Projects with same app name seem to not get full snippet support (Updated)

[dshimo]

Choosing a parent dir with multiple projects as the main folder seems to mess with our language server snippet suggestions. Instead, if you open each project's root folder through Add folder to Workspace..., normal behavior resumes.

My project structure has a dir named 'starters' which contain the Maven and Gradle starter apps. Each app gets recognized by the dashboard correctly. Liberty actions work.

It seems MicroProfile snippets only appear for one project. In this case, it only appears on my Gradle Java files.

Attempting to fetch rest_* snippets in Maven yield irrelevant answers, and attempting rest_* in the Gradle project gave me only rest_get.

This final screenshot is the expected snippet list for rest_*. Here, only the Maven project is open in the workspace.

Testing on Mac, it seems as if your application names are the same in the Liberty dashboard, then snippets will fail on multi-projects.

Here, both the Maven and Gradle apps were added to the workspace. Snippets fail.

In this screenshot, Maven was added after Gradle. rest_class is still not found.

And lastly, with newly generated apps with different app names, rest_class returns. Here, I even opened the parent dir 'starters'

So this only occurs when it is the same app name in more than one project? If so, that does not seem like it would be very common in the real world?

Yes, it appears the app names must be the same to hit this bug. I agree, I don't think this would be a common scenario for users. I don't think this should be a stop ship.

Receiving the following error when opening a Maven project folder:
The Language Support for Java server crashed 5 times in the last 3 minutes. The server will not be restarted.
Tried Java: Clean Java Language Server Workspace, but still error persists.

Issue opened to address this: #312

When we open a directory containing Maven and Gradle starter apps with the same app name, one of the files is recognized as a non-project file, triggering a diagnostic message like "filename.java is a non-project file, only syntax errors are reported." In this file, snippet suggestions is not provided. However, in the other file within the same directory, suggestions are available.

Alternatively, when we open each project's root folder through "Add folder to Workspace," no diagnostic appears even if the app names are the same, and snippet suggestions are provided.
Attaching the screenshot below:

when a directory containing files with different app names is opened, the non-project file diagnostic is not displayed and we do get snippets suggestion

Based on my understanding, the issue seems to be that Visual Studio Code treats all Java projects within the same workspace as a single project, causing interference between them. Despite attempting various solutions such as:
cleaning the Java language server workspace, adding folders to the Java source path, and renaming packages, setting sourcePaths in the the settings.json file to src, still the problem persists.

Through my investigation, it appears that the only effective way to avoid the warning and receive snippet suggestions is to individually open each project's root folder by using the "Add folder to Workspace" option. By doing so, we do not receive diagnostics, and we receive snippet suggestions.

@anusreelakshmi934 Can you show the steps to go from a broken project to a working one using the "Add folder to Workspace" option? What does the project/workspace structure look like before and after? Can both projects be added to the same Workspace? And then can both projects be open in VS Code at the same time if they are part of the same Workspace?

On a separate note, what do you mean by "we do not receive diagnostics"?

[anusreelakshmi934]

When using the "Add folder to Workspace" feature, snippet suggestions become available when opening two projects with the same app name. Here's how it works:

1. First, open one of the project and then open a file in the project to check for snippet suggestions.
2. Next, go to File -> Add folder to Workspace, and select the other project with the same app name.
3. Now, check for snippet suggestions again, and you will receive them.

Now the workspace is UNTITLED (WORKSPACE). Even after saving the workspace, suggestions continue to be available. Both projects can be added to the same workspace and opened.

Regarding diagnostics, when I mentioned "We do not receive diagnostics," I meant that the diagnostic message "filename.java is a non-project file, only syntax errors are reported" is not displayed when adding projects using the "Add folder to Workspace" feature.

I'm currently facing difficulties with the workaround; I'm not receiving suggestions as expected. Additionally, I occasionally encounter a "unit is null" error when trying to open a Java file after adding the project using "Add folder to Workspace". This pertains to Issue #326 on GitHub for further context.

Also I am encountering #312 while trying to start the language server after few attempts.

[anusreelakshmi934]

Still the workaround doesnt seem to be working. May need to further investigate some other ways for the issue.
