Building the example fails when the JDT LS cannot be accessed

[kittaakos]

When the http://download.eclipse.org/jdtls/snapshots/jdt-language-server-latest.tar.gz link is not available, the Java extension build fails, hence the whole build process fails.

Eventually, the http://download.eclipse.org seems to be down.

[marcdumais-work]

I saw this error intermittently today (locally and on travis). It seems to work now.

[kittaakos]

Yes, it works now. I can confirm that. We will figure out something not to depend on eclipse.org when building the application.

[akosyakov]

I am going to push the downloaded archive for now. We will need to redownload it locally to upgrade.

[epatpol]

As we now have it downloaded locally in the git repo, can we consider this issue "fixed"?

[hexa00]

@epatpol The real solution would be to fail more gracefully but I don't see that happening until we get an extension system that enables runtime extensions.

And the examples are examples only...

So I'm closing this one for now. Reopen if it's still a problem.
