After deploying a Spoofax plugin into a new Eclipse instance there some of the live update features are broken (tested with the example Entity project):

1. The generated files are not added to the project. You need to manually refresh the project workspace to discover the new files.

2. The live update feature of Spoofax does not seem to work. When opening the source and generated file side-by-side the project, the generated file is not automatically updated as in the development version. You have to transfer the focus the generated file editor to for Eclipse detect the change. Additionally eclipse popup an dialog asking of the content should be loaded from disk or not.

While saving and regenerating the file the following error/warning is emitted:

ERROR: SSL/mkdir: Cannot create directory /Users/sven/Documents/workspace/Test/src/

MyEditor: rewriting failed, trace:

Manually enabling the following options solve the issues:

General -> Workspace -> Refresh using native hooks or polling
General -> Workspace -> Refresh on access

I think this may be a combination of a few problems. Having to manually enable those options (which are definitely disabled by default) is strange. Could you give detailed steps to reproduce this?

Thanks.

1. Create an Entity example project.
2. Export the plugin into a local update site (as described in the Spoofax tour).
3. Start a clean (straight from the webpage) Eclipse instance.
4. Import the example plugin from the local update site (restart eclipse).
5. Create a new project.
6. Create a new file matching the file extension of the Entity plugin.
   • add content to the file
   • save file

Without the changes of the settings Eclipse will not see the newly generated files. Once the workspace has been refreshed Eclipse will see the generated files. When opening the generated file side-by-side the update of the generated files is not reflected in the editor window (without the changes).

NOTE: The shown error message occurs regardless of the update settings have been enabled or not.

What Spoofax version is this on? Unstable?

The refresh problems are moved to a separate issue https://yellowgrass.org/issue/Spoofax/619. Please comment there.

I use the unstable branch.

I could not reproduce this on the unstable or nightly branch. I don’t get any index-compile-ast errors. Any more missing info?

Not sure what to tell you. I attached the plugin jar to the issue. Below is the listing of the created update site.

Maybe the index got corrupted somehow? You could try closing Eclipse, remove the .cache directory on the project that gives the error and open Eclipse again. There’s a few bugs in unstable that could cause this, but will be fixed in the upcoming 1.1 release.

I can confirm that removing the .cache directory removed the issue.

Great :)
