----------------------------------------
At the moment, it seems like JDT-LS totally ignores possible extensions from existing JDT extension point. It would be quite valuable to honor those in order to provide richer edition experience.

[JBoss JIRA] (JBIDE-25896) Reduce footprint for Headless usage with JDT-LS
by Mickael Istria (JIRA)
Mickael Istria created JBIDE-25896:

Summary: Reduce footprint for Headless usage with JDT-LS
Key: JBIDE-25896
URL: https://issues.jboss.org/browse/JBIDE-25896
Project: Tools (JBoss Tools)
Issue Type: Sub-task
Components: build
Reporter: Mickael Istria
JBoss Tools extensions for JDT-LS do consume a lot of disk space. While splitting the bundles into UI/non-UI for usage with JDT-LS, we should evaluate other useless dependencies to get rid of in order to lighten the resulting LS.

[JBoss JIRA] (JBIDE-25895) Make Jax-RS features work headless for integration with JDT-LS
by Mickael Istria (JIRA)

Summary: Make Jax-RS features work headless for integration with JDT-LS
Key: JBIDE-25895
URL: https://issues.jboss.org/browse/JBIDE-25895
Project: Tools (JBoss Tools)
Issue Type: Sub-task
Components: webservices
Reporter: Mickael Istria
JDT-LS can be extended for Java edition. Jax-RS, which contributes completion providers, error markers and hovers should provide those in a headless bundle which doesn't depend on UI to be able to contribute to JDT-LS.
Wizards and other pure UI should be in a dedicated .ui bundle.

I couldn't see Jax-RS contributing completion or warning because the Jax-RS plugin requires UI Harness to startup, and UI Harness is not available in JDT-LS. So for Jax-RS, it would require to first split the bundle into a UI and a non-UI part.
I tried to get CDI reporting something, but I didn't manage to get CDI error markers even from JBoss Tools... So if anyone has an example project showing CDI warnings, please share it so I can test. [~fbricon] maybe?

[JBoss JIRA] (JBIDE-25858) Minishift binary is not set up after CDK runtime download
by Rob Stryker (JIRA)
[ https://issues.jboss.org/browse/JBIDE-25858?page=com.atlassian.jira.plugi... ]
Rob Stryker commented on JBIDE-25858:
-------------------------------------
The reason this doesn't seem to work is a simple and dumb coding error. It is not the case that minishift home is the base of runtime detection. This was changed on March 20th. See this commit: https://github.com/jbosstools/jbosstools-openshift/pull/1697/files#diff-b...
However... this error was due to poor logic, unfortunately. PR to come shortly.
> Minishift binary is not set up after CDK runtime download

> Key: JBIDE-25858
> URL: https://issues.jboss.org/browse/JBIDE-25858
> Project: Tools (JBoss Tools)
> Issue Type: Bug
> Components: runtime-detection
> Affects Versions: 4.5.3.AM3
> Reporter: Martin Malina
> Assignee: Rob Stryker
>
> This is a followup of JBIDE-25835 .
> Recently a new feature was added - cdk can be downloaded directly from the IDE now.
> As with other runtimes, there are two main paths you can take:
> a) New Server -> Download
> b) Preferences -> Runtime Detection -> Download
> tl;dr: b) doesn't work properly with cdk because minishift binary is still not set after the download.
> There is quite a big difference between a) and b). With a), you are adding a server manually and once your download is finished, the correct path is predefined for you. Runtime detection is not involved.
> With b), the server is downloaded, extracted and then the path is added to runtime detection which is in turn run. This will result in the new server being detected and added.
> Now cdk should theoretically support both of these paths. a) works - you're in the middle of adding a cdk server manually, you invoke the download and once that's done, the minishift binary field is filled properly for you.
> But b) doesn't work properly for cdk, because runtime detection for cdk is built around your minishift home and not the minishift binary path. (I don't really know why that's the case, but I guess you had a good reason for it.) So when you do b), cdk binary is downloaded, but what's added to runtime detection is ~/.minishift (or $MINISHIFT_HOME if set). The result is that the cdk server adapter is added once the download is finished, but the minishift binary remains empty. So the usefulness of this feature is questionable.
> Maybe you will say that there is no way to fix this. I hope you will at least agree that this is not ideal and b) doesn't really work properly right now.
> I don't know what the proper solution for this is but let me start with a question: Wouldn't it make sense to change runtime detection of cdk so that it uses the minishift binary as the main path? What's stopping us from doing that?
> Sorry for the lengthy description, I felt I needed to explain the whole context here.
