方法三:直接解压
      下载SVN插件：site-1.6.10.zip
      解压后将其全部文件拷贝至：D:\Program Files\Genuitec\MyEclipse 8.5\dropins（MyEclipse的安装目录）
      重启MyEclipse即可出现SVN！

方法四：肯定可行的方法

1、下载最新的SVN包：
      http://subclipse.tigris.org/servlets/ProjectDocumentList?folderID=2240
      2、在你的磁盘上任意位置创建文件夹：“myplugins/svn”。名字可以任取，为了方便插件管理，建议名称为“myplugins”。
      3、将解压的svn里的两个文件夹拷贝到“myplugins/svn”下。
      4、复制下列java代码，修改路径并执行：
      package app;
      import java.io.File;
      import java.util.ArrayList;
      import java.util.List;
      /**
      * MyEclipse9 插件配置代码生成器
      *
      *
      */
      public class PluginConfigCreator
      {
      public PluginConfigCreator()
      {
      }
      public void print(String path)
      {
      List<String> list = getFileList(path);
      if (list == null)
      {
      return;
      }
      int length = list.size();
      for (int i = 0; i < length; i++)
      {
      String result = "";
      String thePath = getFormatPath(getString(list.get(i)));
      File file = new File(thePath);
      if (file.isDirectory())
      {
      String fileName = file.getName();
      if (fileName.indexOf("_") < 0)
      {
      print(thePath);
      continue;
      }
      String[] filenames = fileName.split("_");
      String filename1 = filenames[0];
      String filename2 = filenames[1];
      result = filename1 + "," + filename2 + ",file:/" + path + "/"
      + fileName + "//,4,false";
      System.out.println(result);
      } else if (file.isFile())
      {
      String fileName = file.getName();
      if (fileName.indexOf("_") < 0)
      {
      continue;
      }
      int last = fileName.lastIndexOf("_");// 最后一个下划线的位置
      String filename1 = fileName.substring(0, last);
      String filename2 = fileName.substring(last + 1, fileName
      .length() - 4);
      result = filename1 + "," + filename2 + ",file:/" + path + "/"
      + fileName + ",4,false";
      System.out.println(result);
      }
      }
      }
      public List<String> getFileList(String path)
      {
      path = getFormatPath(path);
      path = path + "/";
      File filePath = new File(path);
      if (!filePath.isDirectory())
      {
      return null;
      }
      String[] filelist = filePath.list();
      List<String> filelistFilter = new ArrayList<String>();
      for (int i = 0; i < filelist.length; i++)
      {
      String tempfilename = getFormatPath(path + filelist[i]);
      filelistFilter.add(tempfilename);
      }
      return filelistFilter;
      }
      public String getString(Object object)
      {
      if (object == null)
      {
      return "";
      }
      return String.valueOf(object);
      }
      public String getFormatPath(String path)
      {
      path = path.replaceAll("////", "/");
      path = path.replaceAll("//", "/");
      return path;
      }
      public static void main(String[] args)
      {
      /*你的插件的安装目录*/
      String plugin = "改成安装目录//Genuitec//svn";
      new PluginConfigCreator().print(plugin);
      }
      }
      这里需要注意的是修改成为刚才svn所在路径，建议改为绝对路径。比如d:/myplugins/svn/。。。
      5、 找到“$myeclipse_home/configuration /org.eclipse.equinox.simpleconfigurator/”，打开其中的“bundles.inf”文件，为了防止分不清是不 是我们自己后加的东西，在最后面多回几次车，然后粘贴第4步运行后的代码，保存
      6、重启myeclipse
