Install plug-in myeclipse8.0

Install plug-in myeclipse8.0
First case: the plug-in is stored in a folder.
After decompression, you can directly put it in the dropins directory under myeclipse8.0, and then delete the org. Eclipse. Update directory in the configuration directory of myeclipse. Will myeclipse automatically load this plug-in?
Case 2: The plug-in file contains the features and plugins folders (the following uses installing the svn plug-in as an example)
Step 1
After I download site-1.6.5.zip, decompress it and put it in my, drive D:/myplugins Directory, which forms D:/myplugins/Features/; D:/myplugins/plugins; D: /myplugins/site. XML.
Step 2
I created a file SVN. Link in the genuitec/myeclipse 8.x latest/dropins/directory.
Path = D: // myplugins
An error occurs when you restart myeclipse. The plug-in cannot be installed successfully.
However, when I delete the three artifacts. XML, content. XML, and site. xml files in the D:/myplugins folder.
Restart myeclipse.
