Solved - unrecognized project; missing plug-in

 After I cloned a web service project, I got a "unrecognized project; missing plug-in" message when I was trying to open it in NetBeans.

I fixed it by installing the Java EE base plug-in by following the steps below.

1. Click the Tools in the top menu of Apache NetBeans IDE and select Plugins.

2. Select the Available Plugins tab in the pop-up Plugins window.

3. Right click on the Java EE base plug-in and install it.

Before you install the Java EE base plug-in, check the nbproject/project.xml file to confirm that the type is <type>org.netbeans.modules.web.project</type>
