we updated eclipse version to 4.13 and gradle version 3.x . while creating project in our application , we are getting org.eclipse.buildship.core.internal.GradlePluginsRuntimeException: Can’t read root project location for project located at —(workspace)-----
!MESSAGE SynchronizingBuildScriptUpdateListener failed
anybody having idea regarding this ?

I'm assuming you used an older Buildship version before. I remember we changed the project properties stored in the `${projectDir}/.settings/org.eclipse.buildship.core.prefs` files and new Buildship version complains about missing entries. You can fix this problem by using the `Import Gradle project` wizard to reimport your project into the Eclipse workspace.  I'd even delete the `.prefs` file, just to be sure you have clean preferences stored.

Buildship complains that the `D:\runtime-com.spacetimeinsight.sistudio.product2\tttt\.settings\org.eclipse.buildship.core.prefs` does not exist. How did you create it? With the following steps it should work:
- delete D:\runtime-com.spacetimeinsight.sistudio.product2\tttt from the disk
- define `tttt` in your settings file
- create a the tttt diretory
- Right-click on the root project then select  Gradle > Refresh Gradle Project
After the sync finishes the new project should appear in the workspace.

What we are doing is , we are setting target platform for our product with the above configurations. while creating our new component/project at runtime, we are adding gradle nature automatically. The exception is coming at runtime, while creating project in my product/Application. 
D:\runtime-com.spacetimeinsight.sistudio.product2\tttt   
this tttt  is created at runtime . It is created in my product but in the console that buildship exception is coming. My observations is that the gradle is not adding to the created one.
we are not doing here anything manually to delete . so anyother workaround for this
