleted, reopen WindRiver. Note that your projects won't be there anymore (b/c you deleted metadata). Just re-import the code and build, and it should be fine.

Strangely enough, I thought this would work the same way as deleting metadata files when modding Minecraft. Turns out it did.
