问题
I am trying to add dependency of GitHub to my eclipse IDE but the market place shows the following error if I search using 'git' keyword.
MarketplaceDiscoveryStrategy failed with an error Cannot complete request to http://marketplace.eclipse.org/api/p/search/apachesolr_search/git?client=org.eclipse.epp.mpc.core&client.version=1.7.7.v20190521-1752&os=linux&ws=gtk&nl=en_IN&java.version=12.0.2&product=org.eclipse.sdk.ide&product.version=4.11.0.I20190307-0500&runtime.version=3.15.200.v20190301-1641&platform.version=4.11.0.v20190307-0500: HTTP Server 'Internal Error': http://marketplace.eclipse.org/api/p/search/apachesolr_search/git?client=org.eclipse.epp.mpc.core&client.version=1.7.7.v20190521-1752&os=linux&ws=gtk&nl=en_IN&java.version=12.0.2&product=org.eclipse.sdk.ide&product.version=4.11.0.I20190307-0500&runtime.version=3.15.200.v20190301-1641&platform.version=4.11.0.v20190307-0500 HTTP Server 'Internal Error': http://marketplace.eclipse.org/api/p/search/apachesolr_search/git?client=org.eclipse.epp.mpc.core&client.version=1.7.7.v20190521-1752&os=linux&ws=gtk&nl=en_IN&java.version=12.0.2&product=org.eclipse.sdk.ide&product.version=4.11.0.I20190307-0500&runtime.version=3.15.200.v20190301-1641&platform.version=4.11.0.v20190307-0500 HttpComponents connection error response code 500.

I ran in this issue myself this morning.
This seems to be a Problem with the Marketplace itself. If you use the search functionality on https://marketplace.eclipse.org you'll get a Search is temporarily unavailable. If the problem persists, please contact the site administrator. Message.
Hopefully this might be a temporary Problem. This Bug has also been reported already: https://bugs.eclipse.org/bugs/buglist.cgi?quicksearch=MarketplaceDiscoveryStrategy%20failed%20with%20an%20error.
My solution has to directly install the desired software from the Update-URL I found using google and the "Help"/"Install new Software" Menuitem.
