ReadWorkspaceLocations: Setting wtpDefaultServer value as default value if othercondition fails

Setting wtpDefaultServer as defaultdeployserverid and defaultdeployservername in workspaceConfiguration, if no runtime servers is found in .metadata of current workspace.
(i.e no runtime is found in .metadata/.plugins/org.eclipse.core.runtime/.settings/org.eclipse.wst.server.core.prefs of workspace)
File Name: src\main\java\org\apache\maven\plugin\eclipse\reader\ ReadWorkspaceLocations.java
Modified Method: detectWTPDefaultServer
Modified code:
if ( servers == null || servers.isEmpty() )
{
// added code
// if servers not found, then this is first time we are calling eclipse:eclipse to generate artifacts
// set wtpDefaultServer as defaultdeployserverid and defaultdeployservername
if ( wtpDefaultServer != null )

{ workspaceConfiguration.setDefaultDeployServerId(wtpDefaultServer); workspaceConfiguration.setDefaultDeployServerName(wtpDefaultServer); }

return;
}

Why this code: As per my understanding, earlier code was searching in workspace for servers runtime information in .metadata/.plugins/org.eclipse.core.runtime/.settings/org.eclipse.wst.server.core.prefs file. Otherwise it was setting above two values null. Hence generated facet file for EAR, runtime information was never getting set while generating artifacts.
